Hydro One Community Open House - Sudbury-Barrie Transmission Line

Hydro One is holding a community open house on Wednesday, April 15, 2026, from 4 to 7 p.m. at Centennial Arena in Hanmer, to engage with the public on the proposed Sudbury-Barrie Transmission Line.

The proposed priority project is a new single-circuit, 500-kilovolt (kV) transmission line that will span approximately 300 kilometres from the Hanmer Transformer Station (TS) in Sudbury to Essa TS near Barrie, including station facility expansions. The line is expected to be in service by 2032.

We encourage all those who are interested or have opinions on the project to attend. If you are unable to attend the in-person open house, they will be holding a virtual community open house on Tuesday, April 21, 2026 from 6 to 7 p.m.

You can learn more about the project and register for the virtual open house HERE.
