Chatham-Kent to Lakeshore Project logo with tagline: Growing locally to power tomorrow
As demand for electricity in Southwestern Ontario is anticipated to grow significantly over the next several years, Hydro One is building a new transmission line between Chatham-Kent to Lakeshore.

A safe and reliable power supply is essential to ensure southwestern Ontario can continue to grow now and into the future. That’s why Hydro One is proposing to construct a new double-circuit 230 kilovolt transmission line from our Chatham Switching Station located in the Municipality of Chatham-Kent to the future Lakeshore Switching Station, which will be located in the Municipality of Lakeshore. This new transmission line will help accommodate future electricity growth, improve reliability for homes and businesses and support local industries in the region at a time when it is needed most.

The proposed project requires the completion of a Class Environmental Assessment (Class EA), as well as Ontario Energy Board (OEB) approval (Leave-to-Construct application under Section 92 of the OEB Act).
 

Class Environmental Assessment

The Chatham to Lakeshore Line is subject to the Class Environmental Assessment for Minor Transmission Facilities (2022) , in accordance with the Ontario Environmental Assessment Act. The Class EA is a streamlined planning process ensuring that applicable projects are planned and carried out in a manner that is efficient and environmentally acceptable.

Since January 2020, Hydro One has been conducting a Class EA to build the new Chatham to Lakeshore Line. Through the Class EA process, we have assessed three route alternatives and associated variations by collecting environmental and technical information, as well as input from agencies, Anishnawbek and Haudenosaunee communities, community members, elected officials, interest groups and businesses. Based on the information gathered and feedback received, Route Alternative 2A was selected as the preferred route for the new transmission line, as shown on the maps below.

The draft ESR outlines the Class Environmental Assessment (EA) process undertaken for the proposed project, including alternatives identified, environmental information collected, consultation undertaken, the route evaluation and selection process, and environmental effects and mitigation measures planned. The document was available for review and comment for 60 days, from June 11, 2021 until August 10, 2021.
