What's the maximum rebate amount per window from Greener Homes?

The Canada Greener Homes Grant provides up to $250 per window for eligible ENERGY STAR certified window replacements, with a maximum total of $5,000 for all windows in your home.

To qualify for the full $250 per window rebate, your new windows must meet specific performance criteria. They need to achieve a U-factor of 1.22 W/m²·K or lower and be ENERGY STAR certified for Canada's northern climate zones. In Ottawa's Climate Zone 6, this typically means triple-pane windows with Low-E coatings and argon gas fill will easily meet these requirements, while some high-performance double-pane windows may also qualify.

The rebate process requires both pre and post-retrofit EnerGuide evaluations by a certified energy advisor, which costs around $600-800 total but is partially covered by a separate $600 grant. You'll need to complete the pre-evaluation before starting your window project and the post-evaluation within 18 months of the pre-evaluation date.

For Ottawa homeowners, this rebate can significantly offset the cost of quality window replacement. With typical premium triple-pane windows costing $600-1,200 installed, the $250 rebate represents substantial savings. The program also stacks with other incentives - some utility programs and municipal rebates may be available for additional savings.

Important timing consideration: You must receive your pre-evaluation and be enrolled in the program before purchasing or installing your windows. The rebate is paid after completion and the post-evaluation confirms the work meets program requirements.
