TORONTO - Infrastructure Ontario (IO) and Metrolinx announced today progress to design, build and finance the Union Station Enhancement project continues with the prequalification of two teams. Infrastructure upgrades are required to accommodate the planned expansion of GO Transit rail service, which link into Union Station as the major transit hub in the City of Toronto.

Teams were selected based on criteria identified in the Request for Qualification (RFQ) process including, applicable design and construction experience and capacity to finance a project of this size and complexity.

The prequalified teams are:

EllisDon Infrastructure Transit

  • Constructor: EllisDon Civil Ltd.
  • Designer: AECOM Canada Ltd.
  • Financial Advisor: EllisDon Capital

Graham Construction Rail Solutions

  • Constructor: Graham Construction & Engineering LP

This project is part of Metrolinx's work in support of GO Regional Express Rail (RER). GO RER will provide faster, more frequent and more convenient transit service across the Greater Toronto and Hamilton Area (GTHA), including electrification of core segments of the GO rail network by 2024-25. The program will provide new travel choices for commuters, significantly increase transit ridership, cut journey times and help manage congestion across the Greater Toronto and Hamilton Area.

Major infrastructure updates are required to bring this level of service to communities across the region, including: adding track, modifying GO stations, improving rail crossings, building required systems for electrification and adding new locomotives and train control systems.

Ontario is making the largest infrastructure investment in hospitals, schools, public transit, roads and bridges in the province's history. To learn more about what's happening in your community, go to
