Islington Transformer Station & Line Project

Hydro One is committed to energizing life for communities, people, and businesses across Ontario. As industry and businesses grow in the City of Toronto, so does the need for safe, clean and reliable power. In fall 2022, Hydro One initiated a Class Environmental Assessment (Class EA) to connect a new data facility, planned at 48 Lowe’s Place in Etobicoke, to the electricity grid.

Current project phase

Construction

We're here to help you

Project components include:

  • Building a new 230 kilovolt (kV) transformer station (TS) located on the facility’s property
  • Installing two new junction stations – which will help transition power from an overhead transmission line to an underground cable – within the existing Hydro One transmission line corridor, east of Islington Avenue and Rexdale Boulevard
  • Installing two new underground 230 kV transmission line cables between the new junctions and the new TS

On-going construction

Last updated February 5, 2025

As a part of the project we are installing two new underground 230 kV transmission line cables. This project will include closing roads and lanes as the crew will need to excavate and trench along the route path for initial equipment installation. The timeframes below are based on our current knowledge of the project and site working conditions.
