What the program is.
The Home Renovation Savings Program is Ontario's main energy-efficiency rebate program for homeowners. It is delivered by Enbridge Gas and Save on Energy with support from the Government of Ontario, and covers a range of upgrades — insulation, air sealing, heat pumps, smart thermostats, and the one this guide is about: windows and exterior doors.
For windows and doors, the headline number is simple: $100 back per rough opening when you replace old units with ENERGY STAR® certified models. A rough opening is the structural hole in the wall — one window or one exterior door equals one opening. Replace twelve windows and a front door, and that is thirteen openings.
Program details are set by the provider and may change. The rebate amount, assessment, bundle and minimum-opening rules were rechecked on 3 October 2026. Confirm eligibility and current rules at homerenovationsavings.ca before you count on a rebate. This is a third-party incentive program; Maximum Quality does not offer financing.

The fine print: it's a bundle.
This is the part most window advertising quietly skips. Window and door rebates sit in the program's bundled stream, which means replacing windows alone does not qualify. To unlock the per-opening rebate you need to:
1. Book a home energy assessment with a registered energy advisor before any work starts. The advisor audits your home, recommends upgrades and documents its starting condition. A follow-up assessment after the work verifies what changed — and the program offers an incentive toward the cost of the assessments themselves.
2. Complete at least two qualifying upgrades. Windows or doors can be one of them; insulation and air sealing are the most common partners, and often make sense to do at the same time anyway — new windows in a leaky wall only solve half the problem.
3. Use ENERGY STAR® certified products. When comparing vinyl windows or entry doors, ask our team for certification details for the exact model on your quote. Do not assume every configuration qualifies.
If you want the deeper background on what makes a window ENERGY STAR® certified in the first place — Low-E coatings, argon fill, glazing layers — our energy-efficient windows guide walks through it in plain English.
Three steps, in order.
The order matters — book the assessment before any windows come out, or the rebate is off the table.
Assess first
Register with the program and book your home energy assessment before starting any work. Keep the report — it defines what your project can claim.
Do the upgrades
Complete your bundle — for example, ENERGY STAR® windows plus attic insulation. Keep all invoices and product certification labels.
Verify & get paid
The follow-up assessment confirms the work, you submit your claim through the program, and the rebate is paid out per documented opening.
Is it worth the paperwork?
For a typical whole-home replacement — ten to fifteen openings — the rebate lands in the $1,000–$1,500 range, plus the assessment incentive and whatever your second upgrade earns. On a project you were doing anyway, that is meaningful money for a few appointments and some paperwork. For a single window, the minimums rule it out — the program requires at least three window openings (or one door) to participate.
Check the program's availability and deadlines on the official site before you begin. Incentive amounts, funding and eligibility rules can change.
