Ontario Regulation 157/25: New AED Requirements Coming to Construction Sites - Is Your Company Ready?

New AED Construction Law In Ontario has Passed

Effective January 1, 2026, Ontario construction companies will face new life-saving requirements that could impact your operations and budget.

What is Ontario Regulation 157/25?

Ontario Regulation 157/25 is a groundbreaking amendment to O. Reg. 213/91 under the Occupational Health and Safety Act (OHSA) that mandates the presence of Automated External Defibrillators (AEDs) on specific construction projects across the province. This regulation represents a significant step forward in workplace safety, acknowledging that construction workers face elevated risks of cardiac events.

Why This Regulation Matters

The statistics are sobering: cardiac events, including sudden cardiac arrest, rank among the leading causes of workplace fatalities in Ontario. Construction workers face particularly heightened risks due to the physical demands and stressful nature of their work environment. However, there's hope in the numbers – when properly deployed, defibrillators can improve cardiac arrest survival rates by more than 50%.

When Does It Take Effect?

Mark your calendars: January 1, 2026 is the compliance deadline. While this may seem far away, smart companies are already beginning their preparation process to ensure seamless implementation.

Does This Apply to Your Company?

Ontario Regulation 157/25 applies to construction projects that meet both of the following criteria:

• 20 or more workers are regularly employed at the project
• The project is expected to last at least three months

If your construction projects meet these thresholds, you'll need to comply with the new AED requirements.

What the Regulation Requires

1. AED Equipment Standards

Your defibrillator must be licensed as a medical device by Health Canada. This ensures the device meets rigorous safety and effectiveness standards.

2. Required Accompanying Supplies

The regulation mandates that specific items be stored alongside each defibrillator:

• One cardiopulmonary resuscitation (CPR) mask
• One pair of scissors
• Two pairs of disposable medical-grade gloves
• One disposable razor
• One garbage bag
• Four absorbent towels

3. Storage Requirements

The AED and all accompanying items must be stored in a location that:

• Keeps all items together in one accessible place
• Protects equipment from dust, moisture, extreme temperatures, direct sunlight, and damaging substances
• Remains unobstructed for easy emergency access

4. Maintenance and Record-Keeping

Companies must:

• Maintain and test the defibrillator according to manufacturer specifications
• Conduct quarterly inspections
• Keep inspection records with the defibrillator at all times

5. Clear Signage

Proper signage must indicate the AED location using:

• A graphic symbol showing a heart with a lightning bolt
• The words "Automated External Defibrillator" or "AED"
• French equivalent text for bilingual compliance

6. Trained Personnel Requirements

At least one worker trained in both CPR and defibrillator operation must be present whenever work is in progress at the project site.

Financial Support Available

The Ontario government recognizes the financial impact of these new requirements. Bill 30, the Working for Workers Seven Act, 2025, proposes a reimbursement mechanism through the Workplace Safety and Insurance Board (WSIB) to help constructors offset AED-related costs. Eligible businesses may receive up to $2,300 in reimbursement.

Steps to Ensure Compliance

5. Design and order compliant signage
