Metrolinx, the Ontario provincial government agency that oversees transit expansion projects in the Greater Toronto and Hamilton Area, has launched the Eglinton Crosstown West Extension project, which will extend Line 5 Eglinton another 9.2-kilometres farther west into neighbouring Mississauga.
Metrolinx and Infrastructure Ontario have awarded four contracts, two for separate tunnel sections, one for an elevated guideway section and the other for systems, rail and stations (SRS). SYSTRA Canada, as a subcontractor to Trillium Rail Partners (TRP), will carry out Systems Engineering and Safety Assurance oversight on the quality of the technical SRS design deliverables.

SYSTRA Canada has already been involved in light rail and tramway projects in Gatineau-Ottawa and Quebec City.
