Hydro One breaks ground on new St. Clair Transmission Line – ReNew Canada

September 10, 2025

Hydro One Inc., alongside First Nation partners and provincial and municipal leaders, celebrated the groundbreaking of the St. Clair Transmission Line. The $471.9 million investment is expected to support economic and community development in a rapidly growing region of the province.

“With today’s groundbreaking we’re building more than infrastructure, we’re taking another step forward to help power the future for the region and province. Each new line Hydro One builds is an opportunity for partnership with First Nations and to buy goods and services from Indigenous and Ontario suppliers. Together, we’re building a more self-reliant and secure electricity system to power growth in every corner of the province. We know taking action today will create a stronger Ontario for future generations,” said Megan Telford, Hydro One CEO.

The new 64-kilometre, double-circuit 230 kilovolt (kV) transmission line will connect the County of Lambton and Municipality of Chatham-Kent, while expanding the existing Chatham Switching Station and Lambton Transformer Station (TS) and converting the existing Wallaceburg TS to 230 kV by 2028.
