$500 rebate

Get $500/window up to $5,000 in rebates for upgrading your home to select high performance windows, through the Green Ontario Fund.

Protect your home from the outside elements with rebates for select high-energy-efficiency windows for your home. A well-insulated home keeps the desired indoor temperature better while helping to reduce heating and cooling costs, hence reducing your home’s carbon footprint.

Who Can Participate

Ontario residents who live in a detached home, townhome or semi can take part in GreenON Rebates. If you rent, you must have the written permission of the landlord.

What is the GreenOn Rebate Program?

GreenON Rebates for High-Performance Windows available through Green Ontario Fund cover $500/window up to $5,000 when upgrading to select high-performance windows. Todays high-performance windows are designed to reduce energy loss, condensation, and noise, while increasing home comfort and resale value.

Note: the rebate applies for each rough opening. This means that bay or bow windows with more than one glass unit and windows with pillars qualify as one rough opening and only one rebate.
