Heat Pump Rebates in Ontario: Why Gas Homes Get Less (and What You Can Claim)

Ontario’s headline heat pump rebate is up to $12,000, but that number hides the detail that decides most claims: what heats your home today.

Under Home Renovation Savings, a home heated by electricity, oil, propane, or wood can claim much more than an Enbridge gas home adding a heat pump beside its furnace. Here is the full rate card, the examples that matter, and the approval step homeowners most often get wrong.

The Ontario rebate rate card

Home Renovation Savings is delivered by Enbridge Gas and Ontario’s Independent Electricity System Operator. The heat pump stream does not require a home energy assessment, but it does require program approval before installation.

If you buy the heat pump

For an air source system, the tonnage is based on its minimum rated heating capacity at 8.3°C. For a ground source system, it is based on closed loop capacity. Your contractor should show you the rated capacity for the exact model being quoted, because the number on a sales brochure is not always the number the program uses.

If you rent the heat pump

Rentals use a separate rate:

Do not add the rental and purchase amounts together. One installation gets one treatment.

What the rates mean on a real quote

Capacity changes the cheque. These examples use the program calculation before any future federal rebate is added:

That is why two neighbours can install similar equipment and receive very different rebates. The Ontario program is not simply paying for the machine. It is paying more where the heat pump displaces a more expensive or emissions intensive primary heating system, and less where a gas furnace remains part of the main heating setup.

Who can claim it?

You generally need to meet all of these conditions:

• You own the home where the heat pump will be installed. If the home has tenants, the owner applies.
• You either have an active Enbridge Gas residential account and primarily heat with a natural gas furnace or boiler, or you are connected to Ontario’s electricity grid and primarily heat with electricity, oil, propane, or wood.
• The property is a detached, semi detached, row house, townhome, or mobile home on a permanent foundation.
• The home has been occupied for more than six months. New builds do not qualify.
• The exact equipment is eligible. Cold climate air source models and most ground source models must appear on the applicable Natural Resources Canada qualified product list, and water to water ground source models must meet the program’s ENERGY STAR list requirement.
• A participating HVAC contractor handles the required program applications.

Cornwall Electric customers are a special exception because Cornwall is supplied through the Hydro Québec grid. They cannot qualify through the electricity route unless the home is primarily heated by Enbridge natural gas.

The approval rule that can erase the rebate

This is the step to get right:

1. Complete the program’s short eligibility form.
2. Choose a participating HVAC contractor.
3. Let the contractor submit the pre installation application.
4. Wait for approval before the heat pump is installed.
5. After installation, the contractor submits the post installation application.
6. Once that application is approved, the program says the cheque should arrive by mail within 60 days.

Pre approval is mandatory. An installation completed before approval is not eligible, even if the home and equipment would otherwise qualify. A signed equipment quote is not the same thing as program approval, so ask the contractor to show you the approval before work begins.

How the coming federal rebate could stack

Ottawa’s National Heat Pump Rebate is scheduled to open in early 2027 and is designed to stack with provincial programs. Ottawa has announced up to $10,000 for households below the provincial median income and $2,000 at the standard tier.

For illustration, an electrically heated Ontario home installing a 4 ton air source heat pump could pair:

• $5,000 from Ontario today
• $2,000 to $10,000 from the future federal program, if the household and installation qualify under its final rules
• $7,000 to $15,000 in combined support

Do not treat that combined range as a promise yet. The federal portal, final application rules, and program interactions have not been published. The safe Ontario strategy is to protect the provincial rebate you can claim now, keep every approval and invoice, and read the federal fine print before assuming the two programs will pay in full on the same installation. Our master stacking table tracks the current national picture.

Ontario buying advice

• Gas heated homes: compare the smaller rebate against the value of keeping the furnace as backup. A hybrid system can still make sense, especially if the existing air conditioner also needs replacement. Run the full ownership math in our heat pump vs furnace comparison.
• Electric, oil, and propane heated homes: your provincial rebate is large enough to change the equipment decision. Get quotes for both air source and ground source before defaulting to the cheaper install.
• Every home: get the eligible model number, rated capacity, rebate calculation, and approval responsibility in writing. The lowest equipment quote is not a bargain if it quietly loses a four figure rebate.

Ontario’s program rewards the homework. Know your heating fuel category before you shop, because in this province that one answer can move the rebate by more than $5,000.
