Carbon Monoxide Rules — What Ontario Homeowners Need to Know in 2026

As of January 1, 2026, Ontario has expanded carbon monoxide alarm requirements under the Fire Code. These changes apply to homeowners, landlords, tenants, and condo owners.

CO alarms are now required on every storey of a home, not just near bedrooms, if fuel-burning equipment, fireplaces, or attached garages are present. The goal is earlier detection and safer outcomes.

For multi-unit buildings, requirements extend to units near service rooms or garages and to corridors heated by fuel-burning systems.

These changes are not about compliance paperwork. They are about safety and awareness. Carbon monoxide is odourless and invisible. Early warning saves lives.

Understanding these updates is essential whether you own, rent, or manage property.
