As the new year begins, Ontario homeowners are being urged to check whether their homes are compliant with updated carbon monoxide safety rules now in effect under the Ontario Fire Code.
As of January 1, 2026, expanded requirements mean carbon monoxide alarms must be installed in any home with a fuel-burning appliance, fireplace, or attached garage. The rules also apply if fuel-burning equipment is located outside the home, such as in a detached utility shed.
To meet the new standard, working CO alarms are required on every storey of a home and outside all sleeping areas, even on floors without bedrooms.
Homeowners are responsible for compliance in their own residences, while landlords must ensure rental units meet the updated code.
When purchasing and installing alarms, residents are advised to choose units certified by CSA, ULC, or ETL and follow manufacturer instructions.
Fire officials encourage residents to verify compliance now, noting that properly installed alarms can save lives.
