Osler is representing the Toronto Transit Commission (TTC) in multiple litigation claims involving construction and design of the Toronto-York Spadina Subway Extension Project.  The Toronto-York Spadina Subway Extension provides a critical extension for the existing Toronto Transit Commission subway system across the municipal boundary between the City of Toronto and the Regional Municipality of York.  One of these claims includes a claim for damages against TTC by Walsh Construction Company Canada in the amount of $218 million, as well as numerous claims by subcontractors and suppliers on the project.

The Toronto Transit Commission (TTC) is a public transport agency that operates bus, subway, streetcar, and paratransit services in Toronto, Ontario, Canada.  The TTC is the most heavily used urban mass transit system in all of Canada, and the third largest in North America, after the New York City Transit Authority and Mexico City Metro.

Osler’s litigation team is representing the TTC with a team consisting of Paul Ivanoff, Malcolm Aboud and Kevin O’Brien (Litigation).
