Short answer: yes, in Calgary you can perform CPR on a stranger even if your first aid certification has expired or you have no certification at all. Alberta’s Emergency Medical Aid Act gives you civil liability protection for good-faith emergency response. But the legal picture changes if you’re a designated workplace first aid attendant or a healthcare professional. This guide explains the difference.
The Alberta Emergency Medical Aid Act (Good Samaritan Law)
Alberta’s Good Samaritan legislation is the Emergency Medical Aid Act. Under Section 2, no person who provides emergency medical assistance to an ill, injured, or unconscious person is liable for damages arising from any act or omission during that assistance, provided:
- The assistance is provided in good faith
- The person is not grossly negligent
- The person is not compensated for providing the aid at that scene
This protection applies to every person in Alberta — certified or not, expired certification or not, medical background or none. The legislature intentionally cast the net wide to encourage bystander response.
Bystander CPR — No Certification Required, Ever
You do not need any first aid or CPR certification to perform bystander CPR at the scene of a cardiac emergency in Calgary. In fact, Alberta Health Services actively encourages bystander CPR because:
- Sudden cardiac arrest survival drops by 7–10% for every minute without CPR
- Bystander CPR before EMS arrival roughly doubles or triples survival odds
- Even chest-compression-only CPR (no rescue breaths) is highly effective for adult cardiac arrest and safer for untrained rescuers
Calgary 911 dispatchers are trained to coach untrained callers through CPR while EMS is en route. Follow their instructions.
Where Certification Actually Matters
Certification requirements apply to specific roles, not to bystander response:
Workplace First Aid Attendant
Alberta’s First Aid Regulation requires designated workplace attendants to hold current certification appropriate for the hazard rating and distance from medical services. If your certificate has expired, you cannot be designated as the workplace attendant — but you can still perform CPR as a co-worker responder under Good Samaritan protection.
Healthcare Professionals
Nurses, doctors, paramedics, and other regulated professionals have profession-specific standards of practice that apply even off-duty in some circumstances. See our companion post on whether Calgary nurses are obligated to perform CPR.
Paid Emergency Responders
Firefighters, EMTs, paramedics, and lifeguards on duty have a legal duty to respond. Good Samaritan protection typically does not apply to their compensated on-duty acts — they are held to professional standards.
What “Gross Negligence” Actually Means
The Good Samaritan protection has one important carve-out: it does not protect you if you are “grossly negligent.” This is a high bar. Gross negligence means willful or wanton disregard for the safety of others — not simply making a mistake under pressure. Examples of what does NOT count as gross negligence:
- Ineffective chest compressions from lack of training
- Breaking ribs during compressions (this is common and expected in effective CPR)
- Getting the compression rate slightly wrong
- Failing to check pulse before starting
What could count as gross negligence: refusing to yield to a certified responder who arrives, deliberately harming the patient, or acting under obvious intoxication.
Do Chest-Compression-Only CPR if You’re Unsure
Current Canadian guidance (Heart & Stroke Foundation, AHS) supports hands-only CPR for untrained or uncertain bystanders in adult cardiac arrest:
- Push hard and fast in the centre of the chest
- Rate: 100–120 compressions per minute (roughly to the beat of “Stayin’ Alive”)
- Depth: 5–6 cm (2–2.4 inches) for adults
- Full recoil between compressions
- Minimise interruptions
- Continue until EMS arrives, an AED is applied, or signs of life return
You are not required to give rescue breaths as a bystander — hands-only CPR is effective for the first several minutes and safer for the rescuer.
Should You Renew Your First Aid Anyway?
Even though bystander CPR is legally protected without certification, renewing your certificate has practical benefits:
- You’ll actually know what to do — muscle memory matters when adrenaline is high
- Your workplace probably requires it for your specific role
- Recent training gives you confidence to start early rather than waiting for EMS
See our companion post on first aid certification expiry in Calgary for renewal options.
What Calgary 911 Wants Bystanders to Do
- Call 911 immediately, or have someone else call while you assess
- State the location clearly (address, cross street, floor, room)
- Confirm the patient is unresponsive and not breathing normally
- Ask about the nearest AED — Calgary has thousands of public AEDs registered with AHS
- Start compressions if the patient is unresponsive and not breathing normally
- Follow the dispatcher’s instructions — they are trained to coach compression rate and depth
- Continue until EMS arrives or a trained responder takes over
Frequently Asked Questions
Can I do CPR in Calgary without any first aid certification?
Yes. Alberta’s Emergency Medical Aid Act protects any person who provides emergency assistance in good faith. No certification is required for bystander CPR.
Am I legally protected if my first aid certification expired and I do CPR?
Yes. The Emergency Medical Aid Act applies regardless of certification status. Protection covers bystanders acting in good faith without gross negligence.
What if I hurt the person while doing CPR?
Breaking ribs is common during effective CPR and does not count as gross negligence. Good Samaritan protection covers unintended harm from good-faith emergency assistance.
Do I need to give rescue breaths, or is chest-compression-only CPR OK?
Hands-only CPR is officially recommended for untrained bystanders and highly effective for adult cardiac arrest for the first several minutes. Compressions matter most.
Does Good Samaritan protection apply to a doctor or nurse off-duty?
Yes for good-faith emergency assistance outside their scope of employment. However, healthcare professionals may have profession-specific standards that apply even off-duty — see our nurse CPR obligation post.
Can I be sued if I do CPR badly and the person still dies?
Not under Alberta’s Emergency Medical Aid Act, provided you acted in good faith and were not grossly negligent. The legislation exists precisely to remove this fear as a barrier to bystander response.
Should I still renew my first aid certification if bystander CPR is legally protected?
Yes. Legal protection doesn’t mean you know how to perform effective CPR. Renewed certification gives you skill and confidence. It is also required for workplace first aid attendant designation.
