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.

Common questions
Are window and door rebates available in Oakville?
Yes, through the same provincial HRSP structure used across Ontario — $100 per rough opening, bundled with insulation or another qualifying upgrade. Oakville Hydro's own Retrofit Program can also cover a share of eligible window and door costs, separate from HRSP, through a utility application.
Do all new windows qualify for the rebate in Oakville?
No. They need to meet ENERGY STAR's rating for your climate zone. A standard double-pane replacement usually won't qualify on its own, and Oakville Hydro's Retrofit Program has its own separate eligibility list if you're applying to that as well.
Your utility: Oakville Hydro
Oakville Hydro remains a standalone, town-owned utility rather than part of Alectra or one of the other regional mergers that consolidated many of its GTA neighbours. That independence has no bearing on your windows and doors rebate amount, which the province sets the same way for every Ontario homeowner, but it does mean Oakville-specific service requests (a panel check, a new connection) go through a smaller, local operation.
What Oakville's winters mean for this upgrade's payback
Oakville's Lake Ontario shoreline position gives it winters on the milder end for the GTA, with a 10-year average January daily low (2015-2024) of -6.8°C and a coldest recorded day of -27.0°C. A lot of Oakville's older housing stock predates the 1980s energy-efficiency building code changes, so even in a comparatively mild climate, original wood-frame windows from that era are usually losing more heat than the outside temperature alone would suggest.
