Parry Sound/Muskoka - Regional Plan

​The Parry Sound/Muskoka area constitutes a sub-region of the South Georgian Bay/Muskoka region established through the Ontario Energy Board's regional planning process.

Current status: An Integrated Regional Resource Plan (IRRP) is underway for this sub-region.


How to get involved

A Local Advisory Committee has been established to help provide input into the development of the plan, and discuss ways to best meet electricity needs while considering local priorities.     

Subscribe to receive updates on the plan, notices for Local Advisory Committee meetings, and to learn about opportunities for municipalities, First Nation communities, community groups, stakeholders and the general public to provide input for the Parry Sound/Muskoka area.


IRRP Working Group

A Working Group consisting of the local distribution companies in the region, the local transmitter and the IESO will use the regional planning process to identify and meet local electricity needs. The Working Group consists of staff from Lakeland Power, Midland PUC, Newmarket-Tay Power, Orillia Power, PowerStream, Veridian Connections, Hydro One Distribution, Hydro One Transmission and the IESO.


Area overview

The Parry Sound/Muskoka sub-region roughly encompasses the Districts of Muskoka and Parry Sound, and the northern part of Simcoe County.  A full listing of the municipalities in the regional planning area can be found in the Terms of Reference document. This sub-region also includes eight First Nation communities:  Beausoleil, Chippewas of Rama, Henvey Inlet, Magnetawan, Moose Deer Point, Shawanaga, Wahta Mohawks and Wasauksing.

The electricity demand in this sub-region is primarily driven by residential and commercial uses, especially electric heating during the winter season.  This region also supports a mix of economic activities including tourism, retail, health care and manufacturing industries. Electricity demand in this area typically peaks during the winter months, with historical peak demand ranging from around 470- 530 MW

A modest increase in electricity demand is forecasted over the next 20-year for the area.  While slower growth is expected in the region's manufacturing sector, growing Aboriginal communities, developments in the tourism and retail sector, and potential local economic development such as the Parry Sound Airport Development and Rama Road Corridor Economic Employment District, will contribute to the electricity demand requirements for the region.

Given the large geographical area, many communities in the Parry Sound/Muskoka sub-region are supplied by long transmission and distribution networks and rely on single supply sources. Regional planning will examine the reliability performances of the transmission and distribution infrastructure and where appropriate, examine options to mitigate the potential impact of power outages to communities and businesses in the area.   Given the forecasted demand growth in this sub-region, there may be opportunities for communities to manage growth through the development of community-based solutions, including energy efficiency measures, distributed generation, demand response programs and other innovative technologies.
