Ontario Building New Transmission Lines to Power Growth Across the Province

June 6, 2025

The government announced one of the largest transmission investments in the province’s history. We’re building two new transmission lines and two major transmission upgrades — ensuring the province has the power it needs to meet growing energy demand to build new homes and support economic growth.

Our plan to significantly expand energy infrastructure is an important part of our work to protect Ontario by securing reliable and affordable energy that can power economic growth and reduce Ontario’s reliance on energy providers from outside the province.
