What Is the Attic Insulation Rebate in Ontario?
How the 2026 HRS rebate helps pay for your attic upgrade
The attic insulation rebate Ontario homeowners claim in 2026 comes from the Home Renovation Savings (HRS) program, delivered through Enbridge Gas. It pays you to top up an under-insulated attic to the R-60 standard. Most GTA homes built before 1990 have just 5–8 inches of insulation, compared with the recommended 16+ inches.
About 25% of your heat escapes through the roof, according to the U.S. EPA estimate. Topping up to R-60 helps keep upstairs rooms warmer in winter and cooler in summer. For many attic projects, the rebate covers up to 100% of the insulation cost. The program runs through November 30, 2026. A free CES assessment confirms your eligibility before you spend anything.
What Happens During the Free Rebate Assessment?
We start with a free visit that takes about 30–45 minutes. Our inspector checks the attic and explains the work, cost and rebate:
- Measures your current insulation depth at several points, since the depth can vary across the attic
- Calculates the depth needed to reach R-60 for your home's dimensions and our climate zone
- Checks ventilation, air sealing, and any mould or moisture issues that should be fixed before insulating
- Confirms your rebate eligibility by checking your utility account, property type and which stream pays you more
- Gives you a firm, all-in quote the same day showing the project cost minus your expected rebate, in writing
The quote is yours to keep, with no obligation to book. If you go ahead, installation is usually within 1–2 weeks. We handle all the rebate paperwork.
Which Insulation Types Qualify for the Rebate?
The rebate is for reaching R-60, so you can choose the material that suits your attic. The usual options are:
- Blown-in fiberglass or cellulose is the most common choice for rebate projects. It goes over existing insulation, fills around joists and wires, and is the most cost-effective way to reach R-60.
- Batt (roll) insulation comes in pre-cut fiberglass or mineral wool panels. It works best with open, standard framing and no obstructions.
- Spray foam is the premium option. It has the highest R-value per inch and also forms an air barrier. It is usually chosen for attic conversions or unusual roof shapes.
Most GTA homes already have some blown-in insulation. During the free assessment, we measure what is there and recommend the quickest way to reach R-60 and get the largest rebate.
Do You Qualify for the Attic Insulation Rebate?
Most GTA families are eligible. Start with these six requirements.
Detached, semi-detached, row townhome, or mobile home on a permanent foundation
The upgrade must be to the home you live in. Rental properties and cottages do not qualify.
Enbridge Gas customer, OR electricity / propane / oil heating for the multi-measure stream
Already claimed an attic rebate? You can still claim for basement or walls
Your attic must reach the program's R-60 insulation level. We check this during the free assessment.
The program has been extended but may close when funding runs out. Early applicants get priority.
If you checked most of these boxes, your home almost certainly qualifies for the attic insulation rebate. Our free assessment confirms this in one visit. We measure the insulation already in place, check your eligibility and calculate your rebate.

Two Attic Insulation Rebate Examples
A worked example using 2026 program amounts and CES standard rates
These examples are illustrative. Your free assessment gives the figures for your home.
| Semi-detached home, 1,800 sq ft → attic area (×0.6) | ≈ 1,100 sq ft |
| Existing insulation: 4–5 inches → top-up to R-60 | $1.15–$1.30 / sq ft |
| Estimated project cost (1,100 sq ft) | $1,265–$1,430 |
| Standalone attic rebate (no assessment stream) | up to −$1,250 |
| Net cost, as low as | $15–$180 |
…plus $400–$1,200 per year in lower heating and cooling costs, every year after.
Second example: an unfinished attic with no insulation
| Detached home, 2,400 sq ft → attic area (×0.6) | ≈ 1,440 sq ft |
| No existing insulation → insulate to R-60 | $1.45 / sq ft |
| Estimated project cost (1,440 sq ft) | ≈ $2,088 |
| Standalone attic rebate | up to −$1,250 |
| Approximate net cost | ≈ $838 |
Homes with no attic insulation see the biggest comfort change and the largest reduction in hydro and gas bills. If your attic is bare, ask about combining the work with basement insulation through the multi-measure stream for a larger rebate.
Is the Attic Insulation Rebate Different Across GTA Cities?
The same Ontario rebate amounts apply across Toronto, Mississauga, Brampton and other communities. Your home's insulation is what makes the difference. Etobicoke's 1950s bungalows, Hamilton's century homes and Mississauga's 1970s subdivisions often have more to top up. That can mean a larger rebate for an upgrade to R-60.

Scheduling varies by location. CES crews cover the western GTA, including Mississauga, Oakville, Hamilton and Burlington; Vaughan, Brampton and the Richmond Hill area; and Toronto, including North York, Scarborough and Etobicoke.

Insulation Rebate FAQ
Yes. The Ontario Home Renovation Savings program has been extended through November 30, 2026. It can close earlier if funding runs out, so applying early gives you more time to complete the process.
Not for the standalone attic stream (up to $1,250). The multi-measure stream (up to $10,000) requires both a pre-work and post-work energy assessment by a Registered Energy Advisor.
Typically 6–8 weeks after a complete application is submitted. Enbridge Gas customers receive a credit on their gas bill; other customers receive a cheque. Processing times depend on application volume. Early applications generally move faster, so allow time before the November 30, 2026 deadline.
Yes. The multi-measure stream lets you combine attic insulation with basement or wall insulation, air sealing, windows, doors, smart thermostats and other eligible upgrades. Rebates total up to $5,000 for natural gas homes or $10,000 for homes heated by electricity, propane or oil. You need an energy assessment before and after the work, and we arrange both. For many homeowners, the combined rebate covers most or all of the attic work.
You cannot claim a second rebate for the same area. However, you can still receive rebates for other areas such as basement insulation, wall insulation, or exposed floor insulation.
Yes. We explain the requirements and help you prepare the documents and follow the application through. A qualified independent auditor assesses the home and determines final eligibility.
The Home Renovation Savings program funds the rebate. Enbridge Gas delivers it for natural gas homes, with payment as a bill credit or cheque after approval, rather than from your insulation contractor. Homes heated by electricity, propane or oil qualify for the same amounts through the multi-measure stream.
You must own a detached or semi-detached home, a row townhome or a mobile home on a permanent foundation, and be upgrading your primary residence. You also need an active Enbridge Gas account, or an active electricity, propane or oil account for the multi-measure stream, and must upgrade the attic to R-60. Cottages and rental properties do not qualify. A free CES assessment confirms eligibility in about 10 minutes.
Yes. You pay the contractor for the completed work, then submit the rebate application. CES prepares the paperwork. Most homeowners receive payment within 6–8 weeks of approval. On smaller projects, the rebate can cover up to 100% of attic insulation costs, leaving many CES customers with very little to pay after the rebate arrives.
No. The program covers primary residences, not rental units, cottages or second homes. Most homes that owners live in qualify. A free assessment confirms whether yours does.
Most GTA attic top-ups cost $1,200 to $2,800, depending on the attic size and insulation already in place. Rates are roughly $0.99–$1.45 per sq ft, with the attic area estimated at about 60% of the home's floor area. For attic-only projects, the rebate reduces that cost by up to $1,250. Many homeowners pay close to nothing once it arrives.
No. GreenON has closed, and Union Gas merged with Enbridge Gas. The Home Renovation Savings (HRS) program, delivered through Enbridge Gas, is the current Ontario program for 2026. Older GreenON and Union Gas pages do not show the current offers. The HRS amounts on this page apply through November 30, 2026.
