Ontario’s workplace first aid requirements are governed by Regulation 1101 under the Workplace Safety and Insurance Act. These rules dictate how many first aiders you need on a shift, what goes inside your first aid kits, and what training counts as valid for compliance. In 2026, the WSIB First Aid Program was modernized to align with national Canadian Standards Association standards, marking the most significant update to workplace first aid training in years. This guide explains what changed, what stayed the same, and exactly what your Ontario workplace needs to comply.

What Are the WSIB First Aid Requirements in Ontario?

Ontario Regulation 1101 under the Workplace Safety and Insurance Act governs workplace first aid requirements for most Ontario employers. The regulation applies to all workplaces covered by WSIA regardless of industry and sets clear minimum standards every employer must meet.

The core legal obligations under Regulation 1101 include having at least one trained first aider available on every shift while workers are on duty, maintaining first aid kits with contents prescribed by the regulation based on workforce size, posting the WSIB Form 82 “In Case of Injury at Work” poster, keeping records of all first aid treatment provided in the workplace, and conducting quarterly inspections of first aid supplies and equipment.

These requirements apply regardless of employment status. Full-time, part-time, seasonal, contract, and temporary workers all count toward your shift headcount. Remote or off-site locations where employees regularly work are also covered. Construction workplaces face additional requirements under Ontario Regulation 213/91, and higher-risk employers should consider exceeding the minimums in Regulation 1101.

For a full breakdown of every change under the 2026 WSIB First Aid Program and what stayed the same, see the official information at wsib.ca/en/firstaid.

What Changed in the WSIB First Aid Program on June 22, 2026?

The Workplace Safety and Insurance Board updated its First Aid Program effective June 22, 2026 to align with the Canadian Standards Association’s CSA Z1210:24 standard for workplace first aid training. The main goals include standardized curriculum across all approved training providers in Ontario, improved quality management and consistent learner evaluation, updated practical skills relevant to today’s workplaces, and expanded provider networks to improve access across the province.

The most visible change is the course name update. Emergency First Aid is now called Basic First Aid (formerly Emergency First Aid) in training. Standard First Aid is now called Intermediate First Aid (formerly Standard First Aid). An important nuance: in the text of Regulation 1101 itself, the names Emergency First Aid and Standard First Aid remain unchanged. The new names Basic First Aid and Intermediate First Aid appear in the updated training program under CSA Z1210:24. For compliance purposes, Basic First Aid is accepted as equivalent to Emergency First Aid, and Intermediate First Aid is accepted as equivalent to Standard First Aid.

Regulation 1101 compliance thresholds have not changed. The employee-per-shift thresholds, the three-year certificate validity period, and the requirement to use WSIB-approved providers all remain exactly the same. Certificates issued before June 22, 2026 by approved providers remain valid until their printed expiry date. For the most current information, visit the official WSIB first aid page.

There are also important changes for instructors. Instructors must be 18 years or older to teach under the new program and must complete a First Aid Update Course. Emergency First Aid instructors must complete a transition course to continue teaching. All providers must reapply for approval under the updated program requirements. After June 22, 2026, only providers approved under the updated program can issue valid certificates.

How Many Employees Determine Which First Aid Level You Need?

The required first aid training level under Regulation 1101 depends on the number of workers present on any given shift. Here is exactly how it breaks down:

Workplaces With 1 to 5 Employees Per Shift: Basic First Aid

Workplaces with one to five workers per shift must have at least one worker certified in Basic First Aid (formerly Emergency First Aid). This is a one-day course of approximately 6 to 8 hours covering CPR, AED use, choking response, bleeding control, shock management, and recognition of common medical emergencies. You can read a full breakdown of what the course covers in our guide on what is Basic First Aid in Ontario.

Workplaces With 6 or More Employees Per Shift: Intermediate First Aid

Workplaces with six to 199 workers per shift must have at least one worker certified in Intermediate First Aid (formerly Standard First Aid). This is a two-day course of approximately 13 hours covering everything in Basic First Aid plus head and spine injuries, fractures and dislocations, eye injuries, burns, environmental emergencies, poisoning, and multi-casualty management. Our full guide on Intermediate First Aid courses in Ontario covers registration options and course formats in detail.

Workplaces With 200 or More Employees Per Shift: First Aid Room

Workplaces with 200 or more workers per shift must maintain a fully equipped first aid room under Section 11 of Regulation 1101. The first aid room must include washbasins, running water, instrument sterilizers, a stretcher, and appropriate medical supplies, and must be staffed by a qualified first aid attendant or nursing staff on every shift. These large workplaces must also maintain the appropriate number of trained first aiders throughout the facility.

There is no fixed ratio of first aiders to total employees under the regulation. The requirement is that at least one qualified person must be present on every shift. WSIB guidance recommends employers ensure first aiders are accessible throughout the facility so any injured worker can receive help promptly. Employers with large footprints, multiple floors, or remote worksites should train additional staff beyond the legal minimum to ensure practical coverage on every shift.

As best practice, train more than the minimum number of certified first aiders to account for vacation, illness, shift changes, and remote work arrangements. Higher-risk workplaces in manufacturing, warehousing, and construction should treat Intermediate First Aid as their default level and consider adding AED training or Basic Life Support certification where appropriate.

What First Aid Kits Does WSIB Require in Ontario?

Regulation 1101 specifies first aid kit requirements that are just as important as training. Employers must provide specific kits based on employee numbers per shift, maintained in good condition in easily accessible locations throughout the workplace.

All first aid kits must include a current edition of an approved first aid manual. Kits must be inspected at least quarterly under Regulation 1101, with inspection records showing the date and signature of the inspector. Any depleted or expired items must be replaced immediately. CSA Z1220-17 compliant kits are accepted as an alternative to the Regulation 1101 kit lists, giving employers flexibility in their sourcing.

Additional requirements and best practices: Automated External Defibrillators are strongly recommended for larger workplaces. Under Ontario Regulation 213/91, all construction sites active for longer than three months must have an AED on-site. Workplaces must also provide naloxone kits where required by Ontario law. Employers should consider extra gloves, pocket masks, and hazard-specific items beyond the regulatory minimum to reflect the actual risks in their workplace.

The Real Cost of Non-Compliance: OHSA Penalties in Ontario

Ontario now has the highest occupational health and safety penalties in Canada. Under the Occupational Health and Safety Act, corporations found in violation of workplace safety requirements, including first aid deficiencies under Regulation 1101, can face fines up to $2,000,000 per offence. Directors and officers of corporations face personal liability up to $1,500,000. All other individuals face fines up to $500,000. Convictions can also carry up to 12 months imprisonment.

The enforcement landscape grew significantly more rigorous in 2025. Under Bill 30, the Working for Workers Seven Act, Ontario Ministry of Labour inspectors can now issue Administrative Monetary Penalties directly without court prosecution. This means financial penalties can be applied faster and more broadly than before. An inspector conducting a routine visit can issue a penalty on the spot for a first aid deficiency, an unsigned inspection log, or an expired certificate, without the process going to court.

For repeat offenders, the consequences escalate further. A corporation convicted of a second or subsequent offence resulting in the death or serious injury of a worker within a two-year period faces a minimum fine of $500,000 regardless of mitigating circumstances. First aid deficiencies are among the most common triggers for Ministry of Labour compliance orders. An expired certificate or a missing kit inspection record can establish the first link in that chain, setting the stage for dramatically elevated penalties if a subsequent incident occurs.

The cost of a compliant first aid program, including training, kits, and recertification, is a fraction of a single compliance order. For most Ontario workplaces, maintaining compliance is not just a legal obligation but the most cost-effective safety investment available.

Your 2026 WSIB First Aid Compliance Audit Checklist

Use this checklist to audit your current first aid program before the next Ministry of Labour inspection or before your next training renewal cycle. Every item on this list is a requirement under Regulation 1101 or a direct compliance risk that inspectors commonly flag.

Training and Certification

Confirm the number of workers on your busiest shift. If one to five, at least one must hold a valid Basic First Aid certificate. If six or more, at least one must hold a valid Intermediate First Aid certificate. Check every certificate expiry date. A certificate that expires tomorrow is the same compliance risk as one that expired six months ago. Confirm your training provider is on the current WSIB approved provider list under the updated 2026 program. Confirm you have enough certified first aiders to cover every shift, including during vacations and sick days.

First Aid Kits and Equipment

Verify your kit type matches your workforce size: Section 8 for one to five workers, Section 9 for six to fifteen, Section 10 for sixteen to 199, with a stretcher and two blankets if you have sixteen or more. Check that all kit contents are present, unexpired, and in usable condition. Confirm your kit includes a current edition of an approved first aid manual. If you have 200 or more workers per shift, verify your first aid room is fully stocked and staffed on every shift.

Documentation and Signage

Check that the WSIB Form 82 “In Case of Injury at Work” poster is posted prominently near every first aid station. Confirm quarterly kit inspection records are up to date with dates and inspector signatures. Verify your first aid incident log is current and all treatments are recorded. For construction sites active more than three months, confirm an AED is on-site as required by Ontario Regulation 213/91.

What Are the Other WSIB Workplace First Aid Compliance Requirements?

Beyond training and kits, Regulation 1101 requires employers to document all first aid incidents and, when required, report injuries and illnesses to WSIB using Form 7 for lost-time or medical-aid injuries. Employers must keep a first aid log or treatment record, and accurate documentation supports both compliance and internal workplace safety analysis.

Employers must also conduct a written first aid assessment for each workplace. This assessment determines the appropriate aid level, number of certified first aiders needed, and the size and type of kits required. Use your first aid incident data to improve your overall program. Look for trends such as recurring injuries in specific areas, frequent supply shortages, or gaps in coverage during certain shifts.

The 2026 modernization is an ideal trigger for a complete program review covering training certifications, kit contents, signage, incident reporting processes, and emergency response plans. Treat it as an opportunity to build a safer workplace rather than just a name-change exercise.

Industry-Specific First Aid Requirements in Ontario

While Regulation 1101 applies to most Ontario workplaces, several industries face additional or enhanced first aid obligations based on their specific risk profiles.

Construction and Industrial Workplaces

Construction workplaces are subject to additional requirements under Ontario Regulation 213/91 in addition to Regulation 1101. All construction sites active for longer than three months must have an Automated External Defibrillator on-site. Industrial workplaces with higher injury risk should train first aiders at the Intermediate First Aid level regardless of shift headcount and consider advanced training for supervisors and safety officers. In 2024, Ontario’s industrial sector reported 26 workplace fatalities, down from 32 in 2023, reflecting a sector where first aid readiness can be the difference between survival and a fatality.

Healthcare and Clinical Settings

Healthcare professionals in clinical settings typically require Basic Life Support rather than a standard workplace first aid certificate. BLS covers high-performance CPR, multi-rescuer scenarios, and advanced airway management beyond what Regulation 1101 requires for most workplaces. Hospitals, clinics, dental offices, and other healthcare environments should confirm whether their specific role and regulatory body requires BLS, Intermediate First Aid, or both.

Schools, Child Care, and Youth Organizations

Schools, licensed child care centres, and youth organizations often require Intermediate First Aid as their minimum standard regardless of shift headcount, given the higher duty of care for children. Many licensing bodies and funders require CPR/AED Level C with infant and child components alongside the first aid certificate. Staff in these settings should verify the specific requirements of their licensing body, school board, or regulatory authority in addition to WSIB Regulation 1101.

What Happens If Your Workplace Is Not First Aid Compliant?

Non-compliance with Regulation 1101 triggers consequences at multiple levels. A Ministry of Labour inspector can issue an order to comply, a stop-work order, or an Administrative Monetary Penalty on the spot without court involvement. Under the Occupational Health and Safety Act, a corporation convicted of a violation faces fines up to $2,000,000. Directors and officers face personal liability up to $1,500,000. For a second or subsequent corporate offence resulting in worker death or serious injury within two years, a minimum $500,000 fine applies regardless of mitigating circumstances.

Non-compliance also affects your WSIB experience rating, increasing your premium costs over time. If a worker is injured and no certified first aider is present, the employer faces compounded liability: WSIB penalties, OHSA prosecution risk, potential civil claims, and the human cost of a preventable outcome.

The most common compliance gaps found during inspections are expired certificates, first aiders who have left the company without replacements being trained, kits that have not been restocked after use, missing or unsigned quarterly inspection records, and missing or outdated Form 82 signage. A quick audit of these five areas will identify most compliance risks before an inspector does.

Choosing a WSIB-Approved First Aid Training Provider in 2026

For your workplace first aid training to count toward compliance under Regulation 1101, you must use a WSIB-approved training provider. Only providers approved under the updated program can issue valid certificates after June 22, 2026. When selecting a provider, confirm current WSIB approval status under the updated program, alignment with CSA Z1210:24, proven experience delivering workplace first aid and CPR/AED training, availability of blended learning, and the ability to deliver on-site training across Ontario.

Some national organizations advertise “Canada-wide approval” but Ontario employers must specifically verify WSIB approval. Check provider status at wsib.ca/en/firstaid or email firstaid@wsib.on.ca directly to confirm.

Coast2Coast First Aid and Aquatics is a WSIB-approved Canadian Red Cross training partner offering Basic First Aid, Intermediate First Aid, CPR/AED Level C, Basic Life Support, and recertification courses tailored to Ontario workplaces.

View our WSIB compliance page for a full overview of compliance-focused training options.

How to Get Your Workplace First Aid Compliant Quickly

Getting compliant does not need to be complicated. Start by auditing your current state: count the number of workers on your busiest shift, check the expiry dates on all existing certificates, verify your kit contents and inspection records, and confirm your Form 82 is posted. Then determine which level you need. One to five employees per shift requires Basic First Aid. Six or more requires Intermediate First Aid.

Book training with a WSIB-approved provider before any certificates lapse. For teams of five or more, private on-site group training is typically faster, more cost-effective, and less disruptive than sending staff to public courses individually. Basic First Aid takes one day. Intermediate First Aid takes two days. Coast2Coast can schedule private on-site training at your workplace with as little as a few days notice for larger groups. Contact Coast2Coast directly to discuss priority scheduling if your compliance deadline is urgent.

WSIB First Aid Requirements: Basic First Aid vs Intermediate First Aid

Frequently Asked Questions: WSIB First Aid Requirements 2026 Ontario

More FAQs: WSIB Compliance and Workplace First Aid

If you have searched for what is intermediate first aid in Ontario, the short answer is this: it is the current CSA-compliant term for the workplace first aid training course formerly known as Standard First Aid. The name changed as part of a national effort to align aid training across Canada under the Canadian Standards Association Z1210:24 standard. This guide covers what the course includes, who needs it, how the legal requirements work, and what changed on June 22, 2026.

What Is Intermediate First Aid in Ontario?

Intermediate First Aid (formerly Standard First Aid) is Ontario’s WSIB-approved two-day workplace first aid course, renamed on June 22, 2026 under the updated WSIB First Aid Program aligned with CSA Z1210:24 national standards. It is a comprehensive 13-hour course that builds on Basic First Aid (formerly Emergency First Aid) by adding skills like head and spine injury management, environmental emergency response, fractures and dislocations, and multiple casualty triage.

In Ontario, Intermediate First Aid is the most widely recognized certification for designated workplace first aiders. It sits at Level 2 in a two-tier system where Basic First Aid is Level 1 and Intermediate First Aid is Level 2 under CSA Z1210:24. It is required for all workplaces with six or more employees per shift under WSIB Regulation 1101, and it is the standard expectation across construction, manufacturing, schools, child care, and most higher-risk industries.

For a full breakdown of every change under the updated program and what stayed the same, see our complete guide on the WSIB first aid name change Ontario 2026.

Why Did the Name Change From Standard First Aid to Intermediate First Aid?

Between 2024 and 2026, Canada adopted new workplace first aid standards to improve training consistency and quality across provinces. The Canadian Standards Association standard Z1210:24, titled First Aid Training for the Workplace, introduced standardized course names and curricula. Under this framework, Emergency First Aid is now called Basic First Aid and Standard First Aid is now called Intermediate First Aid.

In Ontario, WSIB Regulation 1101 remains the legal foundation for workplace first aid requirements. WSIB transitioned its approved First Aid Program to align fully with CSA Z1210:24 on June 22, 2026. After that date, course names, provider approvals, and certification formats follow the updated program.

The compliance thresholds have not changed. The number of employees per shift that determines which aid level is required, the three-year certificate validity, and the requirement to use WSIB-approved providers all remain exactly the same. Only the names changed. All existing Standard First Aid certificates remain valid until their printed expiry date. The name change does not require anyone to retrain early. For the most current information, visit the official WSIB first aid page.

What Does Intermediate First Aid Training Cover in Ontario?

Intermediate First Aid training is a 13-hour, two-day course that must meet CSA Z1210:24 and WSIB criteria to be recognized in Ontario. It covers everything in Basic First Aid plus a significantly deeper range of injury and illness management skills. Here is a full breakdown of what participants learn:

Cardiopulmonary Resuscitation (CPR) and AED Skills

Cardiopulmonary resuscitation is a core skill in every Intermediate First Aid course. CPR techniques are taught for adults, children, and infants using hands-on manikin practice to build the muscle memory needed to respond confidently during a cardiac emergency. Every Intermediate First Aid course includes Automated External Defibrillator training, and participants practice operating an AED alongside CPR. Rescue breathing techniques are also covered for managing non-breathing casualties until EMS arrives. Most Intermediate First Aid courses issue CPR/AED Level C certification alongside the first aid certificate.

Advanced Injury and Illness Management

Intermediate First Aid goes beyond the essential skills in Basic First Aid to cover more complex injuries. This includes fractures, sprains, dislocations, head and spine injuries, eye injuries, chest and abdominal injuries, and burns. Students learn immobilization techniques and how to use aid supplies like dressings, bandages, gloves, and barrier devices. Medical emergencies covered include heart attack, stroke using the FAST assessment, anaphylaxis, diabetic emergencies, seizures, and poisoning. Each scenario builds knowledge and confidence in recognizing warning signs and providing immediate care before EMS arrives.

Environmental and Multi-Casualty Emergencies

Environmental emergencies training includes recognizing and treating heat stroke, hypothermia, frostbite, and cold exposure injuries. Intermediate First Aid also introduces multiple casualty management, covering triage principles, prioritizing care when several people are injured, and coordinating with EMS upon arrival. This is a critical skill for construction sites, manufacturing plants, warehouses, and event settings where mass casualty incidents are a realistic risk.

Understanding Ontario First Aid Course Levels and Aid Level Requirements

Ontario’s WSIB-approved courses are structured into two clear aid levels under CSA Z1210:24. Understanding which aid level applies to your situation keeps all businesses covered under WSIA fully compliant.

Basic First Aid (formerly Emergency First Aid), Level 1 is a one-day course of approximately 6 to 8 hours. It covers essential life-threatening emergencies and satisfies Regulation 1101 for workplaces with one to five employees per shift.

Intermediate First Aid (formerly Standard First Aid), Level 2 is a two-day course of approximately 13 hours. It covers everything in Basic First Aid plus advanced injury and illness management, environmental emergencies, and multi-casualty scenarios. It satisfies Regulation 1101 for workplaces with six or more employees per shift and is the most widely recognized first aid certification in Ontario.

Employers can combine both aid levels with different CPR/AED levels. Intermediate First Aid with CPR/AED Level C is the standard combination for most Ontario workplaces with six or more employees per shift.

Who Needs Intermediate First Aid in Ontario?

In Ontario, WSIB requires first aid training at all workplaces regardless of size or industry. WSIB mandates that certified first aiders must be on-site on every shift. Intermediate First Aid is specifically required for workplaces with six or more employees per shift under Regulation 1101.

Workplaces most likely to require Intermediate First Aid include construction sites, manufacturing plants, warehouses, transportation hubs, logistics centres, schools, child care centres, and large offices with six or more staff on any given shift. All businesses covered by the Workplace Safety and Insurance Act must comply, whether staff are full-time, part-time, contract, or temporary.

Common roles that require or benefit from Intermediate First Aid certification include supervisors, health and safety representatives, designated first aid attendants, coaches, recreation leaders, camp staff, and anyone working in a higher-risk or larger workplace environment. Intermediate First Aid is suitable for designated first aiders in high-risk environments where serious injuries are more probable.

Child Care, Healthcare, and Specialized Roles

People who work in child care settings should pay particular attention. Many daycare centres, early childhood education programs, and youth organizations require Intermediate First Aid plus CPR/AED Level C with infant and child components. Healthcare professionals and clinical staff typically require Basic Life Support (BLS) rather than a standard workplace first aid certificate. BLS follows a separate certification cycle designed for hospital and clinical environments.

Ontario Workplace First Aid Requirements Under Regulation 1101

Ontario’s workplace first aid obligations are law under the Workplace Safety and Insurance Act (WSIA). Every employer covered by WSIA must comply with Regulation 1101, whether staff are full-time, part-time, contract, or temporary. Failing to comply can trigger WSIB penalties and increase liability if a workplace incident occurs.

Regulation 1101 requires specific first aid kits meeting CSA Z1220-17 standards, tiered by workforce size. It also requires posting of the WSIB Form 82 poster, quarterly kit inspections, written records of all workplace incidents, a written first aid assessment for each workplace, and at least one trained first aider with a valid certificate accessible on every shift.

Employers with spread-out facilities, multiple floors, or remote worksites should ensure first aiders are distributed so that any worker can receive first aid promptly on any shift. Only training from WSIB-approved providers meets Ontario workplace requirements and will be accepted during Ministry of Labour inspections, audits, or incident investigations.

How Long Is an Intermediate First Aid Course in Ontario?

An Intermediate First Aid course in Ontario runs over two full days, approximately 13 hours total including both theory instruction and hands-on skills practice. The two-day format reflects the significantly wider scope of Intermediate First Aid compared to the one-day Basic First Aid course.

In-Class Format

A certified instructor guides every skill across two consecutive classroom sessions, covering theory through to hands-on practice and scenario-based evaluation. This format suits learners who prefer a structured environment with direct instructor feedback throughout both days.

Online Blended Learning Format

Blended learning allows participants to complete theory modules online at their own pace before attending a scheduled in-person skills session. This format reduces total classroom time while still meeting every WSIB and CSA Z1210:24 requirement. A fully online course with no practical skills evaluation is never valid for WSIB workplace compliance under Regulation 1101, regardless of the provider.

Intermediate First Aid vs Basic First Aid: What Is the Difference?

Intermediate First Aid and Basic First Aid (formerly Emergency First Aid) share the same foundation but differ significantly in scope, duration, and the workplaces they satisfy under Regulation 1101.

First Aid and CPR/AED: Choosing Between Level C and BLS

First aid and CPR are closely linked but serve distinct roles. Intermediate First Aid combined with CPR/AED Level C is the standard combination for most Ontario workplaces with six or more employees per shift. CPR/AED Level C covers cardiopulmonary resuscitation and AED use for adults, children, and infants, plus choking emergencies. CPR/AED certification is valid for three years, and Heart and Stroke Foundation of Canada recommends annual renewal of CPR/AED skills because cardiopulmonary resuscitation techniques degrade faster than other first aid knowledge.

Basic Life Support (BLS) is a more advanced cardiopulmonary resuscitation course designed for healthcare providers and first responders. It covers high-performance CPR, multi-rescuer scenarios, airway management, and rescue breathing techniques that go beyond what standard workplace first aid requires. Choose CPR/AED Level C for most non-healthcare workplaces and the general public, and BLS for hospitals, clinics, paramedic services, and professional responder positions.

Can You Recertify Intermediate First Aid in Ontario?

Yes. Intermediate First Aid can be recertified in Ontario. To qualify, you must hold a current, non-expired Intermediate First Aid certificate or an equivalent Standard First Aid certificate issued before June 22, 2026. Recertification must be completed before the certificate expires. There is no grace period after expiry.

The recertification course is typically completed in one day rather than repeating the full two-day program. Upon successful completion, the certificate validity resets for another three years. After this single recertification, the next renewal requires the full two-day course again.

This is different from Basic First Aid, which cannot be recertified at all. When a Basic First Aid certificate expires, the full course must be retaken. There is no grace period after expiry for either level. Book your recertification course before your current certificate expires to avoid any gap in coverage for your workplace.

Intermediate First Aid Certification, Validity, and Recertification in Ontario

Most WSIB-approved Intermediate First Aid certificates issued through Canadian Red Cross partners are valid for three years from the date of completion. CPR/AED certification is also valid for three years. Heart and Stroke Foundation of Canada recommends annual renewal of CPR/AED skills because cardiopulmonary resuscitation techniques degrade faster than other first aid knowledge. Even before your full first aid certificate expires, refreshing CPR and AED competency each year keeps your response sharp and your workplace prepared.

Coast2Coast maintains digital records of certification and can help learners schedule recertification before their certificate expires so there are no gaps in workplace compliance. Employers coordinating training for multiple staff should track expiry dates across the team and plan renewal training well in advance of the earliest expiry.

Frequently Asked Questions: Intermediate First Aid Ontario 2026

More FAQs: Intermediate First Aid Certification and Training

If you work in Ontario or manage a team, understanding what Basic First Aid means is not optional. It is a legal requirement, a workplace safety standard, and a set of essential skills that can save a life when seconds count. This guide breaks down exactly what Basic First Aid covers in Ontario, what the law demands, and how to get properly certified under the 2026 WSIB program.

What Is Basic First Aid in Ontario?

In plain language, Basic First Aid is the foundation of emergency care that any person can provide before professional medical help arrives. It covers how to recognize a problem, keep someone alive, and prevent an injury or illness from getting worse. The skills covered in first aid training at this level meet WSIB’s legislative requirements for entry-level workplace certification.

In Ontario, first aid training programs are dictated by the Workplace Safety and Insurance Board, and the term carries specific regulatory weight. People often say “basic first aid” when they mean the entry-level WSIB-approved first aid training designed for workplaces, schools, organizations, and the general public. Officially, WSIB used the name Emergency First Aid for this level for many years. Emergency First Aid training focuses on recognizing emergencies and providing immediate intervention. After June 22, 2026, Emergency First Aid is now officially called Basic First Aid (formerly Emergency First Aid) under the new WSIB First Aid Program, which aligns Ontario’s aid training with the national CSA Z1210:24 standard.

The emergency action steps taught in Basic First Aid include assessing the scene for safety and contacting 9-1-1, followed by providing immediate care until EMS arrives. Medical emergencies recognition is essential in first aid courses, covering conditions like cardiac arrest, stroke, allergic reactions, and diabetic emergencies. First aid training includes recognizing signs of shock and managing unconscious patients.

For a full breakdown of every change under the updated program and what stayed the same, see our complete guide on the WSIB first aid name change Ontario 2026.

Why Did the Name Change From Emergency First Aid to Basic First Aid?

The name change is part of WSIB’s updated First Aid Program, launched on June 22, 2026, which aligns Ontario’s workplace first aid training with the national CSA Z1210:24 standard. The goal is to standardize course names across Canada so that employers, employees, and training providers in every province follow the same language and quality benchmarks.

Under the updated program, two course names changed. Emergency First Aid is now Basic First Aid. Intermediate First Aid (formerly Standard First Aid) is the new name for what was previously called Standard First Aid. Regulation 1101 has not changed. The compliance thresholds, course content, and three-year certificate validity period all remain the same. Only the names are different.

All first aid certificates remain valid until their expiration date. A certificate issued before June 22, 2026 does not need to be replaced early. When it expires, the renewal will be completed under the new program names with any WSIB-approved provider.

What Does Basic First Aid Training Cover in Ontario?

Basic first aid training in Ontario is an 8-hour foundational course that covers life-threatening emergencies, scene assessment, and core essential skills needed to respond before EMS arrives. A basic first aid course covers essential life-saving skills such as CPR and AED operation, bleeding control, and response to common medical emergencies. Here is a full breakdown of what participants learn:

Cardiopulmonary Resuscitation (CPR) and AED Skills

Cardiopulmonary resuscitation is one of the most critical skills taught in Basic First Aid. CPR techniques are taught for adults and children, using hands-on manikin practice to build the muscle memory needed to respond confidently during a cardiac emergency. Automated External Defibrillator use is included in first aid training at every level. Participants learn to operate an AED safely and effectively alongside CPR. Rescue breathing techniques are also covered for managing non-breathing casualties until professional help arrives.

Bleeding Control and Wound Care

Wound care and bleeding management are critical components of first aid training. Wound management involves controlling severe bleeding and applying pressure using dressings and bandages from the first aid kit. First aid courses cover how to clear airway obstructions during choking incidents for adults and children. First aid courses also teach management for choking in adults and children as a core skill, covering back blows and abdominal thrusts.

Medical Emergencies, Shock, and Scene Management

Emergency scene management covers assessing the scene for safety, managing bystanders, and activating the emergency action plan. Medical emergencies recognition is essential in Basic First Aid courses, covering cardiac arrest, stroke, allergic reactions, asthma attacks, diabetic emergencies, and fainting. First aid training includes recognizing signs of shock and managing unconscious patients who may need to be placed in the recovery position. Recognizing and treating environmental emergencies is also included in first aid training, covering conditions such as heat stroke and hypothermia.

Understanding Ontario First Aid Course Levels and Aid Level Requirements

Ontario’s WSIB-approved courses are structured into clear aid levels. Understanding which aid level applies to your situation saves time and keeps all businesses covered under WSIA fully compliant. Courses include Basic First Aid, Emergency First Aid equivalents, and Standard First Aid equivalents, and both entry-level and intermediate levels can be combined with different CPR/AED levels.

Basic First Aid (formerly Emergency First Aid) is a one-day basic first aid course. Basic first aid training in Ontario is an 8-hour foundational course designed for entry-level certification. Courses typically take one day to complete, making them practical for individuals and smaller, lower-risk workplaces.

Intermediate First Aid (formerly Standard First Aid) is a two-day WSIB-approved course of approximately 13 hours. It goes deeper into injury and illness management, including splinting for fractures and dislocations, eye injuries, burns, environmental emergencies, head and spine injuries, poisoning, and multi-casualty scenarios. Intermediate First Aid certification is valid for three years and can be recertified once through a one-day refresher before expiry. Recertification for Intermediate First Aid is required every three years to maintain valid status.

Courses include Intermediate First Aid with CPR Level C certification as the most common combination for Ontario workplaces with six or more employees per shift.

Who Needs Basic First Aid in Ontario?

In Ontario, first aid training is required for all workplaces in the province, regardless of size or industry. WSIB mandates that certified first aiders must be on-site at workplaces on every shift. Basic First Aid (formerly Emergency First Aid) is specifically required for workplaces with one to five employees per shift under Regulation 1101.

This applies to businesses of all types: retail stores, small offices, food service operations, small construction sites, and any other workplace with a small shift headcount. All businesses covered by the Workplace Safety and Insurance Act must comply, whether staff are full-time, part-time, contract, or temporary.

Beyond the legal requirement, Basic First Aid is appropriate for a wide range of individuals including parents and caregivers, teachers and school staff, coaches and volunteers, security guards as a minimum qualification for their Ontario license, students completing placements or practicums, and anyone who wants to be prepared to respond confidently when an emergency happens.

Workplaces with six or more employees per shift are required to have at least one person certified in Intermediate First Aid (formerly Standard First Aid) on every shift. Basic First Aid alone does not satisfy Regulation 1101 for larger workplaces.

Ontario Workplace First Aid Requirements Under Regulation 1101

Ontario’s workplace first aid obligations are not suggestions. They are law under the Workplace Safety and Insurance Act (WSIA), and every employer must comply. In Ontario, first aid training programs are dictated by the Workplace Safety and Insurance Board, and WSIB-approved training providers must be selected for workplace training to meet these requirements.

Regulation 1101 requires specific first aid kits tiered by workforce size: a Section 8 kit for workplaces with one to five employees, a Section 9 kit for six to fifteen employees, and a Section 10 kit for sixteen to two hundred employees. Regulation 1101 also requires posting of the WSIB Form 82 poster, quarterly kit inspections, and at least one trained first aider with a valid certificate near every first aid station. Workplaces with two hundred or more workers per shift must maintain a dedicated first aid room with a stretcher, washbasins, and additional supplies.

The skills covered in first aid training from WSIB-approved providers meet WSIB’s legislative requirements and will be accepted during Ministry of Labour inspections, audits, or incident investigations. Some providers advertise “Canada-wide” approval, but Ontario employers must specifically confirm WSIB approval status on the WSIB website before booking to ensure compliance.

How Long Is a Basic First Aid Course in Ontario?

A Basic First Aid course in Ontario takes one full day, approximately 6 to 8 hours including both theory and hands-on skills practice. The duration is designed to cover all essential skills within a single day for convenience, making it accessible for working individuals and busy teams.

In-Class Format

The full course is delivered in a single classroom session with a certified instructor guiding every skill from start to finish. This format suits learners who prefer a structured environment and direct instructor feedback throughout the day.

Online Blended Learning Format

The blended learning format offers convenience by splitting the course into two parts. Theory modules are completed online at your own pace from home or any location before attending a shorter in-person skills session. This format reduces time in the classroom while still meeting every WSIB requirement. A fully online course with no practical skills evaluation is not valid for WSIB workplace compliance under Regulation 1101 regardless of the provider.

Basic First Aid vs Intermediate First Aid: What Is the Difference?

Basic First Aid and Intermediate First Aid (formerly Standard First Aid) are the two entry-level WSIB-approved first aid courses available in Ontario. They share the same foundation but differ in depth, duration, and the workplaces they satisfy under Regulation 1101.

Most Ontario workplaces pair their first aid course with CPR/AED Level C for complete workplace-ready certification. CPR/AED Level C covers cardiopulmonary resuscitation and AED use for adults, children, and infants.

First Aid and CPR/AED: Choosing Between Level C and BLS

First aid and CPR are closely linked but serve distinct roles. First aid addresses injuries and illnesses. CPR and AED use targets cardiac and breathing emergencies specifically.

Most Ontario workplaces choose Basic First Aid or Intermediate First Aid combined with CPR/AED Level C. CPR/AED Level C covers cardiopulmonary resuscitation and AED use for adults, children, and infants, plus choking emergencies. CPR/AED certification is valid for three years. Over 100,000 learners have been trained in CPR/AED courses through Canadian Red Cross programs. Heart and Stroke Foundation of Canada recommends annual renewal of CPR/AED skills because cardiopulmonary resuscitation techniques degrade faster than other first aid knowledge.

Basic Life Support (BLS) is a more advanced cardiopulmonary resuscitation course designed for healthcare providers and first responders. It covers high-performance CPR, multi-rescuer scenarios, airway management, and rescue breathing techniques that go beyond what standard workplace first aid requires. Choose CPR/AED Level C for most non-healthcare workplaces and the general public, and BLS for hospitals, clinics, paramedic services, and professional responder positions.

Youth and Babysitting First Aid Training in Ontario

Youth courses are available through Canadian Red Cross training partners for younger learners who are not yet ready for a full adult workplace course. These courses are designed for individuals aged 11 and older and focus on safety and leadership skills. Youth courses help prepare participants for emergency situations in everyday settings such as babysitting, school, and community activities.

Babysitting safety training is included in youth courses, covering how to respond to emergencies when caring for infants, children, and young people. These youth courses are an excellent starting point for teenagers who will eventually progress to full Basic First Aid or Intermediate First Aid certification as they enter the workforce or take on caregiving responsibilities.

WSIB First Aid Program Changes in 2026

WSIB updated its First Aid Program on June 22, 2026. All first aid certificates remain valid until their expiration date so no early retraining is required. After June 22, 2026, course names changed: Emergency First Aid is now Basic First Aid and Standard First Aid is now Intermediate First Aid. The updated program aligns with the national CSA Z1210:24 standard. Regulation 1101 has not changed and all compliance thresholds remain exactly the same.

Employers and safety coordinators should review their first aid policies before renewals coming due in late 2026 and 2027 to ensure documentation, job postings, and training records match the new WSIB First Aid Program terminology.

Can You Recertify Basic First Aid in Ontario?

No. Basic First Aid certificates cannot be recertified in Ontario. When a Basic First Aid certificate expires, the full course must be retaken. There is no shortened recertification option available for this aid level.

This is different from Intermediate First Aid, which can be recertified once through a one-day refresher course before the certificate expires. Recertification for Intermediate First Aid is required every three years to maintain valid status. After recertification, the next renewal requires the full two-day course again.

There is no grace period after expiry. The day after your expiry date, your certificate is no longer valid for workplace compliance. Book your next course before your current certificate expires to avoid any gap in coverage for your workplace.

First Aid Certification, Validity, and Recertification in Ontario

Most WSIB-approved Basic First Aid certificates issued through Canadian Red Cross partners are valid for three years from the date of completion. CPR/AED certification is also valid for three years. Heart and Stroke Foundation of Canada recommends annual renewal of CPR/AED skills because cardiopulmonary resuscitation techniques degrade faster than other first aid knowledge. Even before your full first aid certificate expires, refreshing CPR and AED competency each year keeps your response sharp and your skills prepared.

Coast2Coast maintains digital records of certification and can help learners schedule recertification before their certificate expires so there are no gaps in workplace compliance.

What Is an Allergic Reaction and Why Does It Happen?

An allergic reaction happens when the immune system treats a normally harmless substance as a threat. Instead of ignoring proteins found in peanuts, bee venom, or penicillin, the body launches a defensive response against them. This happens because the immune system misidentifies those proteins as dangerous invaders, triggering a cascade of chemical responses that produce the familiar symptoms most people associate with allergies.

During the first exposure to an allergen, the immune system creates specialized antibodies called Immunoglobulin E (IgE). These antibodies attach to mast cells throughout the body. On re-exposure to the same allergen, those IgE antibodies trigger the release of histamine and other chemicals into the bloodstream. The result is the swelling, itching, nasal congestion, and breathing difficulties that characterize an allergic response.

Reactions vary enormously in severity. The same person can experience a mild rash after one exposure and a life-threatening anaphylactic reaction at another, depending on the dose of allergen, their current health, and other cofactors like exercise or illness. In Canada, approximately 6.1% of the population has a confirmed food allergy, and many more have sensitivities to environmental allergens such as pollen, pet dander, and dust mites.

What Are the 7 Symptoms of an Allergic Reaction?

Recognizing an allergic reaction early gives you the best chance of preventing it from escalating. Symptoms can affect the skin, airways, digestive system, and circulation simultaneously, so knowing the full picture matters.

The seven hallmark symptoms to watch for are:

Mild reactions tend to stay localized: a few hives, some redness, sneezing, and watery eyes. These can often be managed with over-the-counter antihistamines, which treat symptoms like sneezing and itching. Moderate reactions escalate: spreading hives, facial or lip swelling, persistent vomiting, or wheezing require immediate medical evaluation. Any severe symptom, especially throat swelling, difficulty breathing, or loss of consciousness, is anaphylaxis until proven otherwise.

Mild vs. Moderate vs. Severe: How to Tell Which One You Are Dealing With

Not every allergic reaction is a medical emergency, but it is essential to know when one is becoming dangerous. The line between moderate and severe can move faster than most people expect.

Mild reactions are localized. The person has a few hives, some redness around the point of contact, a runny nose, or mild stomach discomfort without any breathing problems. They are fully alert and their breathing is normal. Antihistamines can treat these symptoms, but the person should still be monitored closely in case the reaction escalates.

Moderate reactions suggest the immune system response is spreading beyond its initial site. Watch for hives spreading across the body, swelling of the lips or face, a feeling of throat tightness, persistent vomiting, or coughing and wheezing. At this stage the person needs medical evaluation as soon as possible because things can get worse rapidly without warning.

Severe reactions (anaphylaxis) involve multiple organ systems at once. Throat or tongue swelling making it hard to breathe, a sudden drop in blood pressure causing dizziness or fainting, a weak or racing pulse, confusion, or loss of consciousness all indicate anaphylaxis. This is a life-threatening emergency requiring epinephrine and an immediate call to 911. Anaphylaxis typically involves symptoms affecting multiple organ systems simultaneously, which is what distinguishes it from a moderate allergic reaction.

What Are the Common Triggers of a Severe Allergic Reaction?

Certain triggers are responsible for the vast majority of serious allergic reactions in Canada. Knowing them helps you anticipate risk situations and prepare accordingly.

Food allergies are the most common cause of anaphylaxis. Health Canada identifies 10 priority allergens responsible for roughly 90% of severe adverse food reactions in the country: peanuts, tree nuts (almonds, cashews, walnuts), shellfish, fish, milk, eggs, wheat, soy, sesame, and sulphites at certain concentrations. Peanut and tree nut allergies are among the most common causes of fatal anaphylaxis. These allergens must be clearly declared on Canadian food labels, but trace amounts can appear in sauces, marinades, and processed foods that are not obviously allergen-containing. Always reading food labels carefully and looking for allergen-free foods when shopping are essential habits for anyone managing a food allergy.

Insect stings from bees, wasps, and hornets are a leading trigger for anaphylaxis in adults. Unlike food reactions, sting-induced anaphylaxis can develop within seconds of exposure, leaving almost no time to react. People with known insect sting allergies should carry an epinephrine auto-injector at all times during outdoor activities.

Medications including penicillin, sulfa drugs, and non-steroidal anti-inflammatory drugs (NSAIDs) are common pharmaceutical triggers. Always inform healthcare providers of any known drug allergies before receiving treatment.

Environmental allergens such as pollen, pet dander, animal dander, dust mites, and mold generally cause hay fever and common allergies rather than anaphylaxis, but they can worsen asthma and lower the threshold for a severe reaction in sensitized individuals. People with atopic dermatitis (eczema) are at higher risk of developing additional allergies over time.

One less commonly known trigger is exercise-induced food allergy, where eating certain foods within a few hours of physical activity causes a reaction that neither the food nor the exercise would trigger alone. Separating trigger foods and intense exercise by at least four hours can help avoid these reactions.

How Long Does an Allergic Reaction Take to Develop?

The timing of an allergic reaction depends on the type of allergen, the route of exposure, and the individual’s immune sensitivity. Understanding this timeline matters because it affects how quickly you need to act.

Reactions triggered by insect stings or injected medications can develop within seconds, with anaphylaxis beginning before the person has even processed what happened. Food-induced reactions are usually faster when food is eaten on an empty stomach, but can take anywhere from a few minutes to one to two hours to become apparent depending on how quickly the allergen is absorbed through digestion.

One important phenomenon to understand is the biphasic reaction. Symptoms may appear to improve after initial treatment, only to return several hours later without any new allergen exposure. Studies show this second wave occurs in roughly 4.6% of anaphylaxis patients, with a median recurrence around 11 hours after the initial episode. The second phase can be as severe as the first. This is why hospital observation after any treated anaphylactic reaction is strongly recommended, even when the person appears to have fully recovered.

What To Do Before the EpiPen Arrives: Step-by-Step First Aid for Anaphylaxis

The minutes before emergency medical services arrive are critical. Knowing exactly what to do, and what not to do, can be the difference between a full recovery and a tragedy. Canadian Red Cross Standard First Aid training covers anaphylaxis recognition and response in detail, but here is the essential sequence every Canadian should know.

How to Use an Epinephrine Auto-Injector

Remove the auto-injector from its case and pull off the blue safety cap. Press the orange tip firmly against the mid-outer thigh (the outside of the upper leg) and hold it in place for ten seconds. You will hear a click when the needle deploys. Remove the device and massage the injection site for ten seconds to help the medication absorb. Note the time of injection and tell paramedics when they arrive.

The epinephrine auto-injector can be used through clothing. Never inject into a vein, a buttock, or a hand or foot. The thigh delivers the fastest absorption. Each auto-injector delivers a single dose, which is why two devices should always be carried.

What If There Is No EpiPen Available?

If no epinephrine auto-injector is available when someone goes into anaphylaxis, call 911 immediately and describe the symptoms clearly. Paramedics carry injectable epinephrine and can administer it on arrival. While waiting, keep the person calm, help them lie flat with legs elevated, loosen any tight clothing around the neck and chest, and monitor their breathing closely. Do not give antihistamines as a substitute since they will not stop anaphylaxis. Be ready to begin CPR if the person loses consciousness and stops breathing normally. Every second counts, so stay on the line with the 911 dispatcher and follow their instructions.

Can You Use an Expired EpiPen in an Emergency?

Yes. If an expired epinephrine auto-injector is the only option available, use it. Research indicates that expired epinephrine retains a meaningful percentage of its active ingredient for months and in some cases years beyond the printed expiry date. A partially potent dose is far better than no treatment at all while anaphylaxis progresses. After using an expired device, call 911 immediately, report that an expired injector was used, and monitor closely for any signs that the reaction is not being controlled. Request additional epinephrine from paramedics on arrival. In rare cases the reduced potency may mean a faster return of symptoms, so vigilance is essential.

What Are the Risk Factors for a Severe Allergic Reaction?

Some people are at significantly higher risk of experiencing a life-threatening allergic reaction. Understanding these risk factors helps with planning and preparedness.

A family history of allergic conditions including asthma, eczema, or hay fever raises the likelihood of developing allergies. Existing asthma, particularly when poorly controlled, is one of the strongest risk factors for a fatal anaphylactic reaction because it compounds the breathing difficulties that anaphylaxis causes. Anyone with asthma and a known food allergy is at especially high risk and should always have an epinephrine auto-injector on hand.

A previous anaphylactic reaction to any allergen is the single most important predictor of future severe reactions. Having atopic dermatitis (eczema) or mast cell disorders also increases susceptibility. Age plays a role as well: infants and young children are more commonly affected by milk and egg allergies, while older children, teens, and adults are more commonly affected by peanut, tree nut, and shellfish allergies. Child care first aid training specifically addresses managing food allergy emergencies in children, an important consideration for anyone working in a childcare or school setting.

Cofactors that can increase the severity of a reaction include exercise, alcohol consumption, concurrent illness, and taking certain medications like NSAIDs or beta-blockers that can either mask or amplify reaction symptoms.

How to Reduce the Risk: Avoiding Triggers and Reading Food Labels

For people with confirmed severe allergies, strict avoidance of triggers is the most reliable strategy for staying safe. This requires consistent habits across several areas of daily life.

Reading food labels carefully every time is non-negotiable. Canadian food labeling regulations require that the 10 priority allergens be declared, but ingredients can change without notice and cross-contamination can occur at any point in manufacturing. Looking for allergen-free foods and products carrying “may contain” warnings is an important layer of protection. At restaurants, clearly communicating your allergy to staff and asking about preparation methods and cross-contamination practices is essential.

Preventing cross-contamination at home means using separate utensils, cutting boards, and cooking surfaces for allergen-free foods, and washing hands and surfaces thoroughly after handling known allergens. Even trace amounts found in shared cooking equipment can trigger anaphylaxis in highly sensitized individuals.

For environmental allergens, reducing exposure to pet dander, pollen, dust mites, and mold through regular cleaning, using air purifiers, and avoiding high-pollen outdoor periods helps manage common allergies and hay fever. People with atopic dermatitis should follow a skin care plan to reduce the overall allergic burden on the immune system.

Workplaces and schools can also take practical steps by maintaining clearly labeled allergen-free zones, following safe food-handling practices, and keeping up-to-date emergency contact and action plans for individuals with known allergies. Private group first aid training equips your entire team to recognize and respond to anaphylaxis confidently before paramedics arrive.

How Are Allergies Diagnosed in Canada?

Anyone who has experienced repeated allergic reactions or a single severe reaction should see a healthcare provider or allergist rather than attempt self-diagnosis. A confirmed diagnosis creates a proper emergency action plan and identifies all triggers so avoidance strategies can be put in place.

A detailed medical history is the foundation of any allergy diagnosis. Keeping a journal of symptoms for your doctor, noting what you ate, where you were, and what happened before and during the reaction, helps identify patterns that testing alone may miss. Diagnosis is guided by the Canadian Society of Allergy and Clinical Immunology (CSACI), which provides evidence-based recommendations for allergy assessment and management across the country.

Skin prick testing places small amounts of common allergens on the skin and observes for a raised, itchy wheal within 15 to 20 minutes. A patch test may be used for delayed reactions such as contact dermatitis. Blood tests measure specific IgE antibodies and are useful when skin testing is not possible, such as when the person is taking antihistamines or has extensive atopic dermatitis. Oral food challenges, conducted under medical supervision, remain the gold standard for confirming food allergy but carry a risk of severe reaction and must only be done in a specialized clinical setting.

See a doctor if allergic symptoms persist or worsen rather than trying to manage them independently with over-the-counter medications. Over-diagnosis can lead to unnecessary dietary restrictions, while under-diagnosis leaves a potentially life-threatening condition without an emergency plan.
