Window replacement in Canada should prioritize energy efficiency — look for ENERGY STAR® certified windows rated for your climate zone. Double-pane is minimum; triple-pane is recommended for zones 2 and 3 (most of Canada). Argon or krypton gas fill between panes adds 10–15% to cost but significantly improves insulation. Replace all windows at once if possible — contractors offer better per-window pricing for full-house jobs.
Window frame material is the largest cost factor: vinyl ($400–800/window), fiberglass ($600–1,200), aluminum-clad wood ($800–1,500), and full wood ($1,000–2,000+). Unusual sizes, bay/bow windows, and casement styles cost 30–100% more than standard double-hung. Installation complexity (brick vs. wood siding, second-floor access) affects labour costs.
💡 Pro Tip
Check for federal and provincial rebates before purchasing — the Canada Greener Homes Grant and provincial programs can cover $125–250 per window for ENERGY STAR® upgrades, potentially saving $2,000–$5,000 on a full-house replacement.
Montreal offers moderate renovation costs compared to Toronto and Vancouver, with a large pool of bilingual contractors. The city's distinctive triplex and duplex architecture means many renovations involve shared walls and multi-unit considerations. Quebec's Régie du bâtiment (RBQ) licensing ensures contractor quality but also means only licensed professionals can perform major work.
Montreal requires permits from the borough (arrondissement) for structural modifications, plumbing, electrical work, and exterior changes. Processing times vary by borough — the Plateau and Ville-Marie are typically slower (3–6 weeks). Quebec law requires all contractors performing work over $5,000 to hold an RBQ licence.
Montreal's extreme temperature range (-10°C in January to 27°C in July) demands high-quality insulation and materials rated for severe freeze-thaw cycles. Snow loads are a key factor for roofing projects, and ice dams are common on older homes without proper attic ventilation.
In 2026, a windows renovation in Montreal costs between $4,227 (budget) and $22,218 (premium). The average standard cost ranges from $6,038 to $13,887.
