What Actually Changed in the 2026 Ontario Fire Code (And Why)

Ontario's fire code changed on January 1, 2026, and the updates affect most condominium corporations in some way. Some requirements are entirely new, while others raise the standard for inspections, testing, and recordkeeping. Many of these changes were prompted by lessons learned from actual fire and carbon monoxide incidents, while others align Ontario's rules more closely with the National Fire Code of Canada. Here are the updates condo boards and property managers should know.

Carbon monoxide detection is now much broader

CO alarms used to be required mainly near sleeping areas in units with gas appliances or attached garages. The updated rules expand that significantly. Buildings with gas fired makeup air units now need CO detection in hallways at intervals of no more than 25 metres, and units heated by fuel burning equipment located elsewhere in the building may now require alarms as well. The Ontario Association of Fire Chiefs has a useful summary of exactly where alarms are now required.

Fire alarm testing is far more rigorous

Annual fire alarm inspections must now follow the CAN/ULC S536 and S537 standards. This means your fire contractor can no longer simply confirm the system works and move on. Deficiencies must be documented separately, attendance logs are required, and battery testing now includes functional load testing rather than a basic voltage check. According to industry association ACMO, inspection reports are now considered official regulatory documents, and inspections themselves may take significantly longer as a result. If you have not already asked your fire contractor whether their reporting meets S536 and S537, that is a good first call to make.

A new integrated testing requirement: CAN/ULC S1001

This is the change fewest condo boards seem to know about. Traditionally, fire alarm, sprinkler, and other life safety systems were tested individually. CAN/ULC S1001 introduces integrated system testing, essentially simulating a real fire event to confirm that all systems actually communicate and respond together, not just in isolation. It applies to all new construction and is now also triggered by major work on existing buildings, including fire panel replacements, sprinkler upgrades, or new access control hardware like maglocks. For most condos, this becomes a five year recurring requirement.

Exit doors and access hardware fall under new scrutiny

All exit doors in residential buildings, not just designated fire doors, must now meet fire code standards for locking, latching, and fastening, and must be operable from the inside without special knowledge or tools. This is a low-cost, high-value item for managers: a simple walk-through of your building checking that doors close and latch properly can catch issues before an inspector does.

Perhaps the most consequential shift is enforcement. Municipalities can now issue fines directly through Administrative Monetary Penalties, without the case first going through the courts. That makes penalties faster and harder to avoid. Fines can reach up to $500,000 for a corporation on a first offence, and individuals, including board directors, can face fines of up to $50,000. Property management companies have also been named alongside boards in past enforcement cases.

What this means for your corporation

Every condominium corporation has routine responsibilities that can easily slip into the background, and fire code compliance is often one of them. The 2026 amendments are a good reason to revisit your fire safety plan, testing records, and maintenance procedures. A review now can identify small issues before they become expensive ones, and it helps ensure your building is prepared for both inspections and emergencies.
