First aid and CPR/AED training saves lives, but only when your skills are current. Many people complete their certification once and assume it lasts indefinitely. In Canada, that is not the case. Understanding how long your certificate is valid, when you are eligible to recertify, and what your employer is legally required to provide will help you stay prepared and stay compliant.
How Long Is a First Aid Certificate Valid in Canada?
All first aid and CPR/AED certificates issued by the Canadian Red Cross are valid for three years from the date of completion. This applies to Intermediate / Standard First Aid, Basic / Emergency First Aid, and CPR/AED courses at every level. After three years the certificate expires and you are no longer considered a certified first aider for workplace or personal purposes.
Three years may seem like a short validity window, but it reflects an important reality: first aid guidelines are updated regularly as research uncovers better techniques, and skills that are not practised regularly fade, with CPR skill retention starting to decline significantly within 3 to 6 months after initial training. Theoretical knowledge may remain intact for up to 2 years, but physical CPR skills can degrade within 30 to 90 days. Retraining ensures you are applying current best practices, not methods that may have been revised since your last course. Brief, spaced practice every 1 to 3 months also helps people respond effectively in real emergencies.
What Are the Two Levels of First Aid and CPR/AED Training?
In Canada, first aid training is structured around two primary certification levels. Both cover core life-saving skills, but they differ significantly in scope and duration.
Basic / Emergency First Aid and CPR/AED
Basic / Emergency First Aid is a focused, entry-level course covering the most immediately critical skills: CPR, AED operation, choking response for adults, children, and infants, controlling external bleeding, and managing breathing emergencies. It is the faster pathway to certification and is suitable for individuals, caregivers, and lower-risk workplaces. Basic / Emergency First Aid certificates do not have a recertification option in Ontario; when the certificate expires, you must retake the full course.
Intermediate / Standard First Aid and CPR/AED
Intermediate / Standard First Aid is the more comprehensive certification. It covers everything in Basic / Emergency First Aid and adds training on spine, bone, and muscle injuries, environmental emergencies such as heat stroke and hypothermia, poisoning, and a wider range of medical conditions in line with national standards. Intermediate / Standard First Aid is required for many workplaces and regulated industries across Canada. It is often used to meet workplace occupational first aid requirements, with the occupational first aid level employers need depending on job risk. It is also the only certification level that offers a recertification course, allowing eligible holders to renew their credentials in a shorter format without repeating the full program. You can learn more about Intermediate / Standard First Aid course details and schedules on the courses page.
What Does WSIB Require for Workplace First Aid Training in Ontario?
For Ontario employers, first aid training is not optional. Under the province’s occupational health and safety regulations, every workplace must have a designated number of certified first aiders present on each shift, and employers are responsible for ensuring first aid services are provided at their workplaces. The required certification level depends on the size of the workforce on that shift.
Workplaces with five or fewer workers on a shift must have at least one person certified in Basic / Emergency First Aid and CPR/AED. Employers should also assign a representative to complete a first aid assessment and oversee the first aid program. Workplaces with more than five workers on a shift must have at least one person certified in Intermediate / Standard First Aid and CPR/AED. These requirements apply regardless of industry, and employers are responsible for ensuring their first aiders maintain valid, unexpired certifications at all times.
Employers should track expiry dates for all certified first aiders and schedule refresher training well in advance of expiry. Private group training can be arranged for teams that need to recertify multiple employees at once, which reduces scheduling disruptions and keeps the entire workforce compliant at the same time. The private group training option is a practical solution for workplaces with multiple staff due for renewal.
What Are the Requirements to Enrol in a First Aid Recertification Course?
Not everyone is eligible for a recertification course. Before registering, confirm that you meet all of the following criteria.
You must:
- Hold a Intermediate / Standard First Aid certificate from a full training course (not from a previous recertification)
- Have a certificate that is still valid and has not yet expired
- Attend 100% of the scheduled course hours
- Score at least 75% on the written assessment to receive your new three-year certificate
If your certificate has expired, or if you completed Basic / Emergency First Aid rather than Intermediate / Standard First Aid, you are not eligible to recertify. You will need to enrol in and complete the full training course.
The One-Recertification Rule
Intermediate / Standard First Aid can only be recertified once. After completing a recertification course, the resulting certificate cannot itself be recertified when it expires three years later. At that point you must retake the full Intermediate / Standard First Aid training course again. This creates a repeating cycle: full course, then one recertification, then full course again. This rule ensures all first aiders periodically return to the complete curriculum, reinforcing foundational knowledge alongside updated guidelines.
How Long Does a First Aid Recertification Course Take?
Recertification courses are considerably shorter than full training courses and emphasize hands-on skills practice over introductory theory. Healthcare professionals often renew basic life support annually because these high-stakes skills need to stay sharp. The focus is on reinforcing the techniques most critical in real emergencies: CPR with AED use, the recovery position, wound care and bandaging, and choking response.
Intermediate / Standard First Aid and CPR Level C Recertification
The in-class Intermediate / Standard First Aid and CPR Level C recertification course is eight hours long and requires full attendance. A blended course is available for private group training, consisting of four hours of online pre-learning followed by four hours of in-person skills practice. Both formats lead to the same three-year certificate on successful completion. Browse available recertification course schedules to find a session that fits your timeline. This option can also serve as an aid training program for workplaces that need tailored recertification.
CPR Level C Recertification
CPR/AED Level C can be recertified more than once, unlike Intermediate / Standard First Aid. The in-class recertification course is four hours long. A blended option combines two hours of online learning with two and a half hours of in-person training. CPR Level C is one of the new courses or updated course options commonly used for workplace compliance in Canada. You can view CPR/AED course options for full and recertification schedules.
What Certificate Do You Receive After Recertification?
Immediately upon completing the course, you receive a temporary certificate with 30-day validity. Within five business days, a PDF copy of your official three-year certificate is sent to you by email, and major providers such as the Canadian Red Cross and john ambulance issue credentials with validity periods that depend on the course. This certificate is issued by the Canadian Red Cross and is recognized for workplace compliance across Canada.
Which Certifications Do Not Have a Recertification Option?
Two certification types require a full course retake regardless of whether the certificate is still valid:
- Basic / Emergency First Aid and CPR/AED: No recertification pathway exists in Ontario. Retake the full course when your certificate expires.
- CPR-A: CPR-A does not support recertification. To maintain CPR-A credentials, you must complete the full course again.
If you currently hold Basic / Emergency First Aid and expect to need Intermediate / Standard First Aid certification for a new role or WSIB compliance, it is worth registering for the full Intermediate / Standard First Aid course rather than simply renewing at the Emergency level. This gives you access to the recertification pathway going forward.
Time to Recertify Your First Aid?
Find a Intermediate / Standard First Aid or CPR/AED recertification course and keep your credentials current.
Need to Train Your Entire Team?
Private group training brings the course to your workplace and keeps your whole shift WSIB-compliant at once, provided employers book through an approved training provider. For Ontario workplaces, confirm the provider is WSIB approved and that the onsite session is led by a qualified aid instructor.
Key Takeaway
First aid and CPR/AED certificates in Canada are valid for three years. Intermediate / Standard First Aid holders with a valid, unexpired certificate from a full course can take a shorter recertification course instead of repeating the full program, but this option is available once only before they must retake the full course. Basic / Emergency First Aid and CPR-A certificates have no recertification pathway. Ontario employers must ensure at least one certified first aider is present on every shift, with the required level tied to the number of workers.

If you hold a valid Intermediate / Standard First Aid certificate that has not yet expired, you may be eligible to take a shorter recertification course instead of repeating the full program.
Q2: Can you recertify an expired first aid certificate?
A: No. You cannot recertify an expired first aid certificate. Recertification is only available for certificates that are still valid at the time of the course. If your certificate has already expired, you must enrol in and complete the full first aid training course to earn a new three-year certification.
Q3: How long is a Intermediate / Standard First Aid certificate valid in Canada?
A: A Intermediate / Standard First Aid and CPR/AED certificate issued by the Canadian Red Cross is valid for three years from the date of completion. After three years, the certificate expires and you must either take a recertification course (if eligible) or retake the full Intermediate / Standard First Aid course to maintain valid certification.
Q4: What are the requirements to take a Intermediate / Standard First Aid recertification course?
A: To enrol in a Intermediate / Standard First Aid recertification course, you must hold a valid Intermediate / Standard First Aid certificate from a full training course (not from a previous recertification).

A: You can only recertify a Intermediate / Standard First Aid certificate once. After completing a recertification course, the resulting certificate cannot itself be recertified. When that second certificate expires after three years, you must retake the full Intermediate / Standard First Aid training course. This creates an alternating cycle: full course, then recertification, then full course again.
Q7: What does WSIB require for workplace first aid training?
A: Under Ontario’s WSIB regulations, the level of first aid training required depends on the number of workers on a shift. Workplaces with up to five workers on a shift must have at least one person with Basic / Emergency First Aid and CPR/AED certification. Workplaces with more than five workers on a shift must have at least one person with Intermediate / Standard First Aid and CPR/AED certification. Employers are responsible for ensuring compliance. This also includes maintaining suitable aid equipment and aid kits. The first aid kit contents should match workplace needs and applicable standards.

Q8: What is the difference between Basic / Emergency First Aid and Intermediate / Standard First Aid?
A: Basic / Emergency First Aid is a shorter course covering the most critical life-saving skills, including CPR, AED use, choking response, wound care, and breathing emergencies. Intermediate / Standard First Aid is a more comprehensive program that builds on those skills and also covers spine, bone, and muscle injuries, environmental emergencies, poisoning, and a wider range of medical conditions. Both levels are valid for three years in Canada.
Q9: How long does a Intermediate / Standard First Aid recertification course take?
A: The in-class Intermediate / Standard First Aid and CPR Level C recertification course is eight hours long and requires 100% attendance. A blended course option is also available for private group training, which consists of four hours of online learning followed by four hours of in-person skills practice. Both formats result in the same three-year certificate upon successful completion.
Q10: Can you recertify a CPR/AED certificate in Canada?
A: Yes. CPR/AED Level C certificates can be recertified, and unlike Intermediate / Standard First Aid, you can recertify CPR Level C more than once. The in-class CPR Level C recertification course is four hours long. A blended option combines two hours of online learning with two and a half hours of in-person training. Both formats produce a valid three-year certificate.
Q11: What certificate do you receive after completing a recertification course?
A: Upon completing a recertification course, you receive a temporary certificate with 30-day validity immediately after class. Within five business days, you receive a PDF copy of your official three-year certificate by email. This certificate is issued by the Canadian Red Cross and is recognized across Canada for workplace compliance and personal certification purposes.
Q12: Does CPR-A have a recertification option in Canada?
A: No. CPR-A does not have a recertification pathway. When a CPR-A certificate expires, you must retake the full CPR-A training course to become recertified. If you are looking for a certification level with a recertification option, CPR Level C is the appropriate choice, as it supports recertification and is the level required for most workplace first aid compliance.
Q13: Is first aid training required by law for Canadian employers?
A: Yes. Canadian employers have a legal obligation under occupational health and safety legislation to ensure that trained first aiders are present in the workplace. In Ontario, WSIB regulations specify which certification level is required based on the number of workers per shift. Some workplaces may also require an aid attendant with the appropriate occupational first aid level depending on the work setting. Failure to maintain compliant first aid coverage can result in workplace orders and financial penalties during inspections.
Q14: What skills are covered in a first aid recertification course?
A: A Intermediate / Standard First Aid recertification course focuses heavily on hands-on skills practice rather than introductory theory. Topics covered include CPR with AED use, the recovery position, bandaging and wound management, choking response for adults, children, and infants, and recognition of common medical emergencies, helping learners prepare to provide prompt first aid treatment. The course refreshes all core skills from the original certification and incorporates any updates to current first aid guidelines, so an injured person can receive faster, more confident care.
Q15: Should I take a full first aid course or a recertification course?
A: The right choice depends on your current certification status. If you hold a valid, unexpired Intermediate / Standard First Aid certificate from a full course (not a prior recertification), you are eligible for a recertification course. If your certificate has expired, if you hold an Basic / Emergency First Aid certificate, or if you have never been certified before, you must take the full training course. When in doubt, check your certificate’s expiry date before registering.
