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.
Ottawa's renovation market benefits from a stable economy anchored by the federal government. Contractor availability is better than Toronto, with wait times of 2–5 weeks in peak season. The Glebe, Westboro, and Old Ottawa South have high concentrations of century homes requiring specialized heritage renovation skills. Cross-border shopping in Gatineau can save on some materials due to Quebec's different pricing.
Ottawa requires building permits for structural changes, new plumbing, electrical upgrades, and additions. Applications are submitted through the City's 311 service or online portal. Standard residential permits take 10–20 business days. Homes in heritage conservation districts require additional Heritage Planning approval.
Ottawa has one of the widest temperature ranges in Canada (-14°C in January to 27°C in July). The heavy snowfall (average 175 cm/year) puts extra demands on roofing and requires consideration for ice dam prevention. Spring flooding risk near the Ottawa River can impact basement renovation decisions.
