Windows and doors are a small part of a wall but a large part of its heat loss, and the rebates that pay for them set strict rules on certification and glazing.
Tell us about your property and get quotes from installers near you for:
For homeowners replacing old, drafty or failed windows, and for deeper retrofits that also add insulation and a heat pump.
For offices, retail and apartment or condo buildings, where the work is bigger and the glazing is often commercial-grade.
Commercial and multi-unit buildings use different incentive programs from houses, and the rules vary by utility. Ask your installer and your utility before you order.
ENERGY STAR windows must meet an energy rating (ER) or a maximum U-factor set for one of three climate zones, and must leak no more than 1.5 litres of air per second per square metre. NRCan says certified products cut annual energy costs by about 8% against conventional ones.
| Zone | Heating degree-days | Minimum energy rating | Or maximum U-factor (W/m²·K) |
|---|---|---|---|
| Zone 1 | Under 3,500 | 25 | 1.60 |
| Zone 2 | 3,500 to under 6,000 | 29 | 1.40 |
| Zone 3 | 6,000 or more | 34 | 1.20 |
U-factor measures how fast heat escapes, so a lower number is better. The energy rating also counts air leakage and the heat a window gains from the sun, so a higher number is better. A product that qualifies for Zone 3 also qualifies for Zones 1 and 2, and every certified product carries a label that names its zone or zones.
Rebates can ask for more than the label. BC's program wants a U-factor of 1.22 W/m²·K or less, and Manitoba's wants ENERGY STAR certified windows with at least triple-pane glass.
Get an energy audit before you decide. NRCan estimates windows and doors account for up to 25% of a home's heat loss and air leakage for about another 25%, and sealing and insulating are usually the cheaper first steps. Replace windows when they are failing, not only to save energy.

Figures from NRCan's Keeping the Heat In. The order matters for the rest of the house too: do the envelope first and you can fit a smaller, cheaper heat pump later.
Price depends on how many openings you replace, their size, the frame material and glass package, and how much carpentry the install needs. Triple-pane glass, custom shapes and full-frame installs cost more than standard sizes and insert installs. Rebates of $100 per window or door in BC, Manitoba and Ontario cover part of it.
BC, Manitoba and Ontario each pay $100 per window or door, and BC caps its rebate at $2,000 per home. Income-qualified households can ask their province's delivery partner for the federal Greener Homes Affordability Program whether windows and doors are included. Each program has its own glazing and certification rules, so check them before you order.
The Greener Homes Grant is closed to new applicants, the Greener Homes Loan closed on Oct 1, 2025, and the Oil to Heat Pump Affordability program stopped taking applications on July 31, 2026. What replaced them: the no-cost Canada Greener Homes Affordability Program for income-qualified households, and the provincial programs below. Read the full rundown.
Low-to-median-income homeowners and tenants
No-cost retrofits for income-qualified households. Which upgrades are covered depends on your province's delivery partner, so ask whether windows and doors are included

Some cities and utilities lend for energy upgrades and collect the repayment on your property tax or utility bill, so you pay nothing up front. A loan has to be paid back with interest, so check the rate and the fees first.

Yes, in the programs listed above. BC and Manitoba pay $100 per door and Ontario pays $100 per rough opening for windows and doors. Doors must replace one between heated and unheated space, and the glazed ones need ENERGY STAR certification. Manitoba exempts entry doors with no glass from its triple-pane rule.
Ask your municipality before you start. Swapping a window in its existing opening is often treated differently from enlarging, moving or adding an opening, which can change the structure and may need a building permit. Condo and heritage-district owners may also need approval from their board or the city.
Choose an installer who quotes the brand, model, U-factor and ENERGY STAR zone in writing, states the installation method, and says who handles the old units, trim and permit. Compare at least three quotes for the same scope, and check each against your rebate's rules before you sign.

Enter your address. Window rebates differ on glazing, certification and caps, and Ontario's pays only with an energy assessment.
Ontario's assessment stream needs an assessment before work starts. An audit also shows whether windows are worth replacing yet.
Each installer measures the openings and quotes named models. Check the U-factor and ENERGY STAR zone against your rebate.
Custom units can take weeks. The installer fits, flashes and seals each opening and removes the old units.
Keep the invoice with model numbers, the proof of payment and the certification numbers. Programs set deadlines, such as 90 days in Manitoba and 6 months in BC.
Submit the invoice and product details to the program before its deadline.

Answers checked against government and official program pages.
Yes, from provinces and utilities. BC pays $100 per window or door up to $2,000 per home, Manitoba pays $100 per qualifying window or door, and Ontario pays $100 per rough opening when you do an energy assessment and at least two upgrades. Income-qualified households can also ask their province's delivery partner for the federal Greener Homes Affordability Program whether windows and doors are covered.
The window meets an energy rating or a maximum U-factor for one of three Canadian climate zones, and leaks no more than 1.5 litres of air per second per square metre. The label names the zone or zones it qualifies for. NRCan says certified products cut annual energy costs by about 8% compared with conventional ones.
It depends on your zone and your rebate. Zone 3, the coldest, needs an energy rating of 34 or a U-factor of 1.20 or less. Manitoba's rebate requires at least triple-pane glass, and BC's requires a U-factor of 1.22 or less. Ask each installer for the U-factor of the models they quote.
Usually not. Windows and doors account for up to 25% of a home's heat loss, but air leakage is about 25% too, and air sealing and insulation are generally the cheaper first steps. An energy audit ranks the upgrades for your home. Replace windows now if they are rotted, won't close or have failed seals.
In Ontario's Home Renovation Savings Program, yes: the stream that pays $100 per window or door requires an energy assessment before work starts and at least two qualifying upgrades. BC and Manitoba pay their window rebates under separate rules, so read each program's page before you book.
The number and size of the openings, the glass and frame, how much carpentry the install needs, and finishing work. Insert installs cost less than full-frame replacements, and custom shapes and triple-pane glass cost more. Compare at least three written quotes for the same scope.
Manitoba wants your application within 90 days of installation and full payment. BC wants it within 6 months of the invoice date. Ontario asks you to complete the program's assessment and upgrades first. Keep your invoice, proof of payment and product certification numbers.
