Construction work of underground lines by Hydro-Québec near the Lachine Canal

Montréal (Quebec), November 17, 2015 – In order to meet the growing needs for electricity and ensure the long-term sustainability of facilities, Hydro-Québec is building new underground power transmission lines between Viger and De Lorimier substations, and Atwater and Maisonneuve substations. This work will cause hindrances and deviations of the Lachine Canal’s path close to the work zones located near Mill, De La Commune and Wellington streets, and the Atwater Tunnel.

Work should start during the week of November 16, 2015 and end by the end of December 2015. Appropriate signage will remain in place for the duration of the work.
