Key takeaways
- Most window installation & replacement jobs in Canada land between CA$500–CA$16,000 — known locally as window replacement.
- Canadian window replacement is governed by provincial building codes (egress, glazing safety) with permits required in many municipalities for full-frame changes. ENERGY STAR Canada zones drive spec, and periodic federal/provincial rebate programs reward efficient replacements — worth checking before ordering.
- Prices below are researched national ranges, updated July 2026 — not quotes.

What affects the price
- Job size and scope — bigger or more complex jobs move you up the ranges above.
- Access and condition — hard-to-reach areas, older properties or neglected maintenance add labour time.
- Materials and quality level — where materials are involved, the grade you choose often matters more than labour.
- Urgency — same-day or out-of-hours work usually carries a premium.
- Where you live — large metros in Canada typically run above the national range; smaller towns below it.
How to save
- Get at least three quotes and compare like-for-like scopes, not just totals.
- Be flexible on timing — off-peak slots are often cheaper.
- Bundle related tasks into one visit to spread call-out costs.
- Agree the scope in writing up front to avoid change-order surprises.

Frequently asked questions
What is double glazing and is triple glazing worth it?
Double glazing (two panes with a sealed gas gap) is the modern default. Triple adds insulation and noise benefits that matter most in cold climates and on noisy roads; elsewhere the extra cost rarely pays back. Spend first on installation quality and low-E coatings — a badly fitted triple-glazed unit performs worse than a well-fitted double.
Can windows be replaced in winter or bad weather?
Yes — pros replace one opening at a time so the house is never fully open, and cold-weather installation is routine in cold climates. Sealants and foams have temperature limits, so extreme cold or rain may shift a schedule, but winter is often the quieter, cheaper season to book.
How long does window installation take?
Replacing a window in an existing opening takes 2-4 hours per window for an experienced crew — a whole house is usually 1-3 days. The wait is in manufacturing: made-to-measure windows typically take 2-8 weeks from survey to fitting.
How do I choose between vinyl/uPVC, aluminium and timber windows?
uPVC/vinyl is the value pick: good insulation, low maintenance, mid-range look. Aluminium gives slim frames and durability (thermally broken frames fix its insulation weakness) at a higher price. Timber looks best and suits period homes but needs maintenance and costs most. Warranty and installer quality matter more than brand marketing.
How much does window replacement cost?
Windows are priced per opening: the unit itself (frame material, glazing spec, size) plus installation labour. A standard-size replacement in an existing opening is the base case; enlarging openings, upper-floor access, bay windows and heritage styles add meaningfully. Whole-house jobs get per-window discounts.
What should a window installation quote include?
Per-window pricing with glazing spec, removal and disposal of old windows, making good internal reveals and external sealing, hardware, and warranty terms for both the unit (often 10 years) and the installation. Cheap quotes commonly exclude making-good — the messiest part.
Do new windows need planning permission or permits?
Like-for-like replacement is usually permit-free, but many places regulate windows through energy codes, safety-glass rules, and egress requirements for bedrooms — and heritage/conservation properties almost always need consent for changes. Your installer should know local rules; ask what paperwork you'll receive at completion.
Is triple glazing worth it in Canada?
In most of Canada, yes or nearly — the climate justifies triple-pane far more than in milder markets, and many rebate programs favour it. In coastal BC, high-quality double with low-E often suffices; on the Prairies, triple is close to default.
