Infrastructure Ontario and Metrolinx have awarded a fixed-price design-build-finance $245.5 million contract to upgrade Agincourt, Milliken, and Unionville GO stations on the Stouffville GO corridor.  The winning bidder, EllisDon Transit Infrastructure (EDTI), will deliver the project using Infrastructure Ontario’s Alternative Financing and Procurement model.  EllisDon constituents will provide financing and construction while WSP / MMM Group will be in charge of the design.  The project includes upgrades to tracks, platforms with canopies, new pedestrian connections, and new amenities at the three stations.

The scope of work also includes a new grade separation with a railway overpass bridge at Steeles Avenue.  Design work is expected to begin this month, with construction beginning in September 2018 and substantial completion planned for December 2020.         

The Stouffville Corridor Stations Improvement project is part of the larger GO Regional Express Rail (RER) program, one of the largest transit infrastructure investments in North America.  The Province of Ontario is investing $21.3 billion to transform the GO Transit Network from a commuter transit system to a regional rapid transit system, with electrified service on core segments, across the Greater Toronto and Hamilton Area over the next decade.  The number of weekly trips across the entire GO rail network is projected to grow from 1,500 to 6,000 by 2024-2025.
