The short answer
In 2026, most Canadian homeowners pay $450 to $1,200 per window installed, and $8,000 to $18,000 to do a whole home. The range is wide because three things move the price more than anything else: the frame material, the glass package, and whether it's a retrofit or a full-frame install.
Cost by window material
Vinyl is the value pick and the most popular choice in Canada. Fiberglass costs more but handles freeze-thaw cycles with less expansion. Wood and aluminum-clad sit at the premium end.
- Vinyl: $450–$900 per unit installed
- Fiberglass: $700–$1,400 per unit installed
- Wood / aluminum-clad: $1,000–$2,500+ per unit installed
Why your city matters
Labour rates, permit rules, and climate-driven glass requirements all shift the final number. We break costs down city by city — see the local price tables for Toronto, Edmonton, and Montreal.
Where the hidden costs hide
- Enlarging or adding an opening (may trigger a permit)
- Rotted framing discovered on removal
- Custom shapes and colours
- Disposal of old units and interior/exterior trim finishing
