What documents do I need to apply for window rebates?

Most window rebate programs in Ottawa require energy efficiency documentation, proof of purchase, and professional installation certificates. The specific documents vary by program, but here's what you'll typically need to gather.

For the Canada Greener Homes Grant (up to $5,000 for windows), you'll need a pre-retrofit EnerGuide evaluation, receipts showing ENERGY STAR certified windows were purchased, proof of professional installation, and a post-retrofit evaluation. The windows must meet specific performance criteria - typically a U-factor of 1.22 or lower and an Energy Rating (ER) of 25 or higher.

Enbridge Gas rebates require similar documentation but focus on natural gas savings. You'll need receipts for qualifying ENERGY STAR windows, professional installation certificates, and sometimes before/after photos. The rebate amount depends on the number of windows replaced and their efficiency ratings.

Provincial and municipal programs may have additional requirements. Some require building permits for certain installations, though most window replacements in existing openings don't need permits in Ottawa. Keep all invoices showing the window specifications, installation dates, and installer license numbers.

Documentation tips for Ottawa homeowners: Always request detailed invoices that specify the window model numbers, ENERGY STAR ratings, and U-factors. Professional installers should provide installation certificates. Take photos before, during, and after installation. Many rebate programs have strict timelines - typically you must apply within 6 months of completion.

The key is starting the rebate application process before beginning work, as some programs require pre-approval.
