How much does it cost to replace one window in Canada?
In Home Cost Canada’s Canada-average editorial calculator, replacing one standard energy-efficient window using a full-frame installation and no opening changes produces a planning range of about C$690–C$1,600. This is a mathematical output of the model, not a verified contractor quote or a published industry average. It excludes sales taxes and hidden frame or wall repairs. A one-window job can also face minimum visit charges.
Calculate your own window replacement range by entering the count, location, frame choice, installation type and opening changes.

List every opening
Record approximate width, height and operating style. A small fixed window, casement, slider, bay and egress window should not share one assumed unit price.
Insert and full-frame are different scopes
An insert installation retains more of the existing frame. Full-frame replacement can address frame condition and change exterior/interior finishing, but usually requires more labour and materials.
Glazing and performance need specifications
Ask for the exact glass package, coatings, spacers, frame material and performance rating. For energy decisions, use product documentation and an EnerGuide evaluation rather than a generic savings promise.
Opening changes need separate review
Enlarging or relocating an opening may involve structure, cladding, interior repair and permits. The calculator only applies a broad factor; it cannot inspect a wall.
