Who’s coveredProjects that regularly have 20+ workers and are expected to last 3+ months must comply.


If you’re in scope, the constructor must ensure:


  1. AED + required emergency kit– Health Canada–licensed AED– Keep together with: 1 CPR mask, 1 pair of scissors, 2 pairs of medical-grade disposable gloves, 1 razor, 1 garbage bag, 4 absorbent towels.


  2. Storage conditions– AED and supplies stored in one place– Protected from dust, moisture, extreme temperatures, sunlight, and damaging substances– Unobstructed & easy to access.


  3. Maintenance & inspection– Maintain/test per manufacturer– Inspect at least quarterly and keep records on site.


  4. Signage– Clearly visible location signs– Must show the heart + lightning symbol and the words “Automated External Defibrillator,” “AED,” or the French equivalent.


  5. Trained personnel– At least one worker trained in CPR + AED on site whenever work is underway.

The regulation takes effect January 1, 2026. Non-compliance can trigger enforcement.
