New Year, New Requirements: What the 2026 Ontario Fire Code Changes Mean for You
As of January 1, 2026, several updates to the Ontario Fire Code officially came into effect. These changes introduce revised inspection formats, stricter documentation requirements, expanded testing procedures, and enhanced safety standards that impact nearly every building across the province.
If you’re a building owner, property manager, facility operator, or homeowner, understanding these updates is essential for staying compliant and avoiding unexpected delays or enforcement issues.
The 2026 Ontario Fire Code updates are designed to better reflect modern buildings, evolving technologies, and increased safety expectations. Ontario is also aligning more closely with the 2020 National Fire Code of Canada, creating greater consistency across jurisdictions.
What Are the 2026 Fire Code Changes Designed to Do?
The updated Fire Code requirements aim to:
Improve early detection of fire and carbon monoxide
Strengthen inspection, testing, and documentation standards
Increase safety in modern and complex buildings
Improve enforcement and overall compliance
Harmonize Ontario’s Fire Code with the National Fire Code of Canada
These changes directly affect how systems are installed, tested, inspected, and maintained.
A Major Change: Expanded Carbon Monoxide (CO) Alarm Requirements
One of the most significant 2026 updates relates to carbon monoxide alarm placement in existing homes.
Under the updated Ontario Fire Code, CO alarms are now required in more residential settings, including:
Detached homes
Semi-detached homes
Townhouses
Cottages
CO Alarms Are Required If Your Home Has Any of the Following:
A fuel-burning appliance (natural gas, propane, oil, or wood)
A fireplace
An attached garage
Air supplied from a fuel-burning appliance located outside the home (such as a utility shed)
Where CO Alarms Must Be Installed:
If your home meets any of the above conditions, CO alarms must be installed:
Adjacent to each sleeping area (near all bedrooms)
On every storey of the home, including levels without bedrooms
These requirements were introduced through O. Reg. 87/25: Fire Code and align with recent updates to the Ontario Building Code, including requirements for existing residential and care occupancies.
