If your Ottawa home has an under-insulated attic, there is a genuine opportunity on the table right now that many homeowners in Stittsville and across Ottawa west do not know about. The Ontario Home Renovation Savings Program is offering a rebate of up to $1,250 for attic insulation upgrades, with no home energy assessment required, and it is scheduled to run only through November 30, 2026.
Attic insulation is one of the most cost-effective improvements you can make to an Ottawa home. It reduces heating costs through our long winters, helps prevent the ice dams that Ottawa’s freeze-thaw climate produces, and improves year-round comfort. With this rebate covering up to half the cost, the case for upgrading before the deadline is strong.
This post explains how the rebate works, who qualifies, how much you can actually get back, and how to claim it before the program ends.
Key Takeaways
- The Ontario Home Renovation Savings Program offers a standalone attic insulation rebate of up to $1,250, with no home energy assessment required, through November 30, 2026.
- The rebate pays 50% of your total insulation cost after tax, up to the maximum for your tier. It is not a flat payment.
- The exact amount depends on your existing insulation level: up to $1,250 if your attic is at R-12 or below, $1,000 for R-12 to R-25, and $800 for R-25 to R-35. You must upgrade to R-50 or higher and insulate 100% of the accessible attic.
- To qualify, you must own the home, heat it with Enbridge natural gas or be connected to an eligible Ontario electric utility, and not have previously received this rebate at your address.
- The program can end early if funding runs out, so Ottawa homeowners considering an upgrade should act well before the November 30 deadline.Disclaimer: Rebate programs are subject to change and while we do our best to ensure information is up to date and accurate always consult the current conditions for rebates you may hope to claim before making any financial decisions.

What Is the Ontario Attic Insulation Rebate?
The rebate is part of the Home Renovation Savings Program, a government-backed energy efficiency program delivered jointly by Enbridge Gas and Save on Energy (the Independent Electricity System Operator). It replaced the earlier Home Efficiency Rebate Plus program and covers a range of upgrades including insulation, windows, air sealing, and heat pumps.
What makes the attic insulation portion particularly attractive is that it includes a standalone path that does not require a home energy assessment. Under many rebate programs, you have to pay for an energy audit (often around $600) before and after the work. The standalone attic path skips that step entirely. Your existing insulation level is confirmed during the contractor’s in-home estimate, which quality contractors provide at no separate cost.
This makes the attic insulation rebate one of the simplest energy rebates currently available to Ottawa homeowners. There is no upfront audit cost and no bundling requirement with other upgrades.
How Much Money Can Ottawa Homeowners Actually Get Back?
The rebate covers 50% of your total insulation cost after tax, up to a maximum that depends on how much insulation your attic currently has. This tiered structure matters, so it is worth understanding clearly.
The less insulation you currently have, the more work is required to bring your attic up to standard, and the higher your rebate maximum. The tiers work as follows:
If your existing attic insulation is at R-12 or below, you may be eligible for up to $1,250.
If your existing insulation is between R-12 and R-25, you may be eligible for up to $1,000.
If your existing insulation is between R-25 and R-35, you may be eligible for up to $800.
In all cases, the program requires you to upgrade the attic to R-50 or higher and to insulate 100% of the accessible attic space.
Because the rebate is 50% of the cost up to your tier maximum, the actual amount you receive depends on both your starting point and the total cost of the job. As an example, a typical blown-in insulation upgrade might cost in the range of $2,500 to $3,000 before rebate. At 50% coverage up to the $1,250 maximum, a qualifying homeowner could see their real out-of-pocket cost cut roughly in half. Every home is different, so the specific numbers depend on your attic size, current insulation, and the scope of the work.
Who Qualifies for the Attic Insulation Rebate in Ottawa?
The eligibility requirements are specific, and it is worth confirming each one before planning an upgrade.
You must own the home. Renters are not eligible, though owners of rental properties may qualify for their properties. The home must be your primary residence or occupied for more than six months of the year, and new construction does not qualify.
Your home must be an eligible property type: a single-detached, semi-detached, row house, non-stacked townhome, or a mobile home on a permanent foundation. Stacked townhomes are not eligible.
Your home must meet the heating requirement. Either it is heated with natural gas supplied by Enbridge Gas through a furnace or boiler, or it is heated with electricity, oil, wood, or propane and connected to an eligible Ontario local electric utility. Most Ottawa-area utilities qualify.
Your existing attic insulation must be at R-35 or below, and you must plan to upgrade 100% of the accessible attic space to R-50 or higher.
Your home must not have previously received an attic insulation rebate from Enbridge Gas, Save on Energy, or another Ontario program. This applies to the address, not the owner. If a previous owner claimed the rebate on your home, it is not eligible again.
Why Does Attic Insulation Matter So Much in Ottawa?
Beyond the rebate, attic insulation delivers real, ongoing value in Ottawa’s climate, which is what makes this rebate worth acting on rather than letting it pass.
Ottawa winters are long and cold, and heat rises. A poorly insulated attic allows the heat you are paying for to escape through the roof, which drives up your heating costs every single month of the winter. Upgrading to R-50 or higher significantly reduces that heat loss.
Attic insulation also plays a direct role in preventing ice dams. Ice dams form when heat escaping into the attic warms the roof deck, melts the snow on the roof, and causes the meltwater to refreeze at the colder eaves. That ridge of ice forces water back under the shingles and into the structure. Proper attic insulation, combined with adequate ventilation, keeps the roof deck cold and uniform, which is what prevents ice dams from forming in the first place.
In summer, attic insulation works in the other direction, reducing the heat that radiates down into your living space from a hot attic and lowering your cooling costs.
This connection between insulation, ventilation, and your roof is why attic insulation is a natural companion to roofing work, and why it is worth considering as part of a broader look at your home’s performance.
Should You Upgrade Your Attic Insulation When You Replace Your Roof?
If you are already planning a roof replacement, upgrading your attic insulation at the same time is worth serious consideration.
The two systems are connected. Your roof, your attic insulation, and your attic ventilation all work together to manage heat and moisture. When a roof is being replaced, it is a natural point to assess whether the attic beneath it is performing as it should. Addressing insulation and ventilation deficiencies at the same time as the roof means the entire system starts fresh and works together, rather than installing a new roof over an attic that is still losing heat and generating ice dams.
The rebate makes this timing even more attractive. Combining a roof replacement with a rebate-eligible insulation upgrade lets you improve your home’s performance and recover part of the insulation cost in the same project window.
How Do You Apply for the Rebate?
The process is straightforward, particularly on the standalone attic path.
First, have a participating contractor assess your attic and provide a quote. The contractor confirms your existing R-value during the in-home estimate, which determines your rebate tier. There is no separate energy assessment to book or pay for on the standalone path.
Second, the insulation work is completed by the participating contractor, upgrading your attic to R-50 or higher across 100% of the accessible space.
Third, the rebate application is submitted with the required documentation, which typically includes your invoice and confirmation of your heating source. Enbridge Gas customers usually receive the rebate as a bill credit, while homeowners who heat with electricity, oil, propane, or wood typically receive a cheque. Processing generally takes several weeks after a complete application is submitted.
Because the program is scheduled to end on November 30, 2026, and can end earlier if funding is exhausted, the practical advice is to start the process well before the deadline rather than waiting until the fall.

How much is the Ontario attic insulation rebate in 2026? The rebate covers 50% of your total attic insulation cost after tax, up to a maximum that depends on your existing insulation level: up to $1,250 if your attic is currently at R-12 or below, up to $1,000 for R-12 to R-25, and up to $800 for R-25 to R-35. In all cases you must upgrade to R-50 or higher and insulate 100% of the accessible attic. The rebate is delivered through the Ontario Home Renovation Savings Program and is confirmed through November 30, 2026.
Do I need a home energy assessment to get the attic insulation rebate? No. The standalone attic insulation path under the Home Renovation Savings Program does not require a home energy assessment. Your existing insulation level is confirmed during the contractor’s in-home estimate, which quality contractors provide at no separate cost. This is what makes the attic rebate one of the simplest energy rebates currently available to Ontario homeowners.
Who qualifies for the attic insulation rebate in Ottawa? To qualify, you must own the home (renters are not eligible), it must be an eligible property type (single-detached, semi-detached, row house, non-stacked townhome, or mobile home on a permanent foundation), and it must be heated either with Enbridge natural gas or with electricity, oil, wood, or propane connected to an eligible Ontario electric utility. Your existing attic insulation must be R-35 or below, you must upgrade 100% of the accessible attic to R-50 or higher, and the home must not have previously received this rebate.
When does the Ontario attic insulation rebate expire? The Home Renovation Savings Program, including the attic insulation rebate, is confirmed through November 30, 2026. Enbridge Gas reserves the right to end the program early if funding is exhausted. Because of this, homeowners considering an attic insulation upgrade should begin the process well before the deadline rather than waiting until the final weeks.
Can I combine the attic insulation rebate with a roof replacement? Yes. The attic insulation rebate is a standalone rebate based on the insulation work itself, so it can be claimed whether or not you are also replacing your roof. Combining the two is often practical because the roof, attic insulation, and attic ventilation work together as a system. Addressing them at the same time means the full system starts fresh, and you recover part of the insulation cost through the rebate in the same project window.
