Leaside to Main Infrastructure Refurbishment ProjectCome out to learn about how Hydro One is planning to strengthen the electricity transmission system in your area.

Ensuring a safe and reliable supply of power for homes and businesses across Ontario is Hydro One’s top priority. An important step toward sustaining this commitment involves maintaining and renewing our infrastructure.

We are undertaking a Class Environmental Assessment to refurbish existing infrastructure located in the eastern part of downtown Toronto. This infrastructure is a critical component of Ontario’s electricity grid and the supply of power to Toronto Hydro.

Hydro One has identified two sections of existing underground transmission cable which are nearing their end of life and require replacement. These sections, shown on the reverse map, are located between:

1. Leaside Transformer Station (TS) and Todmorden Junction (JCT)2. Lumsden JCT and Main TS

The replacement of underground cables is subject to the provincial Environmental Assessment Act and is being planned in accordance with the Class Environmental Assessment for Minor Transmission Facilities.

In conjunction with this work, Hydro One will take the opportunity to replace and upgrade the overhead wire (skywire),used to protect our equipment from lightning, between Todmorden JCT and Lumsden JCT.

Public input and feedback is an important part of our planning process, and we want to hear from you. Please join us at one of our upcoming Public Information Centres to learn more about the proposed work in your community:
