Ontario Powers the Path Forward: Northfield and Juno Welcome Historic Power Infrastructure for the Ring of Fire

Executive Summary

• Ontario has designated the 230‑km Greenstone Transmission Line as a priority project, with Hydro One tasked to develop and construct it.
• The line will add up to 700 MW of capacity, is slated for completion by 2032, and is expected to create more than 7,000 jobs while keeping 93 % of costs in Canada.
• The announcement reinforces Northfield’s investment thesis in Juno Corp., the largest mineral claim holder in the Ring of Fire, and signals a major catalyst for future mining development in the region.

Key Details

• Project Scope: 230‑kilometre, single‑circuit 230 kV transmission line from Nipigon Bay to near Aroland First Nation; designed to support a future second circuit.
• Capacity & Timeline: Up to 700 MW of additional electrical capacity; targeted completion year 2032.
• Economic Impact: Anticipated creation of >7,000 jobs; 93 % of project costs to date remain in Canada.
