A major transformation is underway at Union Station, which will reshape Canada’s busiest transit hub to support increased capacity and improve passenger flow. 

Through the Union Station Enhancement Project, we’re modernizing the station while preserving heritage features — improving platforms, adding more access points, and building a new concourse that will make the station less crowded, more convenient, and more comfortable. 

Crews are hard at work pouring concrete for the track slab, forming wider stairs, installing plumbing and electrical systems for the new concourse, constructing mechanical rooms, and more. 

Check out the video below to go behind-the-scenes and see the progress happening on site.
