Hydro One Limited has been designated by the Ontario government to develop and construct a new priority 500-kilovolt transmission line between Sudbury and the Barrie area. The single-circuit line will span about 300 kilometres from the Hanmer Transformer Station to the Essa Transformer Station and is expected to be in service in 2032.
The designation also directs Hydro One to complete development work for a second new 500-kV line on the same corridor to support future growth and new generation in northern Ontario. Through Hydro One’s First Nation Equity Partnership Model, proximate First Nations can invest in a 50 per cent equity stake in the transmission line component, sharing in ownership and helping guide planning, development and construction. The project is positioned as a key part of strengthening Ontario’s north-south electricity grid and enabling long-term economic and resource development.
