Train Shed Roof Revitalization

The renovation of the train shed (the roof covering the platforms and tracks) is a major component of the Union Station renewal project. The objective is to renovate and restore the east and west portions of the shed totaling approximately 30,000 square metres (300,000 square feet) and to replace the central 5,000 square metres (50,000 square feet) of the train shed with a large glass atrium. The train shed is a designated heritage structure, so we worked with Parks Canada in the overall design, ensuring that the heritage character will be preserved.

The completed glass atrium floats over the tracks, providing daylight at platform level and a visual connection from the station to the waterfront.

The work will be done in phases to minimize disruption to daily train service.

The ongoing phased work - over two tracks at a time, from south to north - include installation of a new train shed roof over the area, and repairing and restoring the historic steel structure.
