Have you been procrastinating about replacing your windows, not wanting to know how much it will be? You are not alone. One of the most searched questions on home renovation in Toronto is window replacement pricing, and it is rather difficult to find a simple answer to the question, which most companies do.
Here is a simple, sub-breakdown of what Toronto and GTA homeowners are spending on window replacement in 2026, by window type, material, and project size, so you can make a confident budget plan.
Average Window Replacement Cost in Toronto (2026)
Replacement of one window in Toronto generally costs between $400 and $1,200 per window which includes labour and installation fees. When it comes to complete replacement of the house, the average Toronto homeowner is forced to spend between $6,000 and $20,000 or more based on the number of windows to replace, the style, and the material used.
Here’s a quick breakdown by window type:
| Window Type | Average Cost Per Window (Installed) |
|---|---|
| Single slider | $400 – $700 |
| Double slider | $450 – $750 |
| Casement window | $500 – $900 |
| Awning window | $500 – $850 |
| Double hung | $550 – $900 |
| Picture window | $600 – $1,100 |
| Bay or bow window | $1,800 – $5,000+ |
| Basement egress window | $800 – $1,500 |
Note: Prices stated are above those of standard vinyl windows installed professionally within Toronto and GTA. Depending on the window size, frame material, the type of glazing, and the conditions of the site, the price varies.
What Affects the Cost of Window Replacement in Toronto?
Various aspects drive your end cost up or down. Knowing them will assist you in making a fair comparison of quotes.
1. Window Frame Material
One of the largest cost drivers is the material you select:
- Vinyl – Toronto’s most popular. Good insulation, low maintenance, cheap. Price: Cost is ranging between $400 and $900 to be installed per window.
- Fibreglass – More efficient and cost effective compared to vinyl especially in the freezing thaw climate of Ontario. Maintenance expense: $600 to $1200 per window installed.
- Wood – Traditional appearance, good insulation, with more maintenance needs. Cost range: $800–$2,000+ per window installed.
- Aluminum – Slick and shiny but less thermal efficiency in colder weather. Price per window installed: between $500 and 1,100.
Vinyl or fibreglass shows the best balance of performance and value to the majority of Toronto homeowners.
2. Glazing: Double Pane vs Triple Pane
In Toronto, most replacement windows are double-pane (two layers of glass and a sealed gas fill between the layers). Triple-pane windows are 20-30% more expensive in the short term, but have significantly lower heating payments- especially important in GTA winters.
- Double pane (ENERGY STAR): Included in a majority of standard quotes
- Triple pane upgrade: Increases an average of $100-300 per window
3. Number of Windows
Per-unit cost is lowered by installing several windows in a single visit. Contractors have the capability of distributing setup expenses and travelling expenses as well as labour costs throughout the entire work. It is generally 10-20 percent cheaper to replace 10-15 windows simultaneously than to replace them individually.
4. Window Size and Shape
Rectangular windows of standard size are the cheapest. Custom shaped windows, larger windows, and specialty windows (bay, bow, arched or picture windows) also use more material, and more rigorous installation – which drives up costs.
5. Ease of Access and Installation Conditions
Good condition windows on the ground floor are the most rapidly installed. Windows on the upper floor, tight-space windows, or rotted wood or water-damage frames are time and cost-adders. Rot repair will raise your quote by $200- $500 per window.
6. Removal and Disposal of Old Windows
Old window removal and disposal are also in the quote of most reputable installers. Whether it is listed as an option, inquire in advance, it usually is charged at an additional $50-100 each window.
Cost to Replace All Windows in a Toronto House
What would it cost to have all the windows replaced in the average Toronto house? An estimate using typical house types is as follows:
| Home Type | Typical Window Count | Estimated Total Cost |
|---|---|---|
| Condo or apartment | 4 – 6 windows | $2,000 – $6,000 |
| Semi-detached (2-storey) | 8 – 12 windows | $5,000 – $12,000 |
| Detached house (2-storey) | 12 – 18 windows | $7,500 – $18,000 |
| Large custom home | 20+ windows | $15,000 – $35,000+ |
This is the estimation of average-vinyl or fibre-glass windows with two-panes. Add 20-30% triple pane, or 40-60% premium fibreglass or wood frame.
How Much Can You Save With Ontario Window Rebates?
Good news: Ontario residential homeowners have a chance to subsidize part of the costs in various rebates schemes.
Home Renovation Savings Program (HRSP): Ontario government is now providing you with $100 each to install rough opening of windows or doors that are eligible (ENERGY STAR certified products) when you install them. With 12 windows in a house, you have $ 1,200 back in your pocket.
Enbridge Gas Rebates: Enbridge offers additional rebates on qualifying energy-efficient windows, in case your home is heated using natural gas. Enquire with your installer on whether you can purchase it or not.
Always make certain that your window company verifies your eligibility to run a current rebate program – programs and amounts vary. Milano Windows & Doors can assist you in determining what programs are applicable in your project.
Is It Worth Replacing All Windows at Once?
In most cases, yes. Installing all your windows in one project is by far cheaper per-window than doing it in phases, and guarantees your home performs, looks, and is under warranty in the same manner.
When budget is an issue, give first priority to the drafty, fogged between-panes or north facing windows (where the most heat is lost in Toronto winters).
How to Get an Accurate Quote in Toronto
The difference between window quotes among companies differs greatly not necessarily due to the difference in quality but rather due to what is offered. The quotes must specify: when using comparisons of quotes:
- Frame material and brand
- Glazing type (double or triple pane)
- Inclusion of old windows removal and disposal
- Installation warranty (labour) or product warranty (glass and frame)
- Whether the quote includes capping/trim work round the frame
A low quote that excludes these items can end up costing more than a complete quote from a reputable installer.
Why Toronto Window Prices Have Risen Since 2023
When you had windows replaced a few years ago, and now you are getting quotes that are higher than you believe, it is not an illusion on your part. Toronto window prices have been increasing due to a number of reasons:
- During and after the pandemic supply chain disruptions, there was a sharp increase in material costs (vinyl resin, glass, hardware)
- Prices of labour in Ontario skilled trades have gone up
- New building codes have made energy-efficient glazing requirements stricter
- Performance of Canadian dollar against US dollar influences imported components
As the cost of base prices increase, window replacement continues to provide one of the best returns on investment to Toronto homeowners – less heating bills, less drafts, and higher re-sale value.
