How Whitehorse is built

Whitehorse's houses by when they were built Ten house shapes, one for each tenth of Whitehorse's 9,485 houses. Before 1961: 8%, 1961–1990: 41%, 1991–2000: 16%, 2001 or later: 35%. Older houses glow hotter.
  • Before 1961 8%

  • 2001 or later 35%
Each house stands for one in ten of Whitehorse's 9,485 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. More snow in the drawing means more heating degree-days: a longer, colder heating season.

Whitehorse at a glance

Climate

Whitehorse gets about 6,522 heating degree-days a year, a measure of how much heating its climate needs, and its winter design temperature, the cold day heating systems are sized for, is −36.4°C. Those figures come from the climate data for Whitehorse in HOT2000, the home-energy software Natural Resources Canada (NRCan) gives energy advisors. Very cold winters: heating dominates, and a heat pump needs cold-climate ratings and backup heat.

Housing

Of Whitehorse's 9,485 houses (single-detached, semi-detached, row houses and duplexes), 8% were built before 1961 and 48% before 1991, according to the 2021 Census. The typical house dates from 1991–1995.

Radon

Health Canada's 2012 survey found 19.6% of 225 homes tested in the Yukon health region above the guideline. The larger 2024 Cross-Canada survey reports 27.8% (1 in 4) of houses at or above the guideline for Whitehorse, YK (Whitehorse census agglomeration).

The North Yukon, NWT and Nunavut

What homes in Whitehorse need

Extreme cold and costly energy: envelope first, reliable heat, safe oil tanks, permafrost.

The North has the longest, coldest winters we cover, with temperatures that reach −41°C. About half of Yukon homes heat with oil, and electricity costs more than in southern cities, so every bit of heat kept in saves real money. An EnerGuide evaluation here should put the building envelope first, then check heating reliability, oil tank safety, ventilation and humidity limits, and signs of permafrost movement.

In Whitehorse: Whitehorse has cold snaps to −41°C and permafrost under parts of the area, which Yukon University has mapped for thaw sensitivity. Electricity costs about 26¢/kWh and oil heats about half of Yukon homes, so envelope upgrades come first.

What drives bills and comfort here

  • The longest, coldest heating season we cover: cold snaps reach −41°C in both Whitehorse and Yellowknife.
  • Oil heats about half of Yukon homes, and heating oil averaged about $2.25 to $2.28 a litre in Whitehorse and Yellowknife in September 2026.
  • Electricity is expensive: about 26¢/kWh in Whitehorse, and well over 30¢ in Yellowknife once extra charges are added (2026).
  • Yukon's grid is mostly hydro, but liquefied natural gas and diesel cover winter peaks, so deep-winter heat-pump use partly runs on fossil power.

Local risks to plan for

  • −44.8°C in early January 2022, the coldest in almost 17 years.
  • About 28 days a year with wind chill below −30.
  • Permafrost underlies 10% to 50% of the ground; thaw can crack walls and shift tanks.
  • Radon: the 2024 survey listed Whitehorse among Canada's 18 highest municipalities.

What to check first, and why

  1. Envelope first: seal, insulate, upgrade windows

    With the coldest winters we cover and costly fuel, envelope work saves more than equipment changes. Today's new-home minimums here, about R-59 attics and R-22 walls, are good targets.

    Ask your energy advisor: Ask for a blower door test with a thermal scan, and a list of envelope upgrades ranked by savings.

  2. Keep heat reliable and oil tanks safe

    Oil is the main fuel, and losing heat at −40°C is serious. Permafrost movement can tilt oil tanks and strain fuel lines.

    Ask your energy advisor: Ask the advisor to check the burner, venting and CO alarms, and to look for a leaning tank or bent supply line.

  3. Ventilate within humidity limits

    A tight house needs fresh air, but at −40°C indoor relative humidity must stay very low, about 12% to 20% depending on the windows, to avoid frost and condensation.

    Ask your energy advisor: Ask for a ventilation assessment, and an HRV or ERV with frost protection.

  4. Watch for permafrost movement

    Whitehorse sits where permafrost underlies 10% to 50% of the ground, and Yellowknife-area homes can sit on thaw-sensitive patches. Thaw can crack walls and jam doors.

    Ask your energy advisor: Ask the advisor to note sticking doors, new cracks or sloping floors, and call an engineer if the house is moving.

  5. Test for radon

    Whitehorse ranked among the highest municipalities in the 2024 national survey, and about 1 in 4 Yukon homes tested at or above Health Canada's guideline.

    Ask your energy advisor: Run a 3-month test in the heating season, and retest after air sealing.

    Radon test

Tests that matter most here

  • Blower door test The biggest savings come from finding and sealing leaks; it measures ACH50 before and after. Best timing: October to April, avoiding strong wind.
  • Infrared (thermal) scan Deep cold makes insulation gaps and air leaks stand out clearly. Best timing: October to April, almost any day; avoid strong wind and sun on the walls being scanned.
  • Combustion safety test Oil and propane heat many homes, and a tighter house can cause backdrafting. Best timing: With the blower door visit.
  • Ventilation assessment Checks that fresh air reaches a tight house without pushing indoor humidity past what the windows can handle. Best timing: In mid-winter, when humidity limits are tightest.
  • Radon test High radon in Yukon. Best timing: At least 91 days in the heating season.

Upgrades that usually pay off here

  1. Air sealing and insulation to northern levels. The biggest savings anywhere we cover: the highest heating demand, paid for with costly oil and power. Seal first, then insulate attics, walls and rim joists.
  2. Efficient heating with full backup. A high-efficiency oil, propane or pellet system, or a cold-climate heat pump with full backup where power is mostly hydro. Air-source heat pumps can't carry the coldest weather here.
  3. HRV with frost protection. Brings in fresh air without throwing away heat in a tight house.
  4. Energy-efficient windows. Cut heat loss and let you keep a little more indoor humidity before windows frost.

Heating and cooling equipment

  • Air-source heat pumps need a full-size backup here: in NRCan's subarctic zone, only about 45% of the yearly heating load comes at −9.4°C or warmer.
  • Cold-climate air-source heat pumps are rated to about −30°C, while cold snaps here reach −41°C.
  • An ERV suits homes where indoor air runs very dry, as it does in northern winters; whichever you choose, it needs frost protection.
  • Keep CO alarms near every fuel-burning appliance, and have oil burners serviced before winter.

Health and comfort

  • Radon: about 1 in 4 Yukon homes and about 1 in 5 NWT homes tested at or above 200 Bq/m³ in the 2024 survey. Test every home.
  • Wildfire smoke and evacuation: about 20,000 people left Yellowknife and nearby communities for almost three weeks in August 2023. Have filtration ready for smoky days.
  • Extreme cold: Whitehorse fell to −44.8°C in January 2022. Protect pipes, and have a plan if the heat goes out.
  • Very dry indoor air: humidify only within window-condensation limits, or frost and moisture build up on windows and in walls.

Common mistakes in this climate

  • Banking snow or water against the foundation. It warms the ground and can thaw permafrost under the house. Keep snow and drainage away from the foundation.
  • An air-source heat pump without full backup. It can't carry the coldest weather here.
  • Leaving oil tanks and lines unchecked. Ground movement can tilt tanks and bend supply hoses; check them every season.
  • Air sealing without ventilation and safety checks. A tight house needs fresh air and a combustion safety test so appliances vent safely.

When to book: Book the evaluation between October and April, when the cold makes leaks easy to find. Start a 3-month radon test in the heating season, and check the foundation in late summer, when thaw is deepest.
