Community Engagement
The IESO engages with local and regional communities to seek input to help inform planning activities. There are currently no active regional planning engagement activities for this region. See Key Resources below for the latest planning documents.
The most recent regional planning cycle for Barrie/Innisfil and Parry Sound/Muskoka sub-regions are complete with the release of an Integrated Regional Resource Plan (IRRP) and the supporting IRRP Appendices and Bulk Appendices in May 2022.
Following the completion of a Needs Assessment by Hydro One in April 2020, a Scoping Assessment Outcome Report and Terms of Reference for the South Georgian Bay/Muskoka region was completed in November 2020 that determined coordination was required at the sub-regional level to develop an Integrated Regional Resource Plan (IRRP) for each of the two sub-regions.
