CPR Statistics in Canada: The Numbers That Prove Training Saves Lives
Behind every cardiac arrest survival statistic is a person whose life was saved because someone nearby knew CPR. Here are the numbers — and why they should motivate you to get trained.
Roughly 35,000–40,000 out-of-hospital cardiac arrests happen in Canada each year, and only about 1 in 10 people survive (Heart & Stroke Foundation of Canada). The single biggest factor in survival is immediate bystander CPR, which can double or triple the chance of survival. Every minute without CPR and defibrillation drops survival by roughly 7–10%, and brain damage begins in just 4–6 minutes — so the person beside the patient, not the paramedic, is usually the one who decides the outcome.
Cardiac Arrest in Canada: The Big Picture

Cardiac arrest is not a rare event. It can strike anyone, at any age, often without warning. While it is more common in older adults with heart disease, it also affects young athletes, children, and otherwise healthy individuals who may have undiagnosed heart conditions.
The overall survival rate for out-of-hospital cardiac arrest in Canada is roughly 1 in 10 — a number that has improved over the past decade but still represents tens of thousands of deaths each year, many of which earlier bystander CPR and defibrillation could have prevented.

The Bystander CPR Gap
The single most important factor in surviving cardiac arrest is whether someone starts CPR before paramedics arrive. Here is the challenge: bystander CPR rates in Canada vary widely, and in many communities, they are far too low.
- Bystander CPR rates in Canada range from roughly 30 to 50 percent depending on the region — meaning that in up to half of cardiac arrests, no one performs CPR before paramedics arrive
- Fewer than 20 percent of Canadians feel confident they could perform effective CPR in a real emergency
- CPR skills decay quickly — research shows that without practice, technique quality drops significantly within 3 to 6 months of training

What the Numbers Prove: CPR Works
The evidence is overwhelming and consistent across every study:
- Bystander CPR doubles or triples survival rates compared to cardiac arrests where no bystander intervenes
- CPR plus early AED use dramatically increases survival — the combination is the most effective treatment available before advanced care arrives
- Communities with high CPR training rates (such as those in Scandinavia where CPR is taught in schools) report survival rates several times higher than the average — driven by higher bystander CPR and faster defibrillation
- Even imperfect CPR is far better than no CPR — doing something is always better than doing nothing

Where Cardiac Arrest Happens
Understanding where cardiac arrests occur underscores why training everyday Canadians — not just healthcare workers — is so critical:
- Approximately 70 percent occur at home — the person most likely to be there is a spouse, parent, child, or roommate
- 15 to 20 percent occur in public places — workplaces, shopping centres, gyms, schools, community centres
- The remainder occur in long-term care facilities, ambulances, and other settings
Source: Heart & Stroke Foundation of Canada — majority of OHCA occur in the home.
The takeaway is clear: cardiac arrest is overwhelmingly a household emergency. The first responder is almost always a family member, which is why CPR training for families is so important.
The AED Factor
Automated external defibrillators (AEDs) are the other half of the survival equation. When cardiac arrest is caused by ventricular fibrillation — the most common shockable rhythm — an AED can restore a normal heartbeat. Combined with CPR, early defibrillation is the most effective treatment available.
- AEDs are designed for anyone to use — they provide voice instructions and will not deliver a shock unless the heart rhythm requires it
- AEDs are increasingly available in schools, community centres, gyms, airports, shopping centres, and workplaces across Ontario
- For every minute of delay in defibrillation, the chance of survival decreases by approximately 7 to 10 percent

Learning to use an AED is part of every Life Safe CPR course. The skill takes minutes to learn and can be the difference between life and death. Read our step-by-step AED guide for more information.
What You Can Do: One Course, Lifetime Impact
The statistics paint a clear picture: Canada needs more people trained in CPR. Not healthcare professionals — regular people. Parents, coworkers, coaches, teachers, neighbours. The person most likely to be present during a cardiac arrest is someone who does not work in healthcare.
Getting trained takes one day. Keeping your skills sharp takes minutes a week with the Life Safe CPR Coach app. And the impact of that investment is measured in lives saved.
Frequently Asked Questions
What percentage of Canadians know CPR?
Studies indicate that fewer than 20 percent of Canadians feel confident they could perform effective CPR in an emergency. While a larger percentage have taken a CPR course at some point, skills degrade significantly without practice. Regular refresher training and at-home practice with tools like the Life Safe CPR Coach app help maintain readiness.
What is the survival rate for cardiac arrest in Canada?
According to the Heart & Stroke Foundation of Canada, the overall survival rate for out-of-hospital cardiac arrest is roughly 1 in 10. Survival varies by region, and in communities with high bystander CPR rates and rapid defibrillation it can be substantially higher. The single biggest factor in survival is whether someone nearby starts CPR immediately.
How many cardiac arrests happen outside hospitals in Canada each year?
The Heart & Stroke Foundation reports roughly 35,000 to 40,000 out-of-hospital cardiac arrests in Canada each year. The majority happen at home, which means the person most likely to be present is a family member, not a healthcare professional. This underscores why CPR training is not just for medical professionals — it is a skill every household needs.
Does bystander CPR really make a difference?
Yes — bystander CPR is one of the most impactful interventions in emergency medicine. The Heart & Stroke Foundation notes it can double or even triple the chance of survival by maintaining blood flow to the brain and heart until paramedics arrive. Without oxygen, brain damage begins within 4 to 6 minutes (Canadian Red Cross). Even imperfect CPR is far better than no CPR.
How often should I renew my CPR certification?
CPR certification in Canada is typically valid for three years. However, research shows CPR skills begin to decline within months of training. Life Safe recommends practising your skills regularly using the free CPR Coach app, which provides real-time feedback on your technique, and taking a recertification course before your certification expires.
