Hydro-Québec is launching construction on a new substation in Côte Saint-Luc, backed by a $740 million investment. The project, which includes an 18-km transmission line, began in 2018 and aims to improve service quality and increase power system capacity for Côte Saint-Luc, Côte-des-Neiges-Notre-Dame-de-Grâce, Hampstead, and Montréal-Ouest.

Preparatory work is underway, with construction set to start in June 2026 and commissioning anticipated by 2029. Hydro-Québec is also upgrading distribution systems due to recent outages, having increased capacity on two lines and replaced a transformer at Hampstead substation. Public collaboration is emphasized for the project's success.
