If you’re searching for free Canadian government grants for window replacement, you’re not alone. Rising energy bills and cold winters make old windows expensive fast. While truly “free” federal grants are now limited, several government programs can still cover a large portion of your window replacement costs — especially when combined with provincial rebates and interest‑free loans.
Most Canadian government programs no longer pay 100% of window replacement costs upfront. Instead, funding usually comes as:
In some cases, low‑income households can still replace windows at little or no out‑of‑pocket cost once programs are combined.
The Canada Greener Homes Grant officially closed to new applicants in February 2024. It previously offered up to $5,000 in non‑repayable grants, including:
This program is no longer available, but many homeowners still confuse it with active options.
While not a grant, this is the most important federal support still active.
What it offers
Window eligibility
This loan can effectively make window replacement “feel free” in the short term, since you avoid interest costs entirely.
The Oil to Heat Pump Affordability program is designed for lower‑income households switching off oil heating. Window replacement is eligible only when tied to broader energy upgrades.
Key details
Funding levels vary by province and income, but for eligible households, window upgrades may be fully covered as part of the retrofit package.
Since federal grants are limited, provincial programs now do most of the heavy lifting.
Examples include:
Rebate amounts usually range from $50 to $250 per window, depending on efficiency rating and province.
Tools like GrantHub’s eligibility matcher can help you filter window replacement programs by province, income level, and home type in seconds.
To reduce your cost as close to zero as possible:
In some provinces, stacking programs can cover 60–90% of total costs.
Replacing windows before an energy audit
Retrofits done early usually don’t qualify for rebates or loans.

Buying non‑eligible windows
ENERGY STAR® certification is mandatory for most programs.
Missing provincial deadlines

Q: Are there truly free Canadian government grants for window replacement?
Not fully anymore. Most programs offer partial rebates or interest‑free loans, but low‑income households may still qualify for near‑zero‑cost upgrades when programs are combined.
Q: Can renters apply for window replacement grants?
Generally no. Most programs require the applicant to be the homeowner, though landlords may qualify under separate energy efficiency programs.
Q: Do windows need to be replaced all at once?
Not always. Some programs allow phased upgrades, but funding caps still apply per household.
Q: Are window grants available for businesses?
This page focuses on residential programs. Businesses should look at separate commercial energy efficiency incentives.
Free Canadian government grants for window replacement are more limited than they used to be, but funding hasn’t disappeared. The right mix of provincial rebates and federal interest‑free loans can still make upgrades affordable.
