Ontario Heat Pump Rebate Registration Closes May 31 With Up to $12,000 Available

The Two Technology Categories

The program splits heat pumps into two broad categories, each with its own incentive structure. Cold-climate air-source heat pumps are described by the Home Renovation Savings program as units specifically designed to operate in temperatures as low as -30°C, making them suitable for most Ontario climates without supplemental fossil-fuel backup. Ground-source systems — also called geothermal — use the relatively stable temperature of the earth as their heat exchange medium and require either vertical boreholes or horizontal loops in the yard.

Both categories qualify for HRS rebates, but the dollar amounts diverge sharply. The program rewards the higher capital cost of geothermal with proportionally larger rebates, and rewards homes that depend on more expensive heating fuels with higher per-ton incentives across both technologies.

The Tiering: Gas Versus Non-Gas

The single most important variable in determining rebate value is whether the home is currently heated by natural gas. Households served by an Enbridge Gas residential gas furnace or boiler fall into the lower tier. Households heated by electricity, oil, propane, or wood fall into the higher tier.

The "per ton" measurement refers to the heat pump's minimum rated heating capacity at 8.3°C (47°F), which is the standard cold-climate sizing benchmark. Ground-source rebates for non-gas homes are calculated against closed-loop capacity. Our hub on how to properly size a heat pump for a Canadian home walks through what a 2-ton, 3-ton, or 4-ton system actually means in practical terms.

Renters and Rental Systems

Heat pump rentals are also covered. A homeowner who rents — rather than buys outright — a cold-climate air-source unit receives $500 per ton up to $2,000, and a flat $3,000 for a rented ground-source system. The rental option mirrors the lower gas-customer tier regardless of the home's existing heating fuel, which makes outright purchase the better economics for non-gas households when financing is available.

The Four-Step Process

The program's process is structured to lock in eligibility through the contractor, not through the installation date. The four steps run as follows:

1. The homeowner completes a short eligibility form on the HRS website and receives a list of participating HVAC contractors.
2. The homeowner selects a participating contractor, who helps choose the heat pump and submits a pre-installation application on the homeowner's behalf.
3. Once pre-installation approval is granted, the contractor proceeds with installation. Work started before pre-approval is ineligible — no exceptions.
4. After installation, the contractor submits a post-installation application. Once approved, the rebate cheque is mailed to the homeowner within roughly 60 days.

The second step is the registration that matters for the May 31 deadline. As long as a participating contractor has submitted a pre-installation application before the window closes, eligibility for the current rebate season is preserved. The installation can be scheduled into the summer or early fall as contractor availability allows.

Who Qualifies, In Brief

Eligibility is structured around home ownership, fuel type, and dwelling type. Applicants must own the home, with landlords applying on behalf of tenants. Eligible homes include single-detached, semi-detached, row and townhomes, and mobile homes on permanent foundations. New-build homes occupied for six months or less are excluded. Cornwall Electric customers are excluded unless their home is primarily heated by Enbridge natural gas. No home energy assessment is required for the heat pump category — a meaningful contrast with several federal retrofit programs that require pre- and post-EnerGuide evaluations.

Equipment must also be on the right list. Cold-climate air-source and water-to-air ground-source units must be active on Natural Resources Canada's qualified products lists, while water-to-water ground-source systems must appear on the ENERGY STAR Geothermal Heat Pump List and be available in Canada. Participating contractors will check product eligibility as part of the pre-installation application, but a homeowner who is browsing equipment specs ahead of time can save a step by confirming list status first.

The Greener Homes Loan as a Pairing

The HRS rebate offsets a meaningful share of the upfront cost. Federal financing covers the rest. The Canada Greener Homes Loan offers interest-free loans from $5,000 to $40,000, repayable over 10 years as an unsecured personal loan on approved credit. For a typical $20,000-$25,000 cold-climate ducted heat pump install, the combination — HRS rebate offsetting roughly a third of the project on the higher non-gas tier, Greener Homes Loan financing the balance interest-free — is what makes a heat pump cost-comparable to a furnace plus AC replacement on a 10-year horizon.

A note of caution on intake status: Natural Resources Canada's current program page indicates that available funding for the Greener Homes Loan has been fully allocated, even as the program structure remains documented. The intake situation may evolve, and homeowners exploring the stack should verify current availability before counting on it as a guaranteed financing path. We tracked the broader policy thread in our coverage of Carney's reaffirmation of the Greener Homes restart, which noted that homeowners are still waiting on funding flows to resume.

The pairing has a precedent worth knowing. A February 2024 update from Natural Resources Canada reported that about 45% of signed Greener Homes Loan agreements included financing for a heat pump, drawn from nearly 62,000 applications across Canada since the program's June 2022 launch. Heat pumps are not a peripheral use case for the loan — they are close to half of it.

Why the Non-Gas Tier Matters Most

The math on the higher tier is where the program's policy intent shows up clearly. A 3-ton cold-climate air-source heat pump installed in a non-gas home qualifies for $3,750 in rebate before any other consideration; on the gas-customer tier the same equipment qualifies for $1,500. The same 3-ton system in a non-gas household with ground-source qualifies for $6,000. The differential is structural, and it tracks closely with the populations Ontario has explicitly identified as bearing the highest heating costs — rural, Northern, and off-gas communities where oil, propane, and electric resistance heating dominate.

For households in those communities, the HRS rebate is not a marginal benefit. It is a meaningful change to the per-month cost of heating over the life of the equipment.

The action steps are short and specific. Homeowners considering a heat pump upgrade — or a like-for-like replacement of an aging furnace — should:

• Complete the HRS eligibility form on the program website to surface the list of participating contractors in their area.
• Book a consultation with a participating contractor before May 31 with the explicit purpose of submitting a pre-installation application. The contractor will need basic information about the home's current heating system, electrical service, and proposed equipment.
• Confirm that the proposed heat pump model appears on the relevant NRCan or ENERGY STAR qualified products list before any equipment is ordered.
• Hold off on signing installation paperwork or accepting equipment delivery until the pre-installation approval comes back.

For homeowners who are not ready to commit to a contractor, the eligibility form on its own is a no-cost step that surfaces who can submit on their behalf. The registration window is the binding constraint — once it closes, the next opportunity is a full season away.

The HRS program is not the only path to a heat pump in Ontario, but it is the most direct one available before the registration window closes. For households on the non-gas tier in particular, eleven days is the difference between a project that pencils out and one that waits another year.
