The rule in Quebec
Quebec has no province-wide rule requiring CO alarms in existing houses: provincial rules cover larger multi-unit buildings, and for houses it's up to each municipality's by-law, so ask your local fire service.
CO sources in Québec City homes
Single-detached houses make up 30% of Québec City's households; many have an attached garage, another reason to put an alarm near the door into the house.
What a CO check involves
- Alarms next to sleeping areas and on every storey, tested monthly and replaced by their end-of-life date (usually 7 to 10 years).
- Annual service of fuel-burning appliances by a licensed technician.
- A combustion spillage test during an energy evaluation, which catches a venting problem before it produces CO.
