Infrastructure Ontario and Metrolinx selected the HDR-led team to serve as technical advisor for the approximately $8.2 billion Ontario Line in Toronto. The nearly 10-mile, free-standing subway line, with 15 proposed stations, will run from Ontario Place/Exhibition Place through downtown Toronto to the Ontario Science Centre.
Expected to accommodate nearly 400,000 daily boardings, the Ontario Line will provide relief to TTC’s Line 1, serve fast-growing areas such as Liberty Village, and bring transit to underserviced priority neighbourhoods like Thorncliffe Park and Flemingdon Park.

Building a new subway line through the downtown core of the most populous city in Canada is complex. As technical advisor, HDR and its primary partners — Mott MacDonald, Stantec, Systra, and Comtech — will provide a wide range of planning, engineering, environmental, design, and construction oversight services with the goal of successful, timely project delivery.
Initial planning and design work has already begun for the Ontario Line. The assignment will add to HDR’s already extensive transit portfolio, including iconic projects in Los Angeles, New York, Seattle, Dallas, Honolulu, Denver, and more.
