The short version

Most people asking “how long is a CPR course” are really asking one of two things: how much time do I need to block off this weekend or which course fits the requirement my employer gave me. Here’s the answer to both at once.

Course Total time Format Best for
CPR C AED ~4 hours Half-day, single session General public, parents, gym staff
Emergency First Aid + CPR C 6.5–8 hours One full day Small workplaces (1–5 workers)
Standard First Aid + CPR C ~14 hours Two consecutive days Workplaces of 6+, daycare staff, the most common cert
BLS (Basic Life Support) 4–6 hours Single session Nurses, paramedics, dentists, healthcare students
Standard First Aid Recert ~8 hours One day Renewing an unexpired card
BLS Renewal 3–4 hours Half-day Healthcare workers renewing annually

Why CPR Level C is the shortest

CPR Level C focuses on one skill set: chest compressions, rescue breaths, AED use, and choking response — for adults, children, and infants. It doesn’t include the broader first aid material on bleeding, burns, fractures, seizures, or environmental injuries. Four hours is enough to teach the technique, let everyone practise on a manikin, and run the practical assessment.

Life Safe’s CPR C AED course is $35 and runs every week across our Ontario locations.

Why Standard First Aid is two days

Standard First Aid covers everything in CPR Level C, plus a wide range of first aid scenarios — wound care, broken bones, head and spine injuries, medical emergencies (heart attack, stroke, diabetes), poisoning, environmental injuries (heat, cold, drowning), and how to manage a casualty until EMS arrives. There’s a lot of content, and most of it requires hands-on practice.

Splitting it over two days gives your brain a chance to consolidate the material overnight. Some providers offer it as one long day, but the two-day format is the most common.

Why BLS is short but intense

BLS is the version of CPR used by healthcare professionals. It assumes you already understand the anatomy and physiology and focuses on high-performance technique: depth and rate of compressions measured precisely, two-rescuer coordination, ventilation with a bag-valve-mask, and integration with an AED. It’s shorter than a public CPR course but more demanding.

What about online courses?

You can complete an online-only CPR course in 1 to 2 hours. The catch: it can’t certify you for any workplace that follows Ontario Regulation 1101, because WSIB approval requires hands-on assessment with a qualified instructor.

Blended courses are a good middle ground. You do the theory online at your own pace (usually 2–4 hours), then attend a shorter in-person practical session (3–4 hours) for skills assessment. The certificate is fully WSIB-approved.

How to choose

If your employer told you a specific course name, follow that. If you’re picking for yourself, the two most common answers are:

  • Just want CPR for personal preparedness? Take the 4-hour CPR Level C.
  • Need it for a workplace? Almost certainly Standard First Aid with CPR C (the two-day course).
