Starting January 1, 2026, new provincial safety regulations will expand carbon monoxide (CO) alarm requirements in existing homes across Ontario. The change aims to protect residents from carbon monoxide — an invisible, odourless, and potentially deadly gas that can result from fuel-burning appliances or attached garages.
Under the updated Fire Code, homeowners must install working CO alarms in two key locations: adjacent to each sleeping area and, as of 2026, on every storey of the home — including those without bedrooms. The rules apply to all homes with fuel-burning appliances, fireplaces, or attached garages, as well as those receiving air for heating from an external fuel-burning source.
Landlords are responsible for compliance in rental properties, while homeowners must ensure their own homes meet the new standards. CO alarms can be hardwired, battery-operated, or plug-in models, and must display certification from recognized testing agencies such as CSA, ULC, or ETL.
Officials remind residents that installing and maintaining CO alarms is not just a legal requirement — it’s a lifesaving measure. For clarification or local enforcement details, contact your municipal fire department.
