Of long-term community benefits

Reinforcing the transmission system in Ontario.

Long-term electricity demand in Ontario is increasing. Waasmoowin, in partnership with Hydro One, is committed to meeting this challenge and expanding Ontario's electricity network.

Hydro One is investing in the North Shore Link (NSL) and the Northeast Power Line (NEPL). Once built, these transmission lines will strengthen the capacity between northeast and northwest Ontario, and support the growing electricity demands of its communities, industries and businesses.

These projects will deliver reliable power to Ontario and strengthen the region's energy network for a more resilient future.
