Window, door & balcony installation

Window, door and balcony installation in Canada

Updated 4 November 2026

Installing a window in Canada costs about CA$400 to CA$900 per window, and an installed patio door about CA$1,500 to CA$5,000, depending on size, frame material and province. These are approximate prices, according to sellers' websites, November 2026. For current prices for your openings, send one request on BlaBlaPrice.

Permits and local rules

Permits depend on the city and on the work. Adding a new opening or turning a window into a door can need a building permit and a zoning certificate; one Toronto example quoted CA$270 to CA$700 for both. In Montreal, the permit fee for adding or replacing doors and windows was listed at CA$9.80 for every CA$1,000 of work, with a minimum of CA$167.40. Ask your installer whether a permit is needed and whether the price includes it. Some installers hold a national installer certification and sign a code of ethics, so you can ask for it.

When to book in Canada

Canada has a cold winter from December to February and a warm summer from June to August. November is late autumn. Cold weather makes sealing and foam work harder, so a deadline in spring or summer is easier to meet than one in January. Say the deadline clearly, because it decides the season the work is done in.

How it is bought in Canada

Prices are quoted per window, per door or per job, and sizes change the price. Measure each opening in millimetres or inches and say which unit you used. Some per-window prices include materials and installation, while others leave the product out, so ask what is included. Quotes differ by city and province, so give yours: Toronto, Montreal, Vancouver, Calgary or Ottawa.

What to write in your request

Name the work (new windows, a patio door or a balcony door), the quantity and the size of each opening. Say who supplies the products and which frame material you want. List extra work such as removing old frames or wall repairs, and add the site address, the deadline and your budget. Those details let each seller give you a comparable offer.
