About The Project

The Blue Line Extension project will add approximately six kilometres of track and five new stations to the current 12-station Blue Line, one of four Metro lines that runs through the Greater Montreal Area. The extension will run along Jean-Talon Street, ending east of Highway 25. Mobilization of the first excavation sites for the tunnel boring machine began in the Fall of 2024, along with site mobilization and preparations for the excavation of Langelier station. More construction will follow gradually over the course of 2025.
