How much you get
Why this one needs an assessment
Windows and doors bundle into the assessment-required path alongside insulation, water heater, and air sealing. You need at least 2 of those upgrades — completing 3+ earns an extra $500 bonus.
What's different about doing this in Mississauga
There's no window-and-door-specific local incentive layered on top of HRSP in Mississauga — Alectra Utilities and Enbridge Gas don't run a separate glazing rebate, and the Peel Residential Energy Program (the region's joint program with Brampton and Caledon) is a free Home Energy Coach pilot, not a rebate stream. Since most Mississauga homes are already gas-heated and this category requires bundling with at least one other upgrade, the most common pairing here is windows/doors plus attic insulation, since the attic top-up doesn't need its own assessment and can be added to the same visit.
How to claim it
- Book an initial home energy assessment with a registered energy advisor ($600, refunded later).
- Get your custom report and confirm which windows/doors qualify at your ENERGY STAR rating.
- Complete the window/door replacement plus at least one other qualifying upgrade; insulation is the common pairing.
- Book a follow-up assessment, then the rebate arrives by mail within 60 days.

Common questions
Are window and door rebates available in Mississauga?
$100 per rough opening for an eligible ENERGY STAR-rated window or door, as part of the assessment-required tier — you need at least one other qualifying upgrade alongside it, like insulation or a water heater.
Do all new windows qualify for the rebate in Mississauga?
No. They need to meet the ENERGY STAR rating for southern Ontario's climate zone, so a standard double-pane replacement usually won't qualify on its own — check the rating on the product spec sheet before you buy.
Your utility: Alectra Utilities
Mississauga's electricity used to come from Enersource before the 2017 merger that created Alectra Utilities out of Enersource, Brampton Hydro, Horizon Utilities and PowerStream. The windows and doors rebate amount is set provincially and doesn't move based on that history, but Alectra's size as one of Canada's largest municipal utilities means online self-service tools tend to be more built-out than what a small single-city utility offers, which can simplify service-capacity questions if your installer flags one.
What Mississauga's winters mean for this upgrade's payback
Mississauga's lakeside position moderates its winters relative to inland Peel Region, with a 10-year average January daily low (2015-2024) of -7.8°C and a coldest recorded day of -29.0°C. The city's mix of housing stock is wide, postwar bungalows in the older wards sitting next to condo towers and 2000s-era subdivisions, which means the windows and doors rebate is doing very different jobs depending on which part of Mississauga a homeowner is in.
