Attic Insulation Rebates in Ontario: What's Actually Still Available in 2026

No. The federal Canada Greener Homes Grant closed to new applicants in February 2024, and December 31, 2025 was the final deadline for participants to submit documents. It is now closed.

If you submitted everything by the applicable deadline, NRCan may still be processing your existing file. New applicants need to look at other federal, provincial, utility, or municipal programs instead.

The federal government's successor program is the Canada Greener Homes Affordability Program (CGHAP), backed by roughly $800 million over five years. Unlike the original grant, CGHAP is targeted at low-to-median income households and renters, and it provides no-cost retrofits — including insulation — rather than a reimbursement homeowners apply for themselves.

CGHAP is rolling out province by province. Manitoba was first to launch in 2025, with British Columbia, Quebec, Nova Scotia, and Prince Edward Island added through 2026. As of this writing, Ontario does not yet have a signed delivery agreement or application portal, though it's expected to eventually participate. If you're in the GTA, this program isn't accessible yet — but it's worth checking NRCan's Greener Homes page periodically, or asking your contractor if there's been an update.

For eligible Ontario homeowners today, a currently active attic-insulation rebate runs through the Home Renovation Savings (HRS) program, delivered by Enbridge Gas and Save on Energy. Eligibility depends on factors including the home's heating fuel and the program stream, so homeowners should confirm the current requirements before starting work.

There are two paths. The standalone attic insulation rebate requires no home energy assessment — as of January 2026, it offers up to $1,250 for a standard attic insulation upgrade, or up to $750 for cathedral ceiling or flat roof insulation. This is the simpler route for a straightforward top-up or re-insulation project.

The multi-measure path requires a pre- and post-retrofit home energy assessment but unlocks a higher rebate ceiling — up to $7,700 specifically for insulation as part of a broader retrofit, within an overall program cap of $5,000 for natural gas heated homes or $10,000 for electrically heated homes. This path makes the most sense if you're planning insulation alongside other upgrades like air sealing, a heat pump, or new windows.

First, confirm you're an Enbridge Gas customer — the program is tied to your gas account, not your home's location alone. Next, decide which path fits your project: the standalone attic rebate if insulation is your only upgrade, or the multi-measure path if you're bundling insulation with other retrofits and want access to the higher rebate amounts.

Your installed insulation needs to meet minimum R-value thresholds to qualify, so it's worth confirming this with your contractor before work begins rather than after. Keep your contractor invoice and any required documentation — you'll need it to submit your rebate claim.

Because eligibility rules and rebate amounts are updated periodically, always confirm the current figures directly on Enbridge Gas's Home Renovation Savings page, or ask your contractor to walk you through what applies to your specific project before you commit.

Beyond Enbridge's program, some municipalities offer financing options rather than outright grants — Toronto's Home Energy Loan Program (HELP), for example, lets homeowners finance energy retrofits and repay through their property tax bill, which can make a larger project more manageable even without reducing the sticker price.

Rebate programs in this space change often, so it's worth asking your contractor directly what's currently available when you get a quote — a contractor who does this work regularly will usually know about new or updated programs before they're widely publicized.

Rebate paperwork shouldn't be the reason you put off a project that pays for itself in comfort and energy savings. When you book with us, we help you understand which current rebate path fits your situation, make sure the insulation we install meets the R-value thresholds required to qualify, and provide the documentation you need to submit a claim.

If you're not sure whether your attic qualifies for a rebate, or which path makes more sense for your project, get in touch — we're happy to walk through it before you commit to anything.
