Human Resources Business Partner

What Is The Opportunity?

Scarborough Transit Connect (STC) was selected by Metrolinx to deliver the Scarborough Subway Extension – Stations, Rails and Systems (SSE-SRS) package. The Scarborough Subway Extension will bring the TTC’s Line 2 subway service nearly eight kilometers farther into Scarborough. It will extend from Kennedy Station to Sheppard Avenue and McCowan Road, providing quick and seamless transit for those heading into and out of the downtown core and those travelling within Scarborough. The extension will replace Line 3 (the Scarborough RT), helping to reduce travel times and improve access to jobs, schools and other key destinations throughout the city.
