East-West Tie Transmission Line Project

The Project is a 450 kilometer, double-circuit, 230-kilovolt transmission line from the Wawa Transformer Station (TS) to the Lakehead TS in the Municipality of Shuniah, near Thunder Bay, Ontario, with a connection approximately mid-way at the Marathon TS.

Construction of the project began in September 2019 and was completed on March 31, 2022.
