If you own a home in Toronto — especially one built before modern insulation standards existed — your attic is likely losing more heat than it should. The good news: an attic insulation rebate is currently available to Toronto homeowners through Ontario’s Home Renovation Savings program, and it can offset a meaningful chunk of the cost of fixing it.
Here’s what the attic insulation rebate covers, how much Toronto homeowners can actually get, and what qualifies.
Why Toronto Attics Are a Prime Candidate for This Rebate
A large share of Toronto’s housing stock — particularly in the city’s older, established neighbourhoods — predates modern attic insulation requirements by decades. That means the insulation up there hasn’t been touched since the home was built, or has settled and thinned out over time. The result shows up as top-floor rooms that never quite match the thermostat, heating bills that climb every winter, and in some homes, ice damming along the roofline where escaping heat melts snow unevenly.
The Home Renovation Savings rebate exists specifically to make fixing this more affordable, and Toronto’s older housing stock is exactly the kind of home the program is built for. For the full picture on what qualifies as a Toronto attic insulation upgrade, see our Toronto Attic Insulation Rebate Page.
How Much Is the Attic Insulation Rebate?
The Home Renovation Savings program calculates the standalone attic insulation rebate at 50% of your insulation cost after tax, up to a maximum that depends on your attic’s current insulation level:
- Up to $1,250 for attics currently at R-12 insulation or below (the thinnest, most under-insulated attics — common in older Toronto homes)
- 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, the finished upgrade generally needs to reach R-50 or higher. Your exact tier depends on your home’s current insulation level, which we measure during an in-home inspection rather than estimating over the phone.
You don’t need to bundle attic work with other renovations to qualify — attic insulation has its own standalone rebate stream under this program.
Do Toronto Homeowners 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
- Work completed by a contractor who meets the program’s participation requirements
Toronto’s mix of century homes in neighbourhoods like Riverdale and Cabbagetown alongside newer builds across the city means eligibility varies house to house — a fast way to check where you stand is the rebate eligibility quiz, which walks through your home’s basic details before you book an inspection.
What Kind of Attic Insulation Qualifies
Most rebate-eligible upgrades in Toronto homes use blown-in cellulose or fiberglass insulation — the standard fix for attics with thin, settled, or uneven original coverage, which describes a lot of Toronto’s older housing stock. Spray foam insulation is a better fit for homes with drafts or complex rooflines, since it handles insulation and air sealing in the same step. Straightforward, regularly shaped attics can sometimes use fiberglass batt insulation instead.
The right option depends on your specific attic, which is why we confirm it during an inspection rather than guessing beforehand.
How to Claim the Rebate in Toronto
- Book a free in-home inspection. We measure your attic’s current insulation level, which determines your rebate tier.
- Get a written, itemized quote. Material, scope, price, and your estimated rebate amount, based on current program rules.
- Installation. Your attic is upgraded to the coverage level the rebate program requires.
- Rebate application filed. We handle the paperwork and match documentation to program requirements.
A job that looks finished but skips proper measurement and filing can cost you the rebate even when the insulation itself is fine — which is why the contractor doing the work matters as much as the insulation itself. Our guide on how to hire the right insulation contractor covers what to check before signing anything.

It applies to any qualifying Toronto home, but older homes with thin or original insulation are the most common candidates and typically qualify for the highest rebate tier.
