If you’re a homeowner in the Greater Toronto Area, 2026 is shaping up to be one of the best years in recent memory to upgrade your windows. Between provincial programs, federal incentives, and utility rebates, qualifying homeowners can now access over $7,800 in combined financial support — and that’s before factoring in the long-term energy savings.
At Fortress Windows & Doors, we’ve helped hundreds of GTA homeowners navigate these programs. Here’s what you need to know heading into 2026.
Why 2026 Is a Big Year for Window Rebates in Ontario
Several factors are converging this year to make window upgrades more financially accessible than ever:
- The federal government has expanded the Canada Greener Homes Loan Program
- Ontario’s Home Renovation Savings Program (HRSP) has increased its rebate caps
- Enbridge and Toronto Hydro have renewed their energy efficiency incentives
- New CMHC financing options are making it easier to fund upgrades upfront
Combined, these programs create a compelling financial case for replacing older, inefficient windows — especially in homes built before 2000.
The Major 2026 Window Rebate Programs in Ontario
1. Ontario Home Renovation Savings Program (HRSP)
Who it’s for: Ontario homeowners replacing windows and doors with energy-efficient alternatives
Rebate amount: Up to $5,000 for windows and doors combined
Key requirements:
- Windows must meet ENERGY STAR® Most Efficient criteria
- A pre- and post-upgrade home energy assessment is required
- Work must be performed by a registered contractor
How to apply: Through the Enbridge Gas HRSP portal (for gas-heated homes) or the equivalent program through your local electricity distributor
2. Canada Greener Homes Affordability Program (CGHAP)
Who it’s for: Low- to median-income Canadian homeowners
Rebate amount: Up to $5,000 for eligible upgrades, including windows
Key requirements:
- Household income must be at or below the program threshold (varies by province)
- Must be a primary residence
- EnerGuide evaluation required
Note: This program is income-tested, but the rebates are more generous for those who qualify
3. Home Energy Loan Program (HELP) — City of Toronto
Who it’s for: Toronto homeowners specifically
What it offers: Low-interest financing (not a grant) of up to $75,000 for energy upgrades
Key benefit: Repaid through your property tax bill — no large upfront cost
This is particularly useful if you’re combining window replacement with other energy retrofits like insulation or HVAC upgrades.
4. CMHC Mortgage Insurance Refund
Who it’s for: Homeowners with CMHC-insured mortgages who make energy-efficient upgrades
What it offers: Up to 25% refund on CMHC mortgage insurance premiums
Note: Must be used in conjunction with an EnerGuide home evaluation

What Windows Qualify?
Not all window replacements are created equal in the eyes of these programs. To qualify for most rebates, your new windows typically need to:
- Meet ENERGY STAR® Most Efficient designation
- Have a U-factor of 1.22 W/m²·K or lower
- Feature low-emissivity (low-e) glass coatings
- Include argon or krypton gas fill between panes
- Have thermally broken frames (available in vinyl, fibreglass, or aluminum)
All of Fortress Windows & Doors’ product lines meet or exceed these standards. When you purchase through us, we’ll provide the documentation needed to support your rebate application.
Step-by-Step: How to Access Your Rebates
- Book a home energy assessment — Required by most programs, this EnerGuide evaluation establishes your home’s baseline energy performance. Cost: $400–$600, but partially rebated by some programs.
- Get a quote from a registered contractor — Your installer must be registered under the relevant program. Fortress Windows & Doors is registered under Ontario’s HRSP.
- Confirm product eligibility — We’ll verify which windows qualify under the program and document the specs for your application.
- Complete the installation — All work must be completed before your rebate application is submitted.
- Get your post-upgrade assessment — A second EnerGuide evaluation is required to confirm the improvement in energy performance.
- Submit your application — We’ll walk you through the paperwork and help you gather the required documentation (invoices, evaluation reports, product specs).
- Receive your rebate — Processing times vary by program: HRSP typically takes 6–10 weeks, while federal programs can take up to 16 weeks.
Common Mistakes That Cost Homeowners Their Rebates
Over the years, we’ve seen homeowners lose out on thousands of dollars in rebates due to avoidable mistakes. Here are the most common:
- Not booking the pre-upgrade assessment before work begins (retroactive assessments are not accepted)
- Choosing a non-registered contractor — always confirm your installer is registered under the specific program
- Purchasing windows that don’t meet the efficiency threshold — “energy efficient” in marketing materials doesn’t always mean ENERGY STAR® Most Efficient
- Missing application deadlines — most programs have a 90-day post-installation window to submit
- Incomplete documentation — missing invoices, product spec sheets, or evaluation reports will delay or disqualify your application
Frequently Asked Questions
Can I combine multiple rebate programs?
Yes — in many cases, provincial and federal programs can be stacked, as long as you meet the eligibility requirements for each. For example, a qualifying homeowner could receive both the HRSP rebate and utility rebates for the same project.
Do I need to replace all my windows to qualify?
No. Most programs allow partial replacements, though replacing more windows generally increases your rebate amount and results in a larger improvement in your EnerGuide rating.
Does this apply to condos or rental properties?
Most programs are designed for detached, semi-detached, or row houses that are owner-occupied primary residences. Condo owners and landlords have fewer options, though some utility programs do extend to multi-unit buildings.
What’s the best window type for maximum rebates?
Triple-pane windows with low-e coatings, argon fill, and thermally broken frames consistently achieve the highest EnerGuide improvement scores — which translates to larger rebates and greater long-term savings. We recommend discussing your home’s specific needs with our team before deciding.
