Window Replacement in 2026: Energy Rebates and What GTA Homeowners Should Budget
Current rebate programs, average costs per window, and how to choose between vinyl, fiberglass, and aluminum frames.
Average Window Replacement Costs in the GTA
Single window replacement runs $600–$1,200 installed depending on size, frame material, and glass package. Full-house replacement (10–15 windows) typically ranges from $8,000 to $18,000.
Available Rebates for 2026
The Canada Greener Homes Grant offers up to $5,000 for energy-efficient upgrades including windows. ENERGY STAR certified triple-pane windows qualify for the highest rebate tier.
Vinyl vs Fiberglass vs Aluminum
Vinyl remains the most popular choice in the GTA due to cost and thermal performance. Fiberglass offers superior durability and a slimmer profile but costs 20–40% more. Aluminum is best for commercial or modern architectural styles.
