US EditionOntario Designates Hydro One to Build the Greenstone Transmission Line
Hydro One will build a 230-km line to deliver 350–700 MW to support mining and reduce diesel reliance in First Nations, with completion targeted for 2032.
- On Jan. 28, 2026, the Honourable Stephen Lecce directed the Ontario Energy Board to designate Hydro One Networks Inc. to develop and construct the Greenstone Transmission Line as a priority project in Toronto.
- Aiming to spur mining and local growth, officials noted the Greenstone Transmission Line will link northern communities to the Ring of Fire region, reduce diesel reliance for Northern and proximate First Nations, and support Indigenous community growth as Ontario projects $22 billion over 30 years.
- The plan specifies a single-circuit 230-kV line spanning 230 kilometres, expected in service in 2032, to unlock 350 to 700 megawatts of additional hydroelectricity, the province says.
- Under the plan, proximate First Nations can invest through Hydro One's First Nation 50-50 Equity Partnership Model and the initiative includes $70 million for Aroland plus $40-million and $62-million deals for roads and municipal support.
- Critics and some First Nations say consultation timelines and resources are insufficient, while the Ontario government admits it has not specified all priority goals nor if this will speed construction, though it reports 93 per cent of project costs to date stayed in Canada.
