The rule in Prince Edward Island
PEI's Fire Marshal advises CO alarms outside each sleeping area and on every level, but we found no rule requiring them in existing homes.
CO sources in Charlottetown homes
In Prince Edward Island, the main heating energy is oil for 28% and wood for 8% of households (Statistics Canada, 2023). Any fuel-burning appliance, fireplace or attached garage is a potential CO source.
There's no piped natural gas for homes in Charlottetown, so the usual CO sources are oil furnaces, propane appliances, wood stoves and attached garages.
Single-detached houses make up 44% of Charlottetown'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.
