How much you get
Windows & doors
Per rough opening replaced with an eligible ENERGY STAR window or door.
This rebate is part of the assessment-required tier: it needs a home energy assessment (about $600, refunded as a rebate), at least two qualifying upgrades, and an extra $500 bonus for completing three or more upgrades.
Pair it with other assessment-tier upgrades
Windows and doors are one of several measures in the same tier as exterior wall insulation (up to $3,600), foundation/basement wall insulation (up to $1,500), crawlspace insulation (up to $2,400), exposed floor (up to $300), heat pump water heater ($500), and air sealing ($200–$250). Combining several of these gets you the $500 completion bonus.

Your utility: Utilities Kingston
Kingston is unusual among mid-size Ontario cities in that one municipally-owned agency, Utilities Kingston, handles electricity, water, wastewater and gas billing together rather than electricity being split off into its own separate company. That doesn't change your windows and doors rebate math, since the payment is fixed provincially, but it does mean a single phone call covers most utility-side questions if your renovation touches more than one service line.
What Kingston's winters mean for this upgrade's payback
Kingston sits where Lake Ontario narrows into the St. Lawrence River, a geography that brings sharp wind off open water in winter even though the lake itself moderates the average temperature — the 10-year average January daily low (2015-2024) is -9.0°C, with a coldest recorded day of -29.2°C. Wind-driven cold is precisely what exposes a poorly sealed rough opening, since it's air infiltration through gaps, not just still-air heat loss, that a drafty old window struggles with most.
