How Much Does Window Replacement Cost in Canada? (2026 Guide)

Replacing the windows in your home is a major renovation — and one of the most effective ways to boost energy efficiency, comfort, and curb appeal. But before you get started, a key question many Canadian homeowners ask is:

How much will it actually cost?

Let’s break down the real numbers, what influences pricing, and how to budget your window replacement project with confidence.

National Window Replacement Cost Overview

In Canada, window replacement costs vary widely depending on window type, materials, glazing, labour, and location, but typical price ranges (per window) are:

? National Average Cost per Window (Installed):

• Basic entry-level windows: $400 – $800

• Mid-range energy-efficient windows: $600 – $1,200

• Premium or custom windows: $1,000 – $2,000+
  Some specialty or very large windows (like bay or bow) can cost significantly more.

? Total project cost for a whole home: Most Canadian homeowners spend roughly $5,000 – $15,000 for a full replacement of typical 6-10 windows — though larger homes or premium builds can easily exceed this range.

What Influences Window Replacement Costs?

1. Window Type and Size

• Standard windows (like casement, slider, or hung): Often the most affordable.

• Bay or bow windows: Larger, multi-pane configurations cost more due to materials and installation complexity.

2. Frame Material

• Vinyl: Usually the most cost-effective & energy-efficient choice.

• Fiberglass: Higher durability and better insulation but higher cost.

• Wood: Classic look but maintenance and cost are higher.

3. Glazing & Efficiency Features

Energy-efficient upgrades such as double or triple glazing, Low-E coatings, and argon gas fills increase upfront costs — but can significantly reduce heating and cooling bills over time.

4. Installation Type

• Retrofit installation: Replacing only the window sash and frame within an existing frame can be less expensive.

• Full-frame replacement: Removes the old frame too and costs more — but often results in better performance and longevity.

5. Labour & Regional Differences

Labour costs vary by province and city — Ontario and British Columbia often have higher pricing compared to some other regions, largely due to demand and labour rates.

Typical Cost Examples (Per Window Installed)

Note: These figures include typical professional installation but can vary based on site conditions and accessories.

Cost Breakdown (What You’re Paying For)

When budgeting your project, the total cost typically includes:
✔️ Window materials and manufacturing
✔ Professional installation and labour
✔ Removal & disposal of old windows
✔ Insulation, air sealing, and trimming
✔ Optional upgrades (custom colours, hardware, screens)

Is It Cheaper to Replace All Windows at Once?

Yes, in most cases:
➡️ Replacing all windows in one project often lowers the per-window labour cost and may allow suppliers to offer volume discounts.
➡️ A whole-home project can be more efficient and cost-effective than replacing a few windows piecemeal over years.

Quick Tips to Save on Window Costs

• Get multiple quotes from reputable installers.

• Consider energy rebates — some Canadian provinces offer incentives for ENERGY STAR® rated windows.

• Plan for seasonal deals — late winter or early spring can sometimes yield better pricing.

• Choose the right installation type based on your needs and frame condition.

Final Thoughts

Window replacement costs in Canada depend on your home size, window quality, energy efficiency goals, and region, but homeowners can typically expect to budget:

? $400–$2,000+ per window installed
? $5,000–$15,000+ for a standard whole-home project

While it’s a significant investment, new windows can improve comfort, reduce energy bills, and boost your home’s value for years to come.
