Searching "Ontario window rebate" still surfaces programs that closed years ago alongside the one that's actually active, which is why so many homeowners start a rebate conversation with outdated assumptions. Here's what's real right now, and how the pieces fit together if you're planning more than one upgrade.
What's actually open right now
The Home Renovation Savings™ program is the current active incentive covering ENERGY STAR® certified windows, doors, and attic insulation upgrades, offering rebate amounts per eligible unit or rough opening when two or more qualifying upgrades are bundled into one project. A pre-work energy assessment is part of the process, confirming the home's current condition before work begins.
What's closed, and why it still shows up in searches
The Canada Greener Homes Grant and the Enbridge Home Efficiency Rebate Plus both drove years of search traffic and are frequently still referenced by older articles and even some contractors, but neither is accepting new applications. If a quote or a conversation references either program as currently available, that's a sign the information is out of date.
Why bundling changes the math
Applying for a rebate on a single window replacement is possible, but the per-unit or per-opening amount is the same whether it's bundled or not — what bundling actually changes is whether the project clears the minimum threshold to qualify at all, since some program tiers require multiple upgrade categories in one application. Homeowners planning both windows and attic insulation, even on different timelines, often get better results submitting them as one bundled application rather than two separate ones.
The energy assessment isn't optional, and timing matters
The pre-work assessment has to happen before work starts, not after — a common and costly mistake is completing a project first and trying to apply for the rebate afterward, which typically doesn't qualify. Scheduling the assessment early in the planning process, before materials are ordered or installation is booked, keeps the whole timeline moving in the right order.
Where this fits with financing
Rebate amounts are typically issued after project completion and verification, not upfront, so most homeowners finance the full project cost and treat the rebate as a reduction to the balance once it arrives rather than a discount applied at time of purchase.
