08:28 AM EST, 11/24/2025 (MT Newswires) -- Hydro One ( HRNNF ) transmission licence will be amended to allow a new transmission line to be constructed between Bowmanville and the Greater Toronto Area (GTA).

The announcement said the proposed project is a double-circuit 500-kilovolt (kV) transmission line from the Bowmanville switching station to a transformer station either at Parkway, Claireville or Cherrywood. The line is expected to be in service in the early-2030s.

The province has also issued priority designation to this line and two other projects: a reconductoring of a portion of Hydro One's ( HRNNF ) existing transmission line from the Orangeville transformer station to the Essa station, expected to be in service in 2027, and a new double-circuit 230-kV transmission line from the Lauzon to Lakeshore transformer stations, expected to be in service by 2032.

Hydro One ( HRNNF ) will build the line in partnership with proximate First Nations who can invest in a 50% equity stake in the transmission line component of the project.

Once complete, the proposed line is expected to deliver reliable, clean electricity from the first of four small modular reactors (SMRs), enough to power the equivalent of 300,000 homes.
