Ontario Connecting Ring of Fire with New Transmission Line

January 28, 2026

the Ontario government is declaring the Greenstone Transmission Line a priority project and designating Hydro One to develop and construct it.

The 230-kilometre transmission line will run from Nipigon Bay to near Aroland First Nation and represents a major step forward to power northern Ontario and unlock the vast economic potential of Ring of Fire. The project will create more than 7,000 jobs and is part of the government’s broader plan to protect Ontario by driving economic growth in the North, supporting mining sector development and reshoring Ontario’s domestic supply chains. 

This nation-building investment strengthens Ontario’s energy security, advances economic reconciliation through meaningful Indigenous partnership, and ensures northern communities have the infrastructure they need to grow and prosper for generations.
