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.
Hamilton has a lot of older housing stock, including pre-war homes in the lower city with original single-pane or early double-pane windows — those tend to see a bigger improvement (and a stronger rebate case) from replacement than newer suburban builds. Window and door work also qualifies for the city's Local Improvement Charge (LIC) loan, up to $20,000 at a 0% introductory rate repaid through your property tax bill, as part of the building-envelope category alongside insulation.
How to claim it
- Optional: check current LIC loan funding availability if you're financing multiple envelope upgrades together
- Book an initial home energy assessment with a registered energy advisor ($600, refunded later)
- Get your custom report
- Complete the window/door replacement plus at least one other qualifying upgrade
- Book a follow-up assessment; the rebate arrives by mail within 60 days

Common questions
Are window and door rebates available in Hamilton?
Yes, through the same province-wide Home Renovation Savings Program that covers the rest of Ontario: $100 per rough opening for an ENERGY STAR-rated window or door, as long as it's bundled with at least one other qualifying upgrade from the assessment-required tier.
Do all new windows qualify for the rebate in Hamilton?
Not automatically. The product has to carry the ENERGY STAR rating specific to Hamilton's climate zone, and Alectra Utilities doesn't run a separate window verification program, so the rating on the manufacturer's spec sheet is what your energy advisor checks against.
Does Hamilton's LIC loan cover window replacement?
Yes, window and door replacement falls under the building-envelope category the Local Improvement Charge loan covers, alongside insulation and air sealing — up to $20,000 at a 0% introductory rate, repaid through your property tax bill over 10–15 years. It's listed as funding-limited, so confirm current availability with the City first.
Your utility: Alectra Utilities
Hamilton's electricity comes through Alectra Utilities, formed in the 2017 merger that combined the old Horizon Utilities (Hamilton and St. Catharines) with Brampton Hydro, Enersource and PowerStream. The windows and doors rebate is a province-wide payment set by the Home Renovation Savings Program, so Alectra billing you instead of a standalone city utility doesn't change the number. It does matter for logistics: Alectra handles the electrical inspection and connection sign-off if your installer's work touches your home's service panel.
What Hamilton's winters mean for this upgrade's payback
Hamilton benefits from its position on Lake Ontario, which keeps winter lows milder than inland cities at a similar latitude — the 10-year average January daily low (2015-2024) is -6.6°C, with a coldest recorded day of -26.7°C. The Niagara Escarpment running through the city also creates its own microclimates, so a home on the Mountain can see slightly different conditions than one down in the older lower-city neighbourhoods, even a few kilometres apart.
