Is your attic insulation thin, se
ttled, or original to a home built more than 15–20 years ago? Right now is the best financial window in years to fix it. The Home Renovation Savings program is the current Enbridge-backed rebate for Ontario homeowners. It offers a standalone rebate of up to $1,250 toward attic insulation upgrades. You don’t need to bundle the work with other renovations to qualify.
Enbridge has reportedly extended the program through November 30, 2026. That date matters more than it sounds. Rebate programs like this one have closed early before, when funding ran out. This specific program even replaced an older Enbridge rebate that stopped taking applications at the end of 2025. If you’ve put off an attic upgrade, act this fall — the rebate is confirmed active right now, and the coldest weeks of the year haven’t yet created a scheduling backlog.
What Is the Attic Insulation Rebate, Exactly?
The rebate runs through the Home Renovation Savings program — the current Enbridge-backed insulation rebate for Ontario homeowners. It’s worth being precise here, because homeowners (and sometimes contractors) mix up rebate program names constantly.
Enbridge previously ran a different program called the Home Efficiency Rebate Plus. That program required a full home energy assessment, and it stopped accepting new applications at the end of 2025. Home Renovation Savings is the current, separate program. It includes a standalone attic insulation stream, which means you don’t need to also redo your furnace, windows, or walls to qualify. Attic insulation alone is enough.
How Much Can You Get?
The Home Renovation Savings program calculates the standalone attic insulation rebate at 50% of your total insulation cost after tax, up to a maximum. That maximum depends on your attic’s current insulation level:
- Up to $1,250 for attics with R-12 insulation or below (the thinnest, most under-insulated attics)
- Up to $1,000 for attics currently between R-12 and R-25
- Up to $800 for attics currently between R-25 and R-35
To qualify, your finished upgrade generally needs to reach R-50 or higher. Your exact rebate tier depends on your home’s current insulation level. We measure that level during an in-home inspection — we don’t guess it. Book a free inspection, and we’ll confirm exactly which tier your home qualifies for as part of your quote.
The Home Renovation Savings program — not any individual contractor — sets these rebate amounts and tier thresholds, and it can change them at any time. We confirm current figures as part of every quote instead of relying on a number that might already be outdated.
Why the November 30, 2026 Deadline Matters
Two things make this deadline worth acting on now, instead of waiting.
Rebate Programs Have Closed Early Before
The program that came before this one stopped accepting applications once its funding ran out. That happened ahead of most homeowners’ expectations. Enbridge’s current stated timeline extends the rebate to November 30, 2026 — but that’s not a guarantee the funding lasts that long.
Demand Spikes the Moment the Weather Turns
Attic insulation demand spikes hard once the weather turns. September through November is historically the busiest stretch for attic upgrades in the GTA. Homeowners feel the first cold mornings, remember last winter’s heating bill, and call all at once. The closer you get to December, the longer you’ll wait between your call and an actual install date. Combine a hard rebate cutoff with a seasonal scheduling crunch, and “I’ll get to it in November” quietly turns into missing the deadline altogether.
Book your inspection in September or October, rather than waiting for the first cold snap. That gives you the best odds of completing the work, passing inspection, and filing the rebate application before anything closes.
Do You Qualify?
Eligibility for the Home Renovation Savings attic insulation rebate generally requires:
- A home heated by natural gas, electricity, oil, propane, or wood
- A detached, semi-detached, townhouse, or condominium unit
- Existing attic insulation below the program’s R-value thresholds
- A contractor who meets the program’s participation requirements to complete the work
This isn’t a program you self-certify for after the fact. We confirm eligibility against your home’s actual, measured insulation level. A free in-home inspection establishes that measurement before any work starts, and before we file any rebate paperwork.
What Attic Insulation Upgrade Actually Qualifies?
Most rebate-eligible attic upgrades top up or replace insulation with blown-in cellulose or fiberglass insulation — the most common approach for attics with thin, settled, or uneven original coverage. Spray foam insulation suits homes with drafts or complex rooflines better, since it combines insulation and air sealing in one step. Straightforward, regularly shaped attics can sometimes use fiberglass batt insulation instead.
We help you pick the option that fits your home — and reaches the R-value the rebate requires — after an inspection, not before one. For the full picture on attic insulation types, R-values, and what drives cost, see our complete attic insulation guide for Ontario homeowners.
How to Claim the Rebate: Step by Step
- Book a free in-home inspection. We measure your attic’s current insulation level. That measurement determines your rebate tier.
- Get a written, itemized quote. We lay out material, scope, and price, and confirm your estimated rebate amount against current program rules.
- Installation. We upgrade your attic to the coverage level the rebate program requires.
- Rebate application filed. We file the paperwork and match the documentation to what the program requires, so a technicality doesn’t delay or reject your claim.
The rebate ties to a specific post-upgrade R-value. That’s why working with a contractor who understands the program’s documentation requirements matters. A job that “looks done” but skips proper measurement and filing can cost you the rebate, even when the insulation itself is fine.

Frequently Asked Questions
How much is the attic insulation rebate in Ontario right now? Up to $1,250 through the Home Renovation Savings program. The program calculates it at 50% of your insulation cost after tax. The exact amount depends on your attic’s current insulation level — homes starting from the thinnest coverage (R-12 or below) qualify for the highest tier.
When does the attic insulation rebate end? Enbridge has reportedly extended the program through November 30, 2026. The program can still close earlier if funding runs out before that date. We recommend starting the process well before late fall.
Do I need to do other renovations to qualify, or can I just do my attic? Attic insulation is a standalone rebate stream. You don’t need to bundle it with furnace, window, or wall upgrades to qualify.
How do I know what insulation tier my home qualifies for? We measure your current attic R-value during a free in-home inspection — we don’t estimate it over the phone. That measurement determines your rebate tier.
Is the Enbridge Home Efficiency Rebate the same as this program? No. That was a separate, earlier Enbridge program that required a full home energy assessment, and it stopped accepting new applications at the end of 2025. Home Renovation Savings — including the standalone attic stream — is the current active program.
How long does it take to get an attic insulation upgrade done before the deadline? It depends on scheduling demand, which increases significantly from September through November. Booking your inspection early in that window gives you the most buffer before any program cutoff.
What if I miss the November 30, 2026 deadline? Enbridge has historically replaced or renewed rebate programs like this one with new terms, rather than letting them disappear outright. But nothing guarantees that, or what a future program would offer. The safest approach: complete the work now, while the current rebate and its terms still stand.
