New windows are one of the few upgrades that look better, feel better, and cut your energy bills at the same time. But pricing is confusing — quotes are usually per window, and the range is wide because frame material, glass, and installation quality vary so much.
Here’s what replacement windows cost in 2026 and how to choose ones worth the money.
2026 cost per window
Installed cost per window, including labour:
- Vinyl (most popular): C$620–C$1,400 per window.
- Fibreglass or composite: C$960–C$2,100 per window.
- Wood or clad-wood: C$1,200–C$2,700+ per window.
- Whole-home (10–15 windows): C$8,200–C$24,500 depending on material and size.
What drives the price
Two quotes can differ a lot because of:
- Frame material — vinyl is the value pick; fibreglass and wood cost more.
- Glass package — double vs. triple pane, low-E coatings, and gas fills for efficiency.
- Window size, shape, and count.
- Install type — a simple "insert" replacement costs less than a "full-frame" replacement that rebuilds the opening.
- Structural repairs — rotted framing found during removal.
Choosing efficient windows
Look for the ENERGY STAR label and check two numbers: the U-factor (lower = better insulation) and the Solar Heat Gain Coefficient (lower keeps summer heat out; a higher value can help in cold climates). The right targets depend on your climate zone — a good installer will recommend a glass package suited to your region.
Efficient windows can trim heating and cooling bills and may qualify for 2026 energy tax credits, which improves the payback. Ask your installer to identify current incentives.
What’s different in Canada
Prices on this page are in Canadian dollars and reflect typical national ranges; your province and city matter a lot. Labour and materials run higher in the GTA, Vancouver and Calgary than in the Prairies or Atlantic Canada, and remote/northern communities add freight and travel.
Most trades and larger renovations need a municipal building permit, and electrical and gas work must be done by (or inspected for) a licensed/certified tradesperson under the provincial code — an ESA permit in Ontario, Technical Safety BC out west, and so on. Budget for GST/HST (and PST where it applies) on materials and labour, and factor cold-climate details like insulation, ice-dam protection and freeze-safe plumbing.

Frequently asked questions
Are new windows worth the cost?
They improve comfort, cut drafts and noise, lower energy bills, and boost curb appeal and resale — a strong all-around return, especially if your current windows are single-pane or failing.
Insert vs. full-frame replacement?
Inserts fit into the existing frame and cost less — great when the frame is sound. Full-frame replacement rebuilds the opening and is the right call when there’s rot or you’re changing size/shape.
How long does window installation take?
A crew can often replace 10–15 standard windows in 1–2 days. Custom sizes and full-frame work take longer.
Do new windows qualify for tax credits?
Energy-efficient windows meeting ENERGY STAR criteria frequently qualify for federal tax credits in 2026, plus some utility rebates. Confirm current limits with your installer or tax advisor.
