💬What People Actually Paid
Community❓Common Questions
In 2026, Toronto homeowners typically pay between $600 and $2,500 CAD per window installed. Basic vinyl retrofits start near $600, while premium fiberglass or wood units with full-frame installation average $1,500 to $2,500.
Yes, the Home Renovation Savings Program (HRSP) is active through November 2026, offering $100 CAD per rough opening for ENERGY STAR certified windows. Additionally, the City of Toronto's HELP program provides low-interest financing up to $125,000 for energy upgrades.
Brick-to-brick (full-frame) installation is 20-30% more expensive than retrofit (insert) installation. While retrofits cost $350-$900 per unit, full-frame replacements range from $600 to over $1,500 per window due to increased labor and material for new trim and casings.
Triple-pane windows carry a 20-30% price premium, adding approximately $150 to $300 per unit. However, they can reduce heat loss by up to 40% compared to double-pane, making them a high-ROI choice for Toronto's climate and noise reduction.
