Overview

We're dedicated to reinforcing the transmission system in northeastern Ontario while supporting the growing electricity demands of its communities, industries and businesses.

Hydro One is committed to supporting growth in northeastern Ontario as demand for energy in the region continues to increase. In addition to meeting growing electricity needs, this project will strengthen the connection between the northeast and the northwest and will improve the overall resiliency of the northern Ontario transmission network.

As part of our pathway towards Reconciliation, we are offering proximate First Nations impacted by the project a 50% equity stake in the transmission line component. We're committed to working together as true partners to support this project. When completed, the new double-circuit 230 kilovolt line between Mississagi Transformer Station (near Wharncliffe) and Third Line Transformer Station (in Sault Ste. Marie) will reinforce the transmission system in northeastern Ontario while supporting the growing electricity demands of this thriving region.

Project details

The North Shore Link will extend between Mississagi Transformer Station (near Wharncliffe) and Third Line Transformer Station (in Sault Ste. Marie). As part of our planning process, we are studying several route alternatives and their variations. Your feedback plays a vital role in this planning stage. View our interactive map for an in-depth look at the routes we are currently studying. We invite you to share your questions and comments, and we welcome the chance to hear about what's important to you and your community.

Our planning process

We're committed to minimizing the effects of our projects and operations on the environment. The planning of this project will follow the Class Environmental Assessment for Minor Transmission Facilities (2022) in accordance with the Ontario Environmental Assessment Act. This applies to routine transmission infrastructure projects with predictable environmental effects that can be readily managed. Once the Class Environmental Assessment process is successfully completed, construction could commence in 2027 and be completed by the end of 2029.

Rooted in engagement and consultation, the Class Environmental Assessment ensures that potential natural, economic, social and cultural effects are thoroughly considered before a project begins. Engagement with Indigenous communities, landowners, businesses, government agencies and other stakeholders is critical to help us select the preferred route that best meets the needs and interests of the region.

Frequently asked questions

How were the route alternatives identified?

Prior to the start of the Class Environmental Assessment, we conducted preliminary work to identify route alternatives. We mapped out local features and constraints (such as waterbodies, residential areas and environmentally significant areas) and looked for opportunities to parallel linear infrastructure where feasible. Based on that data, we are studying several route alternatives and their variations to determine the preferred route.

How will the preferred route be selected?

Engagement is vital to the planning process. We will meet with Indigenous communities, members of the public, businesses, government agencies and other stakeholders to better understand the region and local interests. As a part of our environmental assessment, we will also collect data, conduct environmental field surveys and perform technical assessments. Using both the feedback and data collected, each route will be evaluated and compared to ultimately select a preferred route.
