Upgrading older single-pane or failed double-pane windows and leaky exterior doors is one of the highest-impact investments an Ontario homeowner can make. In addition to eliminating drafts and lowering winter heating bills by 12% to 15%, energy retrofits can qualify you for provincial financial incentives when completed according to program rules.
However, navigating Ontario’s energy rebate landscape in 2026 can be confusing. Federal programs have shifted, utility programs have been restructured, and misleading claims from aggressive door-to-door sales companies have left many homeowners unsure of what is actually available.
Below is our definitive, fact-checked guide to the active 2026 Ontario window and door rebate programs, the critical bundling rules you need to know, and how to successfully claim your incentives.
1. The Active 2026 Program: Home Renovation Savings (HRS)
The primary active provincial rebate stream for residential window and door upgrades in 2026 is the Home Renovation Savings Program (HRS), delivered collaboratively by Enbridge Gas and the Independent Electricity System Operator (Save on Energy).
Incentive Amounts Under HRS
- Replacement Windows: $100 per rough opening replaced with certified Energy Star Most Efficient models.
- Exterior Doors: $100 per rough opening for high-efficiency insulated entry door or patio sliding door systems.
- Whole-Home Caps: Homeowners can combine window and door incentives up to program limits when completing multi-measure retrofits.
Example Calculation: Replacing 10 older builder-grade windows and 2 exterior entry doors in a detached home yields $1,200 in direct utility rebate cheques ($100 × 12 openings), in addition to ongoing annual gas and hydro bill savings.
2. The Critical Rule: Two-Measure Bundling Requirement
The single most important policy requirement that Ontario homeowners must understand is the two-measure bundling condition.
Under Enbridge Gas HRS program rules, replacement windows and doors fall under the assessment-based pathway. This means:
- Pre-Retrofit Energy Audit Required: You must complete an initial home energy evaluation with a licensed NRCan Energy Advisor before your new windows or doors are installed.
- Bundling With a 2nd Upgrade: You cannot claim the $100/opening rebate by replacing windows or doors alone. To unlock the rebate, your window/door replacement must be paired with at least one other qualifying energy efficiency upgrade in your home, such as:
- Attic Insulation: Upgrading attic insulation to R-60.
- Exterior Wall or Basement Insulation: Insulating foundation walls.
- Comprehensive Air Sealing: Professional air barrier sealing identified by blower door testing.
- Heat Pump Installation: Installing a cold-climate air-source heat pump (ccASHP) or hybrid dual-fuel heating system.
What If You Are Replacing Windows Alone?
If your planned renovation project only involves replacement windows or doors without attic insulation or heating equipment, there is currently no active provincial utility rebate to claim.
At Comfort Windows & Doors, we believe in complete honesty. Unlike competitors who make deceptive rebate promises to close sales, we will tell you the exact policy rules upfront. When doing windows alone, you still benefit from our factory-direct Canadian pricing, precision Window Wise™ installation, and lifetime heating bill reductions.
3. Technical Requirements: What Windows & Doors Qualify?
To ensure your windows and doors pass the post-retrofit audit inspection, they must meet strict Natural Resources Canada (NRCan) building science criteria:
Window Performance Criteria
- Must be certified for Energy Star Zone 2 (Ontario climate zone).
- Must achieve a U-Factor ≤ 1.22 W/m²·K (metric) or an Energy Rating (ER) ≥ 34.
- Must feature dual-pane or triple-pane sealed glass with Low-E coatings, argon gas fill, and non-metallic warm-edge spacers.
Exterior Door Performance Criteria
- Insulated high-density polyurethane foam core with fiberglass or galvanized steel slabs.
- Must feature magnetic or dual-bulb compression weatherstripping and an anodized aluminum thermal break sill.
- Any decorative glass inserts must feature insulated Low-E tempered glass.

5. Step-by-Step: How to Successfully Claim Your Rebate
Follow this 4-step roadmap to ensure your project qualifies without administrative delays:
Step 1: Schedule Your Pre-Retrofit EnerGuide Home Assessment
Contact a licensed Registered Energy Advisor (REA) through a certified service organization. The advisor performs a blower door air leakage test, inspects existing window frames, measures attic insulation, and generates an official EnerGuide Home Energy Assessment Report with your custom Energy Efficiency Roadmap.
Step 2: Select Your Certified Windows & Doors
Work with the specialists at Comfort Windows & Doors to measure rough openings and select certified models. We verify that all specified window styles (casement, awning, hung, slider) and door configurations meet or exceed Energy Star Zone 2 requirements.
Step 3: Precision Window Wise™ Certified Installation
Our in-house master installers complete the installation using continuous low-expansion insulating foam, acoustic caulking, and custom exterior aluminum capping.
Important Paperwork Notice: Keep all NRCan Energy Star efficiency stickers attached to the glass until your Energy Advisor completes the follow-up inspection! We provide certified manufacturer labels, NFRC performance certificates, and itemized compliance receipts.
Step 4: Complete Post-Retrofit Audit & Receive Cheque
After your windows, doors, and second upgrade measure (e.g., attic insulation) are fully installed, your Energy Advisor performs the final audit to verify improvements. They submit the documentation directly to the Enbridge portal, and your rebate cheque is mailed directly to your home.
Municipal Financing: City of Toronto HELP Program
If your property is located within the City of Toronto, you may also qualify for the Home Energy Loan Program (HELP):
- Offers up to $125,000 in low-interest financing for comprehensive residential energy retrofits.
- Repayment is conveniently tied to your regular municipal property tax bill.
- Terms extend up to 20 years and the loan is transferable if you sell your property.
