Ontario heat pump rebates: what each program pays and how to apply
Climate fit
Why heat pumps make sense in Ontario
Ontario's climate is classified as continental — cold winters and hot summers mean inverter-driven cold-climate heat pumps (CCHPs) are essential. Most homes here use natural gas, so heat pump installation typically pairs with a gas backup (dual-fuel) for sub-zero days.

What kind of heat pump fits Ontario's climate
What to look for
Cold-climate heat pumps (CCHP) with backup capacity for the coldest weeks. Most homes here run dual-fuel with the existing natural-gas furnace as backup below -15°C.
Minimum specifications
Minimum HSPF 10, SEER 16. Provincial rebates generally require a unit on a qualified-product list, so check the exact model before signing. Heat pump must maintain at least 70% rated capacity at -15°C.
What to avoid
Single-stage compressors. Inverter (variable-capacity) is the only sensible choice in continental climates — modulating from 30% to 100% output matches typical Canadian load patterns.
Conversion path
How Ontario homes typically convert to heat pumps
Most installations here keep the existing gas furnace as backup. A dual-fuel thermostat switches to gas below your "balance point" (typically -8°C to -15°C depending on heat pump sizing). You get electric heat-pump efficiency 80-90% of heating hours and gas only when the heat pump becomes uneconomical.
Gas-heavy provinces like Ontario have a more nuanced economics case. Natural gas is the cheapest fossil heating fuel in Canada by operating cost, so the savings come from offsetting cooling load (replacing AC) and from running the heat pump through the mild shoulder seasons. Dual-fuel installations keep the gas furnace as backup for the coldest days, and gas-heated homes qualify for smaller provincial rebates where any exist.
Timeline
How long the process takes in Ontario
Quotes typically come back within a day or two, and installation itself takes 1-3 days once scheduled. Where a provincial rebate requires an energy assessment before the work, book it before anything is installed.
None of it should happen in the dark. A good installer confirms each milestone as it passes — rebate paperwork submitted, audit booked, audit complete, loan approved, install scheduled, install complete, post-retrofit audit complete, final disbursement received. Silence between milestones is the most common early warning sign on a retrofit that is going wrong.

Find a qualified installer
This site is an independent guide. It does not sell or install heat pumps and does not provide quotes. The programs and directories below are where to find registered contractors and the rebate rules that apply in each province.
- National Heat Pump Rebate (Government of Canada)
The new federal rebate announced in October 2026: up to $10,000 below the median income and $2,000 for others, opening in early 2027. The official page has a sign-up for launch updates.
- Canada Greener Homes Affordability Program (NRCan)
No-cost heat pump and insulation retrofits for low- and median-income homeowners and tenants, applied for through the provincial partner. The federal Greener Homes Loan and Oil to Heat Pump Affordability program are closed.
- HRAI contractor directory
The Heating, Refrigeration and Air Conditioning Institute of Canada lists member HVAC contractors by region.
- Home Renovation Savings — Ontario
Ontario's rebate for cold-climate and ground-source heat pumps, paid per ton, and its qualified-product rules.
- Home Renovation Rebate — British Columbia
The BC Hydro and CleanBC rebate for heat pumps that replace electric heat, and the program rules that go with it.
- Efficiency Manitoba
Manitoba rebates for ducted and ductless cold-climate heat pumps.
- Efficiency Nova Scotia
Nova Scotia rebate programs and the approved-installer requirements that go with them.
Common questions
How much does a heat pump cost to install in Ontario?
Ducted air-source heat pumps in Ontario typically cost $12,000–$19,000 installed. Single-zone ductless systems run $4,000–$8,500. Home size, electrical service and existing ductwork move the number; the heat pump cost calculator adjusts for all three.
What rebates are available for heat pumps in Ontario?
Ontario homeowners can draw on up to $8,000 in grants and rebates. Programs that can apply in Ontario: Home Renovation Savings — cold-climate air-source heat pump ($1,250 per ton, up to $7,500), Home Renovation Savings — cold-climate air-source heat pump (gas-heated home) ($500 per ton, up to $2,000), Home Renovation Savings — ground-source heat pump ($2,000 per ton, up to $12,000), Home Renovation Savings — ground-source heat pump (gas-heated home) (up to $3,000). Separately, the federal National Heat Pump Rebate will add up to $10,000 for households below the median income, or $2,000 for others. It opens in early 2027 and covers eligible installs from November 1, 2026. The provincial rebate stacking guide explains how they combine.
Do heat pumps work in Ontario's climate?
Yes. Ontario's climate (continental) means cold winters and hot summers mean inverter-driven cold-climate heat pumps (CCHPs) are essential. Modern cold-climate heat pumps (CCHPs) are rated to operate at -30°C and below — well within Canadian-winter parameters.
How long does installation take in Ontario?
Most ducted retrofits in Ontario take 1-2 days. Ductless single-zone installations are typically 1 day. Multi-zone systems with 3+ indoor heads take 2-3 days. Geothermal is a larger project (5-10 days). Rebate paperwork adds 2-4 weeks for approvals but does not delay installation.
