Window Replacement Cost in Canada: What to Expect (2026)

Window Replacement Cost Overview

Replacing windows in a Canadian home costs between $5,000 and $25,000+ in 2026, depending on the number of windows, material, and style. Energy-efficient windows can reduce heating costs by 15-25%, making them one of the smartest upgrades for Canadian climates.

The average Canadian home has 10-15 windows. Replacing all of them at once is usually more cost-effective than doing a few at a time. Use our window replacement calculator for a personalized estimate.

Cost by Window Material

Material	Cost per window (installed)	Lifespan	Energy Efficiency
Vinyl	$400 - $800	20-30 years	Good — low-E glass standard
Wood	$800 - $1,500	30-50 years	Excellent — natural insulator
Fiberglass	$700 - $1,300	30-50 years	Best — minimal expansion/contraction

Vinyl windows dominate the Canadian market due to their excellent value and low maintenance. Triple-pane glass is recommended for homes in Ontario, Quebec, and the prairies for maximum energy savings.

• Glass type — Triple-pane costs 25-40% more than double-pane but offers superior insulation.
• Frame condition — If the frame is rotted or damaged, a full-frame replacement is needed versus an insert, adding $100-$300 per window.
• Low-E coating — Standard on quality windows. Argon-filled glass adds $25-$50 per window for better insulation.
