How much you get
It won't qualify alone
Windows and doors are part of the assessment-required tier alongside insulation, water heater, and air sealing — you need at least 2 upgrades from that group total, and completing 3+ earns an extra $500 bonus.
What's different about doing this in Greater Sudbury
Greater Sudbury Hydro and Enbridge Gas don't offer a separate window/door incentive, and the City's retrofit-financing study (the one funded by the $170,000 grant mentioned on the hub page) hasn't produced a live program to stack on top of this rebate. What does matter locally: Greater Sudbury's climate is significantly colder than southern Ontario's, so window and door air leaks show up faster in a heating bill here, and assessors tend to flag this category more often as part of a broader insulation or air-sealing project.
How to claim it
- Book the pre-retrofit assessment with a registered energy advisor ($600, refunded later).
- Get the report and confirm which openings need replacing to hit an eligible ENERGY STAR rating.
- Complete the window/door work plus at least one other qualifying upgrade.
- Book the follow-up assessment; the rebate arrives by mail within about 60 days.

Common questions
Are window and door rebates available in Greater Sudbury?
$100 per rough opening for an eligible ENERGY STAR-rated window or door, part of the assessment-required tier alongside insulation, water heater, and air sealing — at least one other upgrade from that list is required alongside it.
Do all new windows qualify for the rebate in Greater Sudbury?
No. Given how much colder Greater Sudbury runs than southern Ontario, this is one place a marginal ENERGY STAR rating is more likely to get flagged during the assessment — a basic double-pane replacement generally won't qualify on its own.
Your utility: Greater Sudbury Hydro
Greater Sudbury Hydro distributes power across a service area that's geographically enormous for an Ontario city — Greater Sudbury's municipal boundaries stretch over hundreds of square kilometres of mixed urban and rural land, which can mean a longer wait for a service truck in the outer areas than downtown. The windows and doors rebate amount doesn't change based on that; it's set provincially. Where it matters is timing: if your installer needs a service upgrade signed off before your window and door work closes out, build in extra lead time if you're outside the urban core.
What Greater Sudbury's winters mean for this upgrade's payback
Greater Sudbury is genuinely northern Ontario, and it shows in the numbers: the 10-year average January daily low (2015-2024) is -15.2°C, with a coldest recorded day of -35.9°C — cold enough that a poorly sealed rough opening isn't a minor inefficiency, it's a real hole in the building envelope for four or five months a year. Homes here tend to have already dealt with insulation basics; windows and doors are often the remaining weak point.
