Canada Greener Homes Initiative

In May 2021, the government of Canada introduced the Canada Greener Homes initiative to assist homeowners with making energy-efficient upgrades to their homes among other incentives. Some of these upgrades include but are not limited to the addition of solar panels. As part of the grant application process, it may be necessary to provide a letter of approval or permission for the interconnection of your grid-connected solar system. Should this be required, you may provide the offer to connect letter issued by Hydro One for < 10kW projects or a copy of your Connection Impact Assessment (CIA) for > 10kW projects. For more information about the grant, you can access the Government of Canada website: Eligible retrofits and grant amounts (nrcan.gc.ca).

Important News Regarding Amendments to the Planning Act for Renewable Energy Generation Facilities

The siting restrictions in O. Reg. 274/18 which were administered by electricity distributors such as Hydro One have been replaced by amendments to the Planning Act (Ontario) that puts siting and planning requirements for renewable energy generation facilities under municipal oversight.

If we have provided you with a Connection Impact Assessment ("CIA") and a Connection Cost Agreement ("CCA"), it does not mean that you are permitted to build your Generation project in the municipality where your Generation project is located. As such, we recommend, if you have not done so already, that you immediately discuss municipal permitting and approvals requirements with the planning department in the municipality where your Generation project is sited before you proceed.
