Attic Insulation Rebate In The Ottawa Valley, Ontario

What The Attic Insulation Rebate Pays

The standalone attic stream needs no energy assessment. It pays $1,250 when the attic starts at R-12 or less and finishes at R-50, $1,000 when it starts between R-13 and R-25, and $800 when it starts between R-26 and R-35. A flat roof or cathedral ceiling gets $750 for going from R-25 or less to R-28, or $650 for going from R-12 or less to R-20.

Two limits sit on every attic insulation rebate. The amount cannot pass half of what the job costs after tax, and the entire reachable attic must be done, not only the easy part near the hatch.

The Assessment Route Attic Insulation Rebate

The second route brings in a registered energy advisor to inspect the house before and after, and it expects at least two upgrades. Its attic insulation rebate rises to $1,500, $1,200 or $900 for those same starting depths, and to $780 for a flat roof or cathedral ceiling.

On this route the choice of contractor is yours. The advisor's two reports, with an invoice showing the depth before and after, are what back the claim.

Who Can Claim The Attic Insulation Rebate

You must own the home, and it must be a detached, semi-detached or row house, a non-stacked townhouse, or a mobile home sitting on a permanent foundation. A house on Enbridge natural gas needs an active account and a gas furnace or boiler. A house heated with electricity, propane, oil or wood needs to be connected to Ontario's electricity grid.

Stacked townhouses are out, as are homes occupied for half the year or less and any address that already collected an attic insulation rebate through Enbridge, through Save on Energy or through another Ontario program. Landlords can apply for a rental, while a seasonal cottage may still qualify.

Check The Attic Insulation Rebate Contractor List First

The standalone stream pays only when a contractor on the program's list of names does the work and files the paperwork, and the program has stopped adding to that list. At our last check it named George Kent, Solidcare, Great Northern Insulation, Home Depot, Brand Insulation and EcoComfort. Look the list up on the program's website ahead of booking anyone for an attic insulation rebate job. If you would rather choose your own installer, the assessment route keeps that choice open.

How Long The Attic Insulation Rebate Lasts

The program is currently scheduled to end November 30, 2026. It was extended once already, from the same date in 2025, and could be extended again, but the money goes out first come, first served, and the official page prints no closing date. Treat November as the working deadline for an attic insulation rebate.

Whatever happens to the rebate, sealing and filling the attic to R-60 still cuts the heat lost through the ceiling every winter. Our attic insulation cost page shows what the work itself usually runs.
