Window and Door Replacement Cost Ontario 2026: Prices and Rebates
A full breakdown of what windows and doors cost in Ontario by material, style, and glass type. Plus how to claim $100 per opening in provincial rebates through the Home Renovation Savings Program.
Key Takeaways
- A full-house window replacement (15 to 20 windows) costs $9,000 to $20,000 for vinyl and $13,500 to $30,000 for fibreglass.[2]
- The HRS program pays $100 per window or door rough opening, up to $5,000 total. A 12-window, 2-door project qualifies for roughly $1,450.[1]
- Triple pane windows cost 30 to 40% more than double pane but deliver 10 to 15% more heating savings, making them the stronger long-term choice for Ontario winters.[3]
- New Energy Star windows and doors can reduce heating and cooling costs by 20 to 30%.[9]
- Toronto HELP financing starts at 3.08% over 5 years and can be combined with HRS rebates.[4]
Window Costs by Material
Material choice is the single biggest factor in what you will pay. The table below shows per-window installed costs for the three main frame materials used in Ontario.[2]
| Frame Material | Cost per Window (Installed) | Full House (15-20 Windows) | Maintenance |
|---|---|---|---|
| Vinyl (double-hung) | $500 - $1,000 | $9,000 - $20,000 | None (wipe clean) |
| Fibreglass | $900 - $1,500 | $13,500 - $30,000 | Minimal |
| Wood (interior) / clad (exterior) | $1,200 - $2,500+ | $18,000 - $50,000+ | Regular staining/painting |
Vinyl is the most popular option in Ontario for good reason: it insulates well, never needs painting, and costs roughly half as much as fibreglass. Fibreglass is worth the premium if longevity and seal integrity matter most to you. Fibreglass expands at nearly the same rate as glass, which reduces seal failure over time.[3]
Wood windows are a premium product. They look exceptional but require regular exterior maintenance. In Ontario's freeze-thaw climate, exposed wood frames take a beating unless protected by an aluminum or fibreglass cladding on the exterior.
Triple Pane vs. Double Pane: Which Makes Sense in Ontario?
This is one of the most common questions Ontario homeowners face during a window replacement project. The short answer: for most homes in southern Ontario and anywhere north, triple pane is the better investment.[3]
| Specification | Double Pane | Triple Pane |
|---|---|---|
| Cost per window | $600 - $1,000 | $800 - $1,400 |
| Price premium | Baseline | 30 to 40% more |
| Heating savings vs. old windows | Good | 10 to 15% more than double pane |
| Condensation resistance | Moderate | Excellent |
| Sound reduction | Moderate | Significantly better |
| Best for | Mild climates, tight budgets | Ontario (zones 6 and 7) |
Triple pane windows have three layers of glass with two insulating gas fills (typically argon), compared to double pane's single gas fill. That extra layer makes a real difference in Ontario winters: less condensation on interior glass, better comfort near windows, and lower heating bills.[9]
The main trade-off is upfront cost. For a 15-window project, triple pane adds roughly $3,000 to $6,000 to the total. If you plan to stay in the home for 10+ years, the ongoing energy savings and improved comfort make triple pane the stronger choice. If resale is within 3 to 5 years, double pane delivers a better return on investment.
Specialty Window Costs
Bay and bow windows are popular in Ontario living rooms and dining rooms. They cost significantly more than standard units due to the structural framing and larger glass area involved.[2]
| Window Type | Installed Cost | Notes |
|---|---|---|
| Bay window | $3,000 - $6,000 | 3 panels, may need structural support |
| Bow window | $3,500 - $7,000 | 4 to 6 panels, curved frame |
Both bay and bow windows typically require structural headers and may involve exterior brick or siding modifications, which accounts for the higher labour costs. Get quotes that include all framing and finishing work, not just the window unit itself.
What Drives Installation Costs
Installation labour runs $150 to $400 per window and varies based on several factors specific to Ontario homes.[2]
- Brick vs. siding: Brick openings take longer to prep and finish. Expect to pay toward the higher end of the range for brick exteriors.
- Structural modifications: If the new window is a different size than the existing opening, framing changes add $200 to $500 per window.
- Floor level: Second and third floor installations require scaffolding, which adds to the project total.
- Permit requirements: Ontario municipalities generally do not require permits for same-size window replacements. Changing the opening size or adding new windows typically requires a building permit.
A reputable installer will include removal and disposal of old windows, interior and exterior trim finishing, and insulation and caulking around the new frame. Ask what is included before comparing quotes.
Door Replacement Costs
Exterior doors affect both energy efficiency and security. The table below covers the most common door types installed in Ontario homes.[5]
| Door Type | Installed Cost | Key Features |
|---|---|---|
| Front entry (steel) | $1,500 - $3,000 | Most affordable, best security, can dent |
| Front entry (fibreglass) | $2,000 - $5,000 | Best insulation, weather resistant, no dents |
| Front entry (wood) | $3,000 - $8,000 | Premium look, requires maintenance |
| Patio sliding (6 ft) | $1,500 - $3,000 | Space-saving, common in GTA condos/towns |
| Multi-panel sliding | $3,000 - $8,000 | 8 to 16 ft openings, modern look |
| French door (pair) | $2,500 - $5,000 | Classic style, needs swing clearance |
For front entry doors, fibreglass has become the most popular choice in Ontario. It insulates better than steel, will not dent or rust, and can be finished to look like wood grain. Steel remains the most affordable option and offers the best security ratings.[6]
Patio and sliding doors are a significant source of heat loss in many Ontario homes. If your sliding door is more than 15 years old, the seals and rollers have likely degraded. A replacement with a modern Energy Star unit can noticeably reduce drafts and improve the comfort of adjacent rooms.
Ontario Window and Door Rebates (HRS Program)
The Home Renovation Savings (HRS) program through SaveOnEnergy is the primary rebate for windows and doors in Ontario.[1]
How the HRS Rebate Works
- $100 per window or door rough opening, regardless of window size.[1]
- Maximum of $5,000 for windows and doors combined.[1]
- Products must be Energy Star certified.[9]
- No energy audit required for this stream. Use our rebate checker to see what you qualify for.
Example Rebate Calculation
| Item | Quantity | Rebate per Opening | Total Rebate |
|---|---|---|---|
| Windows | 12 | $100 | $1,200 |
| Front entry door | 1 | $100 | $100 |
| Patio sliding door | 1 | $100 + $50 (sidelight) | $150 |
| Total estimated rebate | $1,450 | ||
Stacking with Other Rebates
The HRS window and door rebate can be stacked with other programs when you bundle multiple upgrades.[8]
- Enbridge Home Efficiency Rebate Plus: additional incentives when you combine windows with insulation, heating, or air sealing upgrades.[8]
- Multi-measure HRS stream: up to $7,700 total across all upgrades (requires energy audit).[1]
For a full breakdown of every available rebate and how to stack them, see our Ontario Home Energy Rebates 2026 guide.
Energy Savings: What to Expect
Windows and doors account for a significant portion of heat loss in Ontario homes. Replacing aging units with modern Energy Star products delivers measurable savings.[9]
| Metric | Value |
|---|---|
| Heating/cooling reduction with new windows | 20 to 30% |
| Annual savings (average Ontario home) | $500 - $1,050 |
| Additional savings from triple vs. double pane | 10 to 15% |
| HRS rebate (12 windows + 2 doors) | ~$1,450 |
| Payback period (vinyl, 15 windows) | 8 to 15 years |
Window replacement has a longer payback period than insulation upgrades. However, the benefits extend well beyond energy savings: reduced street noise, less condensation, improved comfort near windows in winter, and better curb appeal all factor into the value equation.
If you are planning a window project alongside insulation, that combination often delivers the best overall energy improvement. See our Attic Insulation Cost Ontario guide for details on that side of the equation.
Financing Options
Window and door replacements are a significant upfront investment. Several financing paths are available to Ontario homeowners.[4]
Toronto HELP Loan
The City of Toronto's Home Energy Loan Program (HELP) offers low-interest financing for energy-efficient home upgrades, including windows and doors.
- 5-year term: 3.08% interest rate.
- 10-year term: 3.87% interest rate.
- 20-year term: 4.67% interest rate.
- Loan is repaid through your property tax bill.
- Can be combined with HRS rebates, meaning you reduce the principal and borrow at a low rate.
Contractor Financing
Many Ontario window companies offer in-house financing or partnerships with lenders. Read the terms carefully. Interest rates on dealer financing are often 6 to 12%, significantly higher than the HELP program. A home equity line of credit (HELOC) is another option, typically at prime + 0.5 to 1%.
Getting Accurate Quotes
Window and door pricing varies significantly between contractors. A few practical steps to get reliable numbers:
- Get at least three in-home quotes. Online estimates are too vague for windows because every opening is different. A reputable company will measure every window and provide a detailed, itemized quote.
- Compare apples to apples. Make sure each quote specifies the same glass type (double vs. triple pane), frame material, and Energy Star rating. Ask whether installation includes interior and exterior trim, insulation, and old window disposal.
- Check the warranty. Look for a minimum 20 year warranty on glass seal failure and a lifetime warranty on vinyl frames. Fibreglass frames should carry at least a 25-year structural warranty.
- Verify the installer. Ask for proof of WSIB coverage and liability insurance. Check reviews on Google and HomeStars. A low quote from an uninsured installer is not a bargain.
- Time your project. Fall and winter are typically the slowest seasons for window installers. You may be able to negotiate 5 to 10% off by booking during the off-season.

Frequently Asked Questions
How much does it cost to replace windows in Ontario?
For a typical Ontario home with 15 to 20 windows, a full replacement costs $9,000 to $20,000 for vinyl and $13,500 to $30,000 for fibreglass. Per window, vinyl double-hung units run $500 to $1,000 installed, while fibreglass ranges from $900 to $1,500. Installation labour adds $150 to $400 per window depending on size and whether the opening is in brick or siding.
Are triple pane windows worth it in Ontario?
In most of Ontario, yes. Triple pane windows cost $800 to $1,400 per unit compared to $600 to $1,000 for double pane, a premium of roughly 30 to 40%. However, they deliver 10 to 15% more heating savings and significantly reduce condensation in Ontario winters. For homes in climate zones 6 and 7 (GTA and north), the energy savings typically recoup the extra cost within 5 to 8 years.
What rebates are available for windows and doors in Ontario?
The Home Renovation Savings Program (HRS) through SaveOnEnergy offers $100 per window or door rough opening, up to $5,000 total. For example, replacing 12 windows and 2 doors qualifies for approximately $1,450 in rebates. Windows and doors must be Energy Star certified. You can stack HRS rebates with Enbridge gas incentives if you bundle with other efficiency upgrades.
How much does a front door replacement cost in Ontario?
A steel entry door costs $1,500 to $3,000 installed. Fibreglass entry doors run $2,000 to $5,000 and offer better insulation and weather resistance. Solid wood entry doors range from $3,000 to $8,000 and require more maintenance in Ontario's freeze-thaw climate. All three qualify for the $100 per opening HRS rebate if Energy Star certified.
How much can new windows save on energy bills?
Replacing single pane or aging double pane windows with modern Energy Star units can reduce heating and cooling costs by 20 to 30%. For an average Ontario household spending $2,500 to $3,500 per year on heating and cooling, that translates to $500 to $1,050 in annual savings. Triple pane windows push those savings an additional 10 to 15% compared to double pane.
What is the best window material for Ontario?
Vinyl is the most popular choice in Ontario, offering the best balance of price, insulation, and low maintenance. It does not rot, peel, or need repainting. Fibreglass is stronger and expands at nearly the same rate as glass, which reduces seal failure over time. Wood windows offer a premium look but require regular exterior maintenance and are the most expensive option.
Can I finance window and door replacements in Ontario?
Yes. The City of Toronto HELP loan program offers financing at 3.08% for a 5-year term up to 4.67% for a 20-year term. These loans can be combined with HRS rebates. Many window companies also offer in-house financing, though the interest rates are typically higher. Getting quotes from multiple contractors and comparing financing terms is important.
