How to Use the Canada Greener Homes Loan for Energy- Efficient Window and Door Replacements
Are you looking to reduce energy bills and increase your home’s comfort, with the bonus of boosting your homes curb appeal? It’s an ongoing question we have, and we even know what the fix is, but we never seem to have the funds for the proper window and door replacement.
The answer for homeowners in Ontario is the Canada Greener Homes Loan Program which provides a rare opportunity to finance these upgrades with a zero percent interest rate and long-term repayment flexibility over a ten-year period.

Here is everything you need to know about using the Canada Greener Homes Loan to finance your window and door project:
1. What is the Canada Greener Homes Loan?
Launched by the Government of Canada, the Canada Greener Homes Loan is designed to help homeowners make eligible energy-efficient home renovations, such as:
2. Why Replace Your Windows and Doors
Windows and doors are one of the most common sources of heat loss in Canada homes. In fact, inefficient windows and doors can account for up to 25% of total energy loss, especially during Ontario's cold winters and hot, humid summers.
ENERGY STAR® certified windows and doors meet strict energy efficiency guidelines set by NRCan- making them eligible for the loan.
3. How much can you borrow for Windows and Doors
The amount you can borrow depends on the scope of your project and the energy savings potential. Most Ontario homeowners replacing windows and doors qualify for $5,000 to $40,000 in financing under this program.
Here is what is typically covered:
Item | Minimum Performance Criteria | |
Windows | ENERGY STAR® certified for your climate zone (Zone 2 or 3 in Ontario) | |
Doors | ENERGY STAR® certified with insulated core and weatherstripping |
You can replace up to 20 windows and doors in total, depending on your evaluation report.
