Ontario Attic Insulation Rebate For Kanata Homes

Path One: The Attic Insulation Rebate Without An Assessment

No energy audit is needed on this route. The attic insulation rebate amount is tied to what the attic holds before work starts:

Starting at R-12 or below and finishing at R-50 or more pays as much as $1,250.

Starting above R-12 and no higher than R-25 pays as much as $1,000.

Starting above R-25 and no higher than R-35 pays as much as $800.

Cathedral ceilings and flat roofs have their own attic insulation rebate tiers: $750 for taking R-25 or less up to R-28, or $650 for taking R-12 or less up to R-20. Whichever tier applies, the attic insulation rebate stops at half the after-tax cost of the job, and the whole reachable attic has to be done, not just the coldest corner.

The catch is the installer. Only firms on the program's own list can claim this route, and the program has stopped adding names to that list. In October 2026 that closed list named six companies: Brand Insulation, EcoComfort, George Kent, Great Northern Insulation, Home Depot and Solidcare. Look the list up on homerenovationsavings.ca before you book anyone on the strength of this route.

Path Two: The Attic Insulation Rebate With An Assessment

The second path starts with a home energy assessment by a registered energy advisor. You choose at least two upgrades from the report, have your preferred contractor do the work, and then book a follow-up assessment with the same advisor. On this route the attic insulation rebate is larger: up to $1,500 from R-12 or less, $1,200 from R-12 to R-25 and $900 from R-25 to R-35, with $780 for a cathedral ceiling or flat roof. Any contractor can do the work on this path, which is the route to read about if the company you want is not on the list above.

The program also gives $600 toward the two assessments, and a third upgrade earns another $500. It suggests air sealing as a third upgrade, which pairs well with our attic air sealing work.

Who Qualifies For The Attic Insulation Rebate

Owners of detached houses qualify for the attic insulation rebate, along with semis, row houses, non-stacked townhouses and mobile homes fixed to a permanent foundation. A gas-heated house needs an active Enbridge Gas account and a gas furnace or boiler; a house heated by hydro, oil, propane or wood needs to be on Ontario's power grid. Houses occupied for six months or less, stacked townhouses and any address that was paid an attic rebate before, by Enbridge, Save on Energy or another Ontario program, are left out. A landlord can apply for the attic insulation rebate on a rental, and a seasonal cottage may qualify.

What We Provide For Your Attic Insulation Rebate

Any rebate form wants to know what the attic had and what it has now. Our photo check records the starting R-value with dated pictures, and the invoice records the finished R-value and the area covered. On the audit route, the advisor's report names the target, and a blown-in cellulose insulation quote can be written to match it.
