The Early Works portion of the GO Expansion project is one of three blocks of works to be done to accommodate two-way, all-day transit throughout the GTHA corridor.
There are over 50 individual projects included in the early works program, including 40 smaller projects delivered as Design-Build or Design-Bid-Build, along with 12 larger projects delivered as Build-Finance and Design-Build-Finance. The latter includes the Davenport Diamond Rail Grade Separation Project, for which the winning bidder was selected in July 2019, and the Highway 401 Rail Tunnel, which began construction in March 2019, and the Stouffville Corridor Stations Improvement project. The program also includes the Union Station Enhancement project, which will see construction of a new South Concourse, track expansion east of the station and replacement of the 90-year-old signalling system with new state-of-the-art signals, communications, power supply, CCTV, and SCADA systems.
