Quick answer: Ontario’s main insulation rebate in 2026 is the Home Renovation Savings Program, run by Enbridge Gas and Save on Energy. It has two paths: a standalone attic rebate of up to $1,250 with no energy assessment, and a bundle path that pays up to $7,700 for insulation when you do an energy assessment and two or more upgrades. The federal Canada Greener Homes Grant is closed. The program is currently scheduled to run until March 31, 2027, and amounts can change.

Key takeaways
- If you only want to upgrade your attic, the standalone attic path is the fastest: no audit, up to $1,250.
- If you are also doing walls, basement, windows or a heat pump, the bundle path can pay much more.
- You cannot claim the attic rebate on both paths.
- Rebates are first-come, first-served and can end early. Book before you buy.

How to choose your rebate path
Answer three questions:
- Is the attic the only thing you are upgrading in the next year? If yes, use the standalone attic path.
- Are you planning two or more upgrades (attic plus walls, basement, air sealing, windows, heat pump)? If yes, the bundle path usually pays more.
- Can you wait for two energy assessments? The bundle path needs one before work starts and one after. If you need the work done soon, the attic path is simpler.
Rebate math: what you actually get back
Both attic rebates pay a fixed amount per measure, with the attic path capped at 50% of the after-tax cost. Here is what the standalone attic rebate covers at different job prices:
| After-tax job cost | R-12 or less (max $1,250) | R-12 to R-25 (max $1,000) | R-25 to R-35 (max $800) |
|---|---|---|---|
| $1,500 | $750 | $750 | $750 |
| $2,000 | $1,000 | $1,000 | $800 |
| $2,500 | $1,250 | $1,000 | $800 |
| $3,000 | $1,250 | $1,000 | $800 |
| $4,000 | $1,250 | $1,000 | $800 |

Frequently asked questions
What is the best insulation rebate in Ontario right now?
For an attic-only job, the standalone attic path of the Home Renovation Savings Program is the simplest at up to $1,250. For bigger projects, the bundle path pays more in total, up to $7,700 for insulation plus $600 toward the assessment.
Is the Canada Greener Homes Grant still available?
No. It closed to new applications in February 2024 and the final document deadline was December 31, 2025. See what replaced it.
Can I combine the attic rebate with the bundle path?
You can use the bundle path for other upgrades, but you cannot claim an attic rebate on both paths. Pick the attic path that pays you more for your situation.
Are rebates taxable?
Rebates reduce the cost of your upgrade. If you have questions about your own tax situation, ask your accountant.
How long does the rebate take?
For the attic path, cheques typically arrive within a few months of the application being approved. The bundle path takes longer because of the second energy assessment.
