Window Installation Cost in 2026: Toronto and Ontario CAD Prices
GTA installed prices by window style and frame from Window Force and RenoHouse, whole-house budgets, labour adders, HomeGuide US benchmarks, ENERGY STAR rules, permits and the Ontario window rebate.
A replacement window costs $400 to $2,000 or more installed in the GTA in 2026, according to Window Force's Toronto cost guide, before tax. Window installation means removing the old sash or frame, setting and shimming the new unit, then insulating, sealing and trimming the opening. Most quotes depend on the style, the frame material and whether the installer keeps the old frame. To get local prices, start with our window installation services.

How much does a replacement window cost in Toronto by style?
A replacement window in Toronto costs $400 to $900 for a fixed picture window and up to $5,500 for a bow window, installed, says Window Force. Opening styles cost more than fixed ones because of the hardware and seals. Casement and awning windows run $600 to $1,400 each, and sliders start at $500.

Do you need a permit or qualify for a rebate in Ontario?
A same-size window swap in a Toronto house needs no permit, but a new, enlarged or moved opening does. The City of Toronto exempts replacing a window in an existing opening of a detached, semi-detached or single-unit row house, if the size and structure do not change and no new exit is made (City of Toronto).
- Rebate: Home Renovation Savings pays $100 per rough opening for ENERGY STAR certified windows, with a minimum of three windows (Home Renovation Savings).
- Catch: You need a home energy assessment before work starts. The program refunds $600 for the assessments.
- Bundle: Three qualifying upgrades earn an extra $500 rebate on the same program page.
- ENERGY STAR bar: Natural Resources Canada requires a U-factor of 1.22 W/m²·K or lower, or an Energy Rating of 34 or more, and air leakage of 1.5 L/s/m² or less (NRCan).
Window Force lists typical double-pane U-factors of 1.4 to 1.8 and triple-pane U-factors of 0.8 to 1.2, so check the label before you count on the rebate. Pairing windows with attic insulation is one way to reach three upgrades. See our attic finishing statistics for the attic rebate bands.
How do you get an accurate window installation quote?
Count your windows by style, measure each rough opening and note the floor and wall type. Ask for an itemized written quote that names the product, frame material, glass package, U-factor and install method. Confirm WSIB clearance and liability insurance, and ask whether the model is ENERGY STAR certified.
Compare free quotes through our window installation hub, or start from a city page such as window installation in Vaughan. If windows are part of a larger job, our general contractor cost guide and the best general contractors in Hamilton list can help you plan it.
