TORONTO - The request for proposals (RFP) stage has closed for prequalified teams to submit their proposals to design, build and finance the Highway 401 Rail Tunnel project, as part of the GO Regional Express Rail (RER) program.

Following a fair, open and transparent request for qualifications process, three teams -
Kiewit, TK Linx, and Toronto Tunnel Partners - were prequalified and invited to respond to a request for proposals in February 2017. All three teams have submitted their proposals by the RFP deadline.

Over the next several months, Infrastructure Ontario and Metrolinx will evaluate the proposals and a successful proponent is expected to be announced in Fall 2017. A fairness monitor is overseeing the entire procurement process.

The project includes construction of a second tunnel under Highway 401/409 to accommodate two tracks, future signaling, communications infrastructure, and replacing footings of retaining walls that support the ramp from eastbound Highway 409 to eastbound Highway 401.

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, visit

Quick Facts:

  • The project is being delivered using Infrastructure Ontario's Alternative Financing and Procurement model, which transfers risks associated with design, construction and financing of the project to the private sector.
  • This work on the Kitchener GO Corridor is part of a larger, system-wide plan to improve overall GO Transit service, including the delivery of GO Regional Express Rail (RER) by 2024-25. To support transit improvements, Metrolinx will be undertaking major infrastructure upgrades, including additional track, GO station modifications, improved rail crossings, required systems for electrification, and new locomotives and train control systems to enable more frequent service.
