Official sources checked on November 13, 2026.
The smart thermostat rebate Ontario homeowners can claim in 2026 is listed at $125 per household on the Home Renovation Savings program website (November 2026), paid either as an instant discount code at checkout or as a rebate you claim with your receipt within 60 days of purchase. To qualify, you must heat with an Enbridge Gas furnace or boiler, or heat or cool electrically on the Ontario grid, live in a detached, semi-detached, row or mobile home (condos are excluded), and buy, install and activate an eligible model by December 31, 2026. One catch: the program’s written terms (version January 2026) still state $100, with $125 reserved for Energy Affordability Program kit recipients, so keep proof of the amount you were offered.

How much is the smart thermostat rebate in Ontario: $125 or $100?
The program advertises $125, while its written terms still list a $100 base rebate. The program’s smart thermostat page and home page show $125 (the old $100 is struck through on the home page), and both application routes on that page say “$125”.
The two legal documents on the program’s terms and conditions page (Instant and Post-Purchase terms, both marked “Version date January 2026”) still set the base rebate at $100. A footnote raises it to $125 for customers who received a free energy saving kit through Save on Energy’s Energy Affordability Program, with eligibility “determined by IESO in its sole discretion”.
- What it means for you: check the amount in the application or discount offer before you buy. If the amount differs from the program website, contact program support to confirm what applies to you.
- Protect yourself: take a screenshot of the amount shown when you request your code or submit your receipt. If you are paid $100, call the program support line at 1-866-449-8510 and quote the website amount.
- Pages that quote “$100” may be citing the base amount in the terms rather than the current website offer.
If you received an Energy Affordability Program kit, our guide to the Energy Affordability Program in Ontario explains the income limits and the free upgrades that come with it.
Who qualifies for the rebate
You qualify if you meet all three conditions listed on the official page, and your thermostat will control your main heating or cooling.
- Energy account and heating type. Either you are an Enbridge Gas customer with an active account who primarily heats with a natural gas furnace or boiler, or you are connected to the Ontario electricity grid and heat or cool your home electrically. Cornwall Electric customers are not eligible because they are on the Hydro-Québec grid.
- No previous thermostat incentive. You must not have already received a smart thermostat rebate, discount or device from Enbridge Gas, Save on Energy or Home Renovation Savings.
- Home type. Single or semi-detached house, row or townhome, or mobile home on a permanent foundation. The terms exclude people living in multi-unit residential buildings and condominiums.
The terms add practical conditions: the thermostat must control your primary heating or cooling source; a gas fireplace does not count as gas heating unless the home is cooled electrically and on the provincial grid; hybrid gas and electric systems are accepted; and you need a home Wi-Fi connection so the manufacturer can confirm the installation.
Homes heated with propane, oil or wood are not named in the heating condition, but they can qualify through the electricity route if they cool electrically (for example, central air conditioning) and are on the Ontario grid. If your situation is unusual, confirm with the program before buying.
Which thermostats qualify
Only models on the program’s own eligible list qualify, and the list can change. On November 13, 2026, the official smart thermostat page listed models from six brands. The page links to compatibility tools so you can check your wiring before buying.
- Buy a new unit: used, refurbished and open-box thermostats are not eligible.
- A thermostat included free with a furnace, air conditioner or heat pump package is not eligible for the rebate.
- Check compatibility first: a low-voltage (24 V) furnace thermostat is not designed for electric baseboards, and baseboard models are not designed for a forced-air furnace.
- The rebate covers one thermostat. If you have several baseboard zones, only one unit is rebated.
Instant code or after you buy: how to claim
Both routes pay the same advertised amount, but you can use only one of them, and they work very differently.
| Before you buy (instant) | After you buy (post-purchase) | |
|---|---|---|
| Step 1 | Request a code with the “Get code” button on the program page | Buy an eligible model from any retailer, online, in store or through a contractor |
| Step 2 | Use the emailed code at checkout with a participating retailer listed on the program page | Upload your receipt within 60 days of purchase |
| When you get the money | At checkout | Email decision within about two weeks, payment up to 60 days after approval |
| How it is paid | Discount on your purchase | Enbridge customers: bill credit; electricity, propane, oil or wood customers: cheque or another IESO method |
| Receipt requirements | None beyond the purchase | Purchase date, model, pre-tax cost and retailer shown as separate details; pre-tax cost at least equal to the rebate |
| Best for | Buying now from a listed retailer | Buying elsewhere, through an installer, or a unit already bought since January 28, 2025 |
Two details catch people out. First, the instant code works only with the specific retailers and channels listed on the program page and in the FAQ (one retailer accepts it in store but not on its website). Second, new or recently moved Enbridge customers are asked to wait two to three weeks before applying so their account appears in the system.
RénoClair tip
Before you request an instant code, open the retailer’s checkout page and confirm it has a promo code field for this program. If not, buy where you like and use the after-you-buy route: the amount is the same, you just wait longer for it.
Deadline: December 31, 2026
Both sets of terms say you must “purchase, install and activate” an eligible thermostat between January 28, 2025 and December 31, 2026, and that “this offer ends on December 31, 2026”. The program web pages we read on November 13, 2026 show no earlier end date.
- A retailer may set an earlier end date for its own promotion. Check the offer and code expiry before relying on a particular retailer.
- For the after-you-buy route, apply within 60 days of purchase and submit by December 31, 2026 to stay within the published offer period. If you expect to apply later, confirm the deadline with the program before buying.
- Rebates are not guaranteed to be renewed in 2027. If you want one, buying and installing in November or December 2026 is the safe choice.
Worked example: what you actually pay
Here is a dated example for an Ontario homeowner who buys a hypothetical smart thermostat with a pre-tax price of $249.99 and uses the after-you-buy route. Ontario’s HST rate is 13% according to the Canada Revenue Agency GST/HST rate table. Prices vary widely by model; use your own quote.
| Line | Amount |
|---|---|
| Thermostat, pre-tax | $249.99 |
| HST (13%) | $32.50 |
| Paid at the register | $282.49 |
| Less rebate at $125 (website amount) | $157.49 net cost |
| Or less rebate at $100 (Jan. 2026 terms base amount) | $182.49 net cost |
| Less Peak Perks enrolment payment ($75), if eligible | $82.49 net after year 1 |
| Less two annual Peak Perks payments ($20 x 2) | $42.49 net after year 3 |
In this example, the gap between the website amount and the base amount in the terms is $25.00, which is why it is worth keeping a screenshot. Adding Peak Perks (only if you have central air conditioning controlled by the thermostat) brings the net cost down to $82.49 after the first year and $42.49 after three years of participation. The rebate is paid after tax here because you pay the full price at the register and receive a bill credit or cheque later; how a retailer applies an instant code against HST is up to the checkout system, so check your receipt.
If the thermostat is part of a new heating or cooling system, redo the full project calculation with your own sizes in our heat pump cost calculator (currently based on Québec prices, so treat the result as a starting point for Ontario), and check the separate equipment rebate with our heat pump rebate calculator.
Stacking with Peak Perks and other programs
The thermostat rebate itself cannot be doubled, but it pairs with Peak Perks. The program FAQ says the rebate and Save on Energy’s Peak Perks program “are designed to complement each other”.
- No double rebate on the thermostat: the instant rebate and the post-purchase rebate cannot be combined, and the same thermostat cannot receive another rebate from the program administrators.
- Peak Perks (summer demand response): according to the Save on Energy Peak Perks page, you receive $75 when you enrol and $20 for each year you stay enrolled, by virtual prepaid card or e-Transfer. You must be an Ontario residential electricity customer with central air conditioning (or a heat pump that is part of central air) controlled by an eligible Wi-Fi smart thermostat.
- How events work: from June to September, on hot weekday afternoons, your thermostat can be raised by no more than 2°C for up to three hours. You are notified beforehand and can opt out of any event from the thermostat or its app.
- Renters and condos: Peak Perks accepts renters who meet the other conditions, and low-rise units with their own air conditioning, even though the thermostat rebate excludes condos.
- Bigger upgrades are separate: heat pumps, insulation and other measures have their own rules in the Home Renovation Savings program. Gas customers can also read our Enbridge heat pump rebate guide.
Common mistakes and a checklist before you buy
- Buying a model that is not on the program’s current list (or a used or open-box unit).
- Living in a condo or a multi-unit building: the thermostat rebate does not apply, even if you own the unit.
- Missing the 60-day receipt window on the after-you-buy route.
- Uploading a receipt where the thermostat is bundled with installation and has no separate pre-tax price.
- Claiming a second time at the same address after a previous Enbridge, Save on Energy or program thermostat incentive.
- Installing a 24 V model on electric baseboards (or the reverse) and having to return it.
- Waiting until late December: the thermostat must be installed and activated, with Wi-Fi connected, by December 31, 2026.
Installing it yourself? Turn the power off at the breaker before touching the wiring, especially for line-voltage baseboard thermostats. Our winter home maintenance checklist covers the other heating tasks to do before the cold sets in.
Frequently asked questions
Is there a smart thermostat rebate in Ontario in 2026?
Yes. The Home Renovation Savings program offers a smart thermostat rebate for eligible thermostats bought, installed and activated between January 28, 2025 and December 31, 2026, with one rebate per household.
How much is the smart thermostat rebate Ontario homeowners get?
$125 according to the program website on November 13, 2026. The January 2026 terms still state $100, or $125 for Energy Affordability Program kit recipients, so keep a screenshot of the amount you were offered.
Can I get the rebate if I live in a condo?
No. The terms exclude condominiums and multi-unit residential buildings. Eligible homes are single or semi-detached houses, row or townhomes, and mobile homes on a permanent foundation.
I already bought a smart thermostat. Can I still claim it?
Yes, if you bought an eligible new model on or after January 28, 2025, you upload the receipt within 60 days of purchase, and you have never received a thermostat incentive from Enbridge Gas, Save on Energy or the program.
Do I need central air conditioning?
Not for the rebate: the thermostat must control your primary heating or cooling. Central air conditioning (or a central heat pump) controlled by the thermostat is required only for Peak Perks.
Can I combine the rebate with Peak Perks?
Yes. The program says the two are designed to complement each other: Peak Perks pays $75 at enrolment and $20 per year if you have eligible central cooling.
How much does a smart thermostat cost after the rebate?
In our example, a $249.99 thermostat costs $282.49 with 13% HST and $157.49 after a $125 rebate. For a full heating project, estimate the price with our heat pump cost calculator (currently based on Québec prices).
How long does it take to get paid?
For the after-you-buy route, expect an email decision within about two weeks and payment up to 60 days after approval. The instant route discounts the price at checkout.
The bottom line
Ontario’s Home Renovation Savings program advertises a $125 smart thermostat rebate for eligible households. Confirm your amount before buying, check that your home and heating or cooling system qualify, and complete the installation and activation by December 31, 2026. Choose the instant code if a listed retailer suits you, otherwise claim with your receipt within 60 days, and add Peak Perks if you have central air. If the thermostat is part of a larger heating project, run the numbers in our heat pump cost calculator first.
