Each house stands for one in ten of Vancouver's 115,455 houses (single-detached, semi-detached, row and duplex), drawn by when it was built. The glow shows the usual pattern: older houses tend to be leakier and less insulated. Snowfall scales with heating degree-days.

CO sources in Vancouver homes

In the Vancouver area, the main heating energy is natural gas for 42% of households (Statistics Canada, 2023). Any fuel-burning appliance, fireplace or attached garage is a potential CO source.

Single-detached houses make up 15% of Vancouver'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.
