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. Windows and doors are also an eligible measure under the Better Homes Ottawa loan if you're financing the balance.

Common questions
Are window and door rebates available in Ottawa?
Yes. Ottawa homeowners qualify for the same $100-per-rough-opening rebate as the rest of Ontario, and it can be paired with the city's own Better Homes Ottawa loan program if you're financing the work rather than paying upfront.
Do all new windows qualify for the rebate in Ottawa?
No. The window or door needs to carry an ENERGY STAR rating suited to a cold, dry inland climate like Ottawa's, not just any ENERGY STAR label, so double-check the climate zone rating on the spec sheet before your energy advisor's report comes back.
Your utility: Hydro Ottawa
Hydro Ottawa is wholly owned by the City of Ottawa and is one of the largest municipal electric utilities in the province by customer count, serving the urban core out to the rural wards that got folded into the amalgamated city in 2001. The windows and doors rebate itself doesn't depend on Hydro Ottawa at all, since it's a provincial payment, but Hydro Ottawa is your contact for electrical service capacity if a bigger envelope retrofit means your installer needs a panel upgrade, and the rebate can be combined with financing through the Better Homes Ottawa loan program the city runs separately.
What Ottawa's winters mean for this upgrade's payback
Ottawa has one of the coldest, driest winter climates of any major city in Southern or Eastern Ontario: it's far enough from the Great Lakes that there's no shoreline moderation, and the Ottawa Valley funnels cold continental air straight through. That's with a 10-year average January daily low (2015-2024) of -13.2°C and a coldest recorded day of -32.2°C. That's genuinely harsh enough that the payback math on windows and doors tends to be the fastest of any city in this comparison outside the true north.
