Each house stands for one in ten of Saanich's 37,620 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.

Why it matters in Saanich

In the Victoria area, 37% of households heat mainly with electric baseboards, 23% with a heat pump and about 16% with a forced-air furnace; electricity is the main heating energy for 46% of households and natural gas for 23% (Statistics Canada, 2023).

The risk rises after air sealing: a tighter house plus a strong exhaust fan or dryer can pull exhaust back down a chimney. That's why advisors test for spillage during an evaluation and why it should be repeated after serious tightening.

The CO alarm rule in British Columbia

B.C. doesn't require CO alarms in existing homes; the province recommends them wherever there's a fuel-burning appliance, fireplace or attached garage, and the building code requires them in new homes.

What the check involves

  • Worst-case depressurization: exhaust fans and the dryer on, doors set to make the appliance room as negative as it gets.
  • A spillage and draft check at each appliance, with a CO reading.
  • A plan if anything fails: often a sealed-combustion appliance or a fix to the venting, done by a licensed gas or oil technician.
