Brampton at a glance
Climate
Brampton gets about 3,664 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 −18.3°C. Those figures come from the climate data for Toronto International in HOT2000, the home-energy software Natural Resources Canada (NRCan) gives energy advisors. A moderate heating season with warm summers: fixes should cut heating bills and keep the house cool.
Housing
Of Brampton's 155,800 houses (single-detached, semi-detached, row houses and duplexes), 3% were built before 1961 and 33% before 1991, according to the 2021 Census. The typical house dates from 2001–2005.
Heating
In the Toronto area, 59% of households heat mainly with a forced-air furnace, 8% with a boiler and radiators, 5% with electric baseboards and 4% with a heat pump; natural gas is the main heating energy for 52% of households and electricity for 18% (Statistics Canada, 2023).
Radon
In Health Canada's 2012 survey, none of the 89 homes tested in the Peel Regional Health Unit health region were above the guideline, a small sample that doesn't rule radon out. The larger 2024 Cross-Canada survey reports 4.5% (1 in 22) of houses at or above the guideline for Toronto Metro Area (Toronto CMA).

What homes in Brampton need
Cold winters and hot, humid summers: seal the attic, dry the basement, plan cooling.
This region has real winters and hot, humid summers, so bills come from both heating and cooling. Natural gas heats most Ontario homes, while most Quebec homes use low-cost electricity. An EnerGuide evaluation here should cover air sealing and the attic, cooling and dehumidification, and keeping the basement dry before insulating it.
In Brampton: Brampton sits just north of Pearson Airport, which set a daily rainfall record of 128.3 mm on August 17, 2024, so check grading, downspouts and the sump before finishing a basement. Summers are hot and humid, so size cooling carefully.
What drives bills and comfort here
- Both seasons cost money: winters are cold, and summers bring 37 to 74 days a year with a humidex of 30 or more.
- Gas heats 50% to 85% of homes in Ontario cities; in Quebec most homes use electric heat, and 16% already heat with heat pumps.
- Electricity costs about 8.3¢/kWh in Montreal versus 14.4¢ in Ottawa and 15.6¢ in Toronto (April 2025), which shapes heat-pump savings.
- Basement flooding is a growing cost: 2024 storms flooded basements from Toronto to Montreal, with insured losses in the billions.
Local risks to plan for
- July 2024 storms caused over $940 million in insured losses across southern Ontario.
- Cold snaps near −19°C; a variable-speed heat pump here needs backup heat.
- Radon: about 1 in 22 Toronto-area homes tested at or above the guideline in 2024.
What to check first, and why
-
Seal air leaks and top up the attic
Air sealing is still the first retrofit. In the snowier Ottawa–Montreal–Sherbrooke belt, a leaky, under-insulated attic also causes ice dams.
Ask your energy advisor: Ask for a blower door test and attic inspection, and whether old vermiculite insulation needs testing before any attic work.
Blower door testAttic inspectionAsbestos and vermiculite check
-
Right-size cooling to control humidity
In humid summers, an oversized air conditioner or heat pump cools quickly but shuts off before removing moisture, leaving rooms clammy. A heat pump replacing the air conditioner also covers much of the heating.
Ask your energy advisor: Ask for a room-by-room heat-loss calculation and a duct and airflow check before replacing your air conditioner or furnace.
-
Keep the basement dry before insulating
Basements can be about 20% of heat loss, but insulating a damp basement from the inside can rot the new wall. Flash floods have hit Toronto and Montreal repeatedly.
Ask your energy advisor: Ask the advisor to check grading, downspouts, foundation cracks and the sump, and to look for damp spots or white mineral stains.
-
Test for radon
About 1 in 6 homes in the Ottawa–Gatineau and Montreal areas tested at or above Health Canada's guideline in the 2024 survey; Kingston and Sherbrooke ranked among the highest municipalities.
Ask your energy advisor: Run a 3-month test in the heating season, and retest after air sealing or basement work.
-
Plan backup heat for power outages
Recent ice storms and the May 2022 derecho windstorm each left hundreds of thousands of customers without power. Every heat-pump plan needs backup heat and a safe way through an outage.
Ask your energy advisor: Ask how your home would stay warm in an outage, and keep baseboards or the furnace as backup when adding a heat pump.
Tests that matter most here
- Blower door test Measures leakage (ACH50) and, with a thermal scan, finds where air gets in. Best timing: Any season; pair it with a thermal scan in winter.
- Infrared (thermal) scan Shows missing insulation and air leaks as cold spots. Best timing: December to February, early morning or on an overcast day, with at least 10°C between inside and outside.
- Heat-loss calculation Prevents oversized equipment that short-cycles and dehumidifies poorly, and is needed to choose the right heat pump. Best timing: Before replacing an air conditioner or furnace, based on the house after planned upgrades.
- Radon test Moderate to high regional radon, and upgrades can change indoor levels. Best timing: At least 91 days, mostly in the heating season; retest after upgrades.
- Combustion safety test In gas-heated homes, tightening can cause spillage from older furnaces and water heaters. Best timing: During the blower door visit.
Upgrades that usually pay off here
- Air sealing plus attic insulation. Usually the best envelope payback. Today's new-home attic minimum here is about R-49, a good target for older homes. Don't disturb old vermiculite insulation until it's tested for asbestos.
- Heat pump instead of a new air conditioner. One machine gives efficient cooling and most of the heating. In Ontario it often pairs with the gas furnace; in Quebec, baseboards can stay as backup. Choose a cold-climate model in colder cities such as Ottawa, Montreal and Sherbrooke.
- Basement insulation, once it's dry. A large heat-loss area. Fix water entry first, then insulate.
- Covered sump and better drainage. NRCan lists a covered sump among basement moisture fixes. Extending downspouts and sloping soil away from the house help keep storm water out.
- ERV for balanced ventilation. Brings in fresh air while recovering heat; NRCan suggests ERVs where cooling loads are high, as they are here.
Heating and cooling equipment
- In colder cities such as Ottawa, Montreal and Sherbrooke, choose a cold-climate heat pump. Along Lakes Erie and Ontario, good variable-speed units cover most hours, with backup heat.
- When a heat pump replaces the air conditioner, size it to balance heating and cooling; NRCan's guide caps cooling capacity at about 125% of the cooling load.
- Electric backup (baseboards or strips) can run with the heat pump; a furnace in a hybrid system takes over instead of running at the same time.
- For dehumidification, run the indoor fan on low in cooling mode, and size equipment so it runs long cycles.
Health and comfort
- Damp basements: run a dehumidifier in summer, and keep indoor relative humidity below about 40% in cold weather to avoid condensation and mould.
- Wildfire smoke can travel far: Ottawa's fine-particle level hit 511 on June 7, 2023 (normal is 4 to 11), and Montreal briefly had the world's worst air that month.
- Heat: Ottawa reached a humidex of 47 in the 2018 Canada Day heat wave. Make sure at least one room can be kept cool.
- Radon: about 1 in 6 homes across Central Canada tested at or above 200 Bq/m³ in the 2024 survey, though only about 1 in 22 in the Toronto area.
Common mistakes in this climate
- Insulating a damp basement from the inside. Trapped moisture rots the new wall and feeds mould. Fix drainage and leaks first.
- An oversized air conditioner or heat pump. It short-cycles, removes less humidity and wears out faster.
- Tightening a gas-heated home without a safety test. Older gas appliances can spill exhaust into a tighter house. Ask for a combustion safety test.
- Leaving hybrid controls on factory settings. The switchover between heat pump and furnace should match your gas and electricity prices. Ask how it's set.
When to book: Book the evaluation in winter (December to February) for clear thermal scans, and start a 3-month radon test in fall. Check the basement after spring thaw or heavy rain, and line up cooling work before summer.
