Hydro One Seeks $1.3B Approval for North Shore Link to Bolster Ontario Grid — Hydro One Limited

Event summary

Hydro One and Hydro One Sault Ste. Marie LP filed a joint application with the Ontario Energy Board to build the $1.3B North Shore Link, a 230-kilovolt transmission line connecting Wharncliffe to Sault Ste. Marie.
The project includes upgrades to Mississagi, Algoma, and Third Line transformer stations, with completion expected in 2029.
Nine First Nation partners may invest in a 50% equity stake in the transmission line component under Hydro One's First Nation Equity Partnership Model.
The investment aims to strengthen the connection between northeast and northwest Ontario, improving grid resiliency amid rising electricity demand and aging infrastructure.

The big picture

Hydro One's $1.3B North Shore Link project reflects the growing need for grid modernization in Ontario, where rising electricity demand and climate-related risks are straining aging infrastructure. The inclusion of First Nation partners underscores a broader trend in energy infrastructure toward collaborative governance models, potentially setting a precedent for future projects. With $3.4B invested in 2025 alone, Hydro One is positioning itself as a key player in Ontario's long-term energy strategy.
