Hydro One's Strategic Move for Electricity Enhancement

Introduction
On September 11, 2026, Hydro One Networks Inc. along with Hydro One Sault Ste. Marie LP (HOSSM) formally filed an application with the Ontario Energy Board (OEB) to seek permission for the construction of the North Shore Link. This pivotal project aims to bolster the electrical infrastructure in northeastern Ontario, addressing the growing demands for reliable electricity.

Project Overview
The North Shore Link involves constructing a new 230-kilovolt transmission line that will link the Mississagi Transformer Station, located near Wharncliffe, to HOSSM's Third Line Transformer Station in Sault Ste. Marie. This initiative is expected to enhance connectivity between Ontario's northeast and northwest, ultimately strengthening the overall transmission system.

Alongside this construction, Hydro One plans to upgrade the Mississagi Transformer Station and expand the Algoma Transformer Station to comply with system requirements. HOSSM will oversee all necessary upgrades at Third Line Transformer Station, reflecting a comprehensive approach to modernize and improve service delivery in the region. The total investment for this ambitious project is projected to be around $1.3 billion, with the aim for the line to become operational by 2029.

Collaborative Efforts with First Nations
A noteworthy aspect of the North Shore Link project is Hydro One's commitment to working with First Nations. Under Hydro One's First Nation Equity Partnership Model, there will be opportunities for nine potential First Nation partners to invest in a 50 percent equity stake in the transmission line section of the project. This partnership symbolizes a collaborative effort in planning, development, and construction, fostering stronger relationships with local communities.

Growing Electricity Needs
Ryan Docherty, Hydro One's Executive Vice President of Capital Portfolio Delivery, emphasized the critical need for the project. As electricity demand continues to rise in Ontario, the existing infrastructure struggles with aging components, often exacerbated by severe weather conditions. Reliable electricity is vital for everyday life and local businesses, and the imperative to strengthen the system has never been more urgent.

“The North Shore Link is integral to a series of important investments that we will pursue in conjunction with First Nations. Our shared goal is to construct a more resilient and robust electricity grid that not only supports economic growth but also meets Ontario's future electricity requirements,” Docherty stated.

Filing Details
To proceed with the construction, Hydro One is required to file a leave-to-construct application under Section 92 of the Ontario Energy Board Act, 1998. This documentation includes comprehensive information regarding the project’s routing, design, timeline, and financial implications, underscoring the regulated nature of electricity transmission infrastructure in Ontario aimed at ensuring transparency and accountability.
