The Toronto electricity planning region includes the City of Toronto as well as a small number of distribution feeders that supply customers in the City of Mississauga and City of Pickering. Indigenous communities in or near the region or that have an interest in the area are Mississaugas of the Credit, Six Nations of the Grand River, Haudenosaunee Confederacy Chiefs Council, York Region Métis Council, and the Huron Wendat of Wendake, Quebec.
The local distribution companies providing service to customers in the region include:
Elexicon Energy Inc.
Hydro One Networks Inc.
Toronto Hydro Electric System Limited
The IESO engages with local and regional communities to seek input to help inform planning activities.
A new regional electricity planning cycle has begun for the Toronto Region that will examine local growth and future electricity needs.
The IESO has developed a Scoping Assessment Outcome Report and Terms of Reference that identifies the need for a more comprehensive planning approach and development of an integrated regional resource plan (IRRP) for the Toronto region. It also includes the terms of reference that outlines the timing and details of the work to develop the electricity plan. This follows the completion of the Needs Assessment published by Hydro One in December 2022.
