Hydro One has been selected to develop a critical transmission line in the northeast of the Canadian province of Ontario in partnership with First Nations.

The Ontario Energy Board has been directed by the Minister of Energy and Electrification to amend Hydro One’s transmission licence, enabling them to construct the project.

The line will support the increasing electricity demand in the region.

The project will address the growing need for electricity in northern Ontario, driven by the electrification of communities, businesses and industries.

It will support population growth and economic development, including advanced manufacturing and mining for critical minerals.

Hydro One president and CEO David Lebeter stated: “Electricity is the backbone of our economy and Hydro One provides the power needed to support daily life and attract new growth and investment in communities across the province.

“The designation acknowledges how Hydro One has prioritised Indigenous partnerships and reconciliation. We thank the government for their support and will continue to work in collaboration with partners to develop and build this critical line.” 

Hydro One will collaborate with First Nations, offering them a chance to invest in an equity stake in the transmission line through a 50-50 equity partnership model.

The project involves constructing a new 260km, 500kV transmission line, initially energised at 230kV, connecting the Wawa transformer station and the Porcupine transformer station in Timmins.

The transmission line will be operational by the end of 2030.

Missanabie Cree First Nation chief Gauthier said: “As we move forward with the designation of Hydro One and partners to build the transmission line between Wawa and Timmins, it’s not just about infrastructure – it’s about strengthening our communities, connecting people and ensuring a sustainable, reliable future for the north. This project will power progress and create lasting opportunities for all our people.”

The Wabun chiefs and Wabun tribal council stated: “This project not only provides value to our communities as owners of infrastructure, but increases the transmission capacity in the grid system that is desperately needed. We look forward to working with the ministry and other stakeholders as we plan and build the line over the coming years.”  

The project aligns with the Independent Electricity System Operator’s forecast of a 75% increase in electricity demand across Ontario by 2050.

The line will enhance Ontario’s clean energy advantage, making the province more attractive for living and investment.
