Quick Window Estimate (Canada)

Preview pricing only. Full calculator adds frame material (vinyl/fiberglass/wood-clad), glass package (low-E argon triple for climate zones 2–3), grille pattern, and install labour at provincial rates.

Built for Canadian Climate & Code

Window pricing tuned to Canadian regulations, brands, and brutal winter conditions.

1

Energy Star Canada Climate Zones

Canada has three Energy Star climate zones (Zone 1 southern BC/Ontario, Zone 2 most of the populated country, Zone 3 far north). Every window spec checks against the correct U-factor and ER rating for the project's climate zone — essential for CHBA rebates and provincial energy programs.

2

Canadian Brand Library

Full cost data for Gienow, Gentek, All Weather Windows, Jeld-Wen Canada, Kohltech, Vinylbilt, Ply Gem Canada, Centra Windows, and Fenplast — Canada's dominant residential window brands — along with American imports from Andersen and Milgard that cross the border.

3

Triple-Glaze as Default

Unlike the US market, triple-glazed argon-filled windows are standard in most of Canada due to winter thermal loss. The calculator defaults to triple-glaze pricing and flags any double-glazed spec with a cold-climate warning — avoiding quote errors that fail Energy Star.

4

Provincial Tax & HST Handling

Canadian tax rates vary wildly — 5% GST in Alberta, 13% HST in Ontario, 15% HST in Nova Scotia, 5% GST + PST in BC. Doorwin applies the right tax rate by project postal code and generates invoice-ready quotes that match provincial requirements.

The Canadian Residential Window Market

The Canadian window market is worth about C$2.3 billion annually, concentrated heavily in Ontario (GTA + Ottawa), Quebec (Montréal + Québec City), Alberta (Calgary + Edmonton), and BC (Greater Vancouver). Vinyl dominates replacement work (~75% market share), with fiberglass gaining ground in premium new construction. Winter performance drives the entire technical conversation.

Doorwin is built for the way Canadian window installers and renovators actually work: brutal climate considerations, strict Energy Star Canada certification (distinct from US Energy Star), heavily regulated provincial labour markets, and significant project spreads between urban Ontario and rural Prairies. The app adapts to metric or imperial, French or English, and province-specific tax.

Frequently Asked Questions (Canada)

Does it handle Canadian Energy Star (not US Energy Star)?
Yes. Canadian Energy Star has its own climate zone map and thresholds — stricter than the US equivalent for cold zones. Every window you spec is checked against the correct Canadian Zone 1, 2, or 3 criteria, and you'll see CHBA rebate eligibility flagged automatically.
Can I quote in French for Quebec projects?
Yes. Quotes for Quebec projects can be generated in French with appropriate terminology (fenêtre à battant, fenêtre à guillotine) and compliant with Loi 101 language requirements. The underlying database is bilingual — toggle at quote time based on client preference.
Are Gienow, All Weather, and other Canadian brands included?
Yes. Gienow, All Weather Windows, Gentek, Jeld-Wen Canada, Kohltech, Vinylbilt, Ply Gem Canada, Centra Windows, Fenplast, North Star, Euro-Vinyl, and more are pre-loaded with cost data. Regional niche brands (e.g., Westeck in BC, Loewen in MB) can be added manually in under a minute.
Does it handle GST/HST/PST properly?
Yes. Tax is calculated by project postal code. BC projects get 5% GST + 7% PST; Ontario and Atlantic provinces get HST at the correct rate; Alberta gets 5% GST only; Quebec gets 5% GST + 9.975% QST. Export aligns with invoice requirements for each province.
