Ontario Fire Code (O. Reg. 213/07) mandate expanded installation of carbon monoxide (CO) alarms in residential and care buildings. These changes aim to harmonize provincial law with the 2020 National Fire Code of Canada.
Updated Installation Requirements
If your home has a fuel-burning appliance (e.g., gas furnace, stove, fireplace), a wood-burning fireplace, or an attached garage, the following rules apply:
Mandatory on Every Level: You must have a CO alarm on every storey of your home, including basements and levels without bedrooms.
Sleeping Areas: Alarms remain mandatory adjacent to every sleeping area (typically in the hallway serving the bedrooms).
External Heating Sources: If your home is heated by air from a fuel-burning appliance located outside the dwelling (e.g., in a utility shed), alarms are now required.
Specific Building Applications
The 2026 code affects various housing types:
Houses & Townhomes: Must comply with the "every storey" rule.
Condos & Apartments: Alarms are required if the unit contains a fuel-burning appliance or shares a wall/ceiling with a garage or service room.
Public Corridors: Multi-unit buildings must have CO alarms in hallways if the corridor is heated by fuel-burning equipment.
Care Occupancies: New mandates apply to care facilities where residents may require assistance to evacuate.
Compliance and Standards
Alarm Types: Permitted devices include hardwired, plug-in, or battery-operated units.
Certification: Devices must be certified to standards such as CSA 6.19 or UL 2034.
Responsibility: Landlords and building owners are legally responsible for the purchase and installation of these alarms. Tenants are responsible for monthly testing and notifying landlords of malfunctions.
Penalties: Failure to comply can result in fines under the Fire Code, with Administrative Monetary Penalties (AMPs) now available for municipalities to enforce.
