Window replacement cost in Canada in 2026 runs $450 to $900 per window installed for a standard double-hung vinyl, and $550 to $1,100 for casement. Whether you’re pricing out window replacement in Toronto, Winnipeg, or across Canada, the actual number depends on window type, glass package, frame material, and your city’s labour rates. This guide gives you honest installed-cost ranges by window type, explains what separates a $600 quote from a $1,200 one, and shows you what to look for before you commit to any installer.
Average window replacement costs in Canada (2026)
These are installed costs. They include the window unit, labour, removal of the old window, and basic trim finishing. They do not include structural repairs, custom shapes, or premium glass packages unless noted.
| Window type | Supply only | Installed cost | Notes |
|---|---|---|---|
| Double-hung vinyl | $250 to $550 | $450 to $900 | Most common style in Canadian homes |
| Casement vinyl | $300 to $650 | $550 to $1,100 | Better air seal than double-hung |
| Bay / Bow | $900 to $2,500 | $1,800 to $4,500 | Structural work often required |
| Sliding window | $280 to $600 | $500 to $950 | Common in condos and bungalows |
| Fixed / Picture | $200 to $450 | $350 to $700 | No moving parts, simplest install |
If you’re replacing a standard double-hung window in an existing opening that’s in good shape, you’re looking at $450 to $900 installed. Anything requiring rough opening modifications, rotted framing repairs, or custom sizing will add $150 to $500 per window on top of that.
What drives the price difference
Two quotes for “the same window” can differ by $300 or more. Here’s why.
Frame material
Vinyl is the default for most Canadian homes and the most affordable option. Fiberglass frames run 20 to 40% more than vinyl but outperform it in extreme cold, dimensional stability, and longevity. Wood frames are premium, look great on traditional homes, but require more maintenance and cost significantly more. Most homeowners replacing windows in Winnipeg, Toronto, or Calgary are choosing vinyl or fiberglass.
Glass package
Double pane (two layers of glass, one air or gas space) is standard and meets ENERGY STAR requirements for most Canadian climate zones. Triple pane adds a third glass layer and second gas space, improving the U-factor from roughly 0.30 to 0.18 or better. That upgrade costs $80 to $200 per window. In Winnipeg and Calgary, where winter design temperatures regularly hit minus 25 to minus 35, triple pane often makes financial sense over a 15-year horizon. In Toronto, double pane usually delivers the right balance of cost and performance.
Installation complexity
Windows on the second floor or higher require additional staging. Masonry or brick openings take longer to work around than wood-framed construction. Rotted sills or headers need repair before the new window goes in. Each complication adds labour time, typically $100 to $400 per window.
Cost by city: Toronto, Winnipeg, Calgary
NorthShield operates in all three markets, so we can give you a ground-level view of how prices compare.
Toronto
Toronto labour rates typically run 15 to 25% higher than mid-size Canadian cities. A double-hung vinyl replacement that costs $550 installed in Winnipeg might cost $650 to $700 in the GTA. The good news: the Ontario Home Renovation Savings Program offers $100 per ENERGY STAR certified window, which takes some of the sting out.
Winnipeg
Winnipeg is competitive mid-range for window installation. The bigger cost consideration here is climate performance. Winnipeg’s extreme winters make window quality matter more than anywhere else in southern Canada. Spending an extra $100 to $150 per window on a quality triple-pane unit with a strong warranty pays off when your heating bills are on the line.
Calgary
Calgary labour rates are similar to Toronto for premium installations. Alberta has seen strong demand for window replacements following the cold winters of 2023 and 2024, which has kept installer capacity tight and prices at the higher end of the national range. Manitoba’s Efficiency MB program also offers rebates worth checking if you’re upgrading to triple pane.
When the lowest quote is not the best deal
The cheapest window quotes tend to cut corners in predictable places: thinner frame profiles that warp more easily in cold, warm-edge spacers replaced with aluminum (which conducts cold right through the frame), no gas fill in the IGU, and short or no warranty on the glass seal. A failed IGU seal is a $200 to $400 repair per window, and if the window is only a few years old, you’re looking at an aggravating outcome.
When evaluating quotes, look for:
- ENERGY STAR certification for your climate zone
- Minimum 10-year warranty on the insulated glass unit seal
- Warm-edge spacer technology (not aluminum)
- Argon or krypton gas fill (not just air)
- Written scope of work that includes trim, caulking, and cleanup
How much can you save with better windows?
Windows account for 25 to 30% of home heat loss on average. Replacing single-pane or failed double-pane windows with ENERGY STAR certified units can cut heating and cooling costs by 12 to 24% annually, according to Natural Resources Canada. On a $2,400 annual heating bill, that’s $288 to $576 in savings per year.
The Ontario Home Renovation Savings Program currently offers $100 per window for ENERGY STAR certified replacements, up to a maximum of $5,000. On a 15-window project, that’s $1,500 back in your pocket. Manitoba’s Efficiency MB program covers up to 25% of upgrade costs for eligible improvements including windows. These rebates don’t eliminate the upfront cost, but they change the payback math meaningfully.
Beyond energy costs, comfort improvements are real. Windows that maintain a higher interior surface temperature eliminate the cold-wall effect that makes rooms feel drafty even when the thermostat is set correctly. Many homeowners say the comfort improvement is what they notice most, not the energy bill.
Frequently asked questions
How much does it cost to replace all windows in a house?
A typical Canadian home has 12 to 20 windows. At $500 to $900 installed each, budget $6,000 to $18,000 for a full replacement project. Larger homes with bay or bow windows will push toward the higher end. Many homeowners replace in phases, doing the worst-performing windows first.
Is it cheaper to replace windows in winter?
Yes, many installers offer 10 to 20% off-season discounts from October through February. Just make sure the installation team is equipped for cold-weather work and uses appropriate caulking that cures at low temperatures. A reputable company will have done winter installs before and won’t cut corners on weatherproofing.
How long do new windows last?
Quality vinyl windows last 20 to 30 years. Fiberglass can last 40 or more years. The weakest link is usually the insulated glass unit (IGU), the sealed space between panes, which typically carries a 10 to 20 year warranty. When the IGU seal fails, you get that foggy condensation look between the panes.
Does window replacement increase home value?
Studies suggest you recover 50 to 75% of the cost in resale value. The real payoff is often comfort, lower energy bills, and faster sale time when you list the home. Buyers in colder Canadian markets pay attention to window age and condition when making offers.
What’s included in an installation quote?
A proper quote should include removal and disposal of old windows, supply of new windows, installation labour, interior and exterior trim and caulking, and cleanup. Be wary of quotes that exclude any of these line items, as they often add them back as change orders once the job is underway.
