How Long Does a Standard First Aid Certificate Last in Ontario?
A quick, clear answer on expiry, recertification, and how to keep your card current.
A Standard First Aid certificate in Ontario is valid for 3 years from the date you finish the course. This applies whether your certificate is from the Canadian Red Cross, the Heart and Stroke Foundation, or the Lifesaving Society. The CPR component on the same card expires at the same time.
The 3-year rule, explained
Every Standard First Aid certificate issued by a WSIB-approved training agency in Ontario lasts three years. The clock starts the day you complete the course and pass the practical assessment — not the day you registered, and not the day your card arrives in the mail.
Three years is the standard across all three major Canadian training agencies — Red Cross, Heart and Stroke, and Lifesaving Society — so it doesn’t matter which one issued your card. The expiry date is printed on the front of the certificate. If you can’t find your card, your training provider can look up the date for you.
What about the CPR part?
If you took Standard First Aid with CPR C AED (the most common combination), the CPR portion shares the same 3-year expiry. The same is true for Emergency First Aid with CPR C AED.
Healthcare workers are the exception. BLS (Basic Life Support) — the version of CPR used in hospitals, clinics, and on ambulances — has a 1-year expiry. If you’re a nurse, paramedic, dentist, or healthcare student, your BLS card needs to be renewed every year, even if your first aid certification is good for three.
Recertification vs. taking the full course again
If your card is still valid (even by one day), you can take a recertification course. It’s shorter, less expensive, and refreshes the certificate for another three years. Recerts are typically about 8 hours, compared to roughly 14 hours for the full Standard First Aid course.
Once your card has expired, most agencies require you to retake the full course. Some employers and providers will accept a recertification within 30 to 90 days of expiry as a courtesy, but that’s not a guarantee — and under Ontario Regulation 1101, an expired card doesn’t satisfy your employer’s legal obligation.
When should you book your recert?
Our advice: set a calendar reminder for 60 days before your expiry date. That gives you a wide window to find a class that fits your schedule, and it avoids the panic of trying to book a course the week before your certificate lapses.
Your new 3-year clock starts the day you finish the recert — not on the old expiry date. So if you renew a month early, you’re not “wasting” that month; you’re just resetting the timer from the day you finish.
What if you let it lapse?
It happens — life gets busy. If your certificate is expired:
- If you’re under 3 months past expiry, call your training provider and ask whether they’ll accept you into a recert class. Some will.
- If you’re more than 3 months past, plan on retaking the full Standard First Aid course.
- If your employer designated you as a workplace first aider, let them know your status. They may need to designate someone else temporarily until you’re recertified.

Frequently Asked Questions
Can I renew an expired Standard First Aid certificate?
If your certificate is still within the 3-year validity window, you can take a recertification course. Once it has expired, most agencies require you to retake the full course. A small grace period is sometimes accepted, but the safest approach is to recertify before the expiry date on the card.
Does my CPR certification expire at the same time?
Yes — when CPR is bundled into a Standard First Aid course, the CPR portion shares the same 3-year expiry. For healthcare workers holding a BLS certificate, the standard is 1 year.
How early can I recertify?
Any time while your current certificate is still valid. The new 3-year clock starts the day you complete the recert. Most students book 1–2 months before expiry.
What if my workplace asks for proof and my card is expired?
An expired certificate doesn’t satisfy Ontario Regulation 1101, even by one day. You’ll typically need to complete a new course before resuming first aid responsibilities at work.
