All renovations must be completed by contractors who have been screened by the Green Ontario Fund.

Why is it Important to Go Green?

The Green Ontario Fund and Rebates program is important for a number of reasons. We all need to do our part to reduce our carbon footprint, which is a definite positive step in the right direction. But there are also many monetary benefits that come with environmentally responsible decisions for your home. By upgrading your insulation, you can save an additional 15% on your cooling and heating costs. These energy efficient upgrades will result in reduced heating and cooling expenses, which also provides you with immediate savings on your energy bill. Furthermore, upgrades like new windows and improved insulation increase your home’s resale value if you plan on selling now or in the future.
