AtkinsRealis and Bird Construction, have entered into an alliance development agreement to work collaboratively with Metrolinx to deliver the East Harbour Transit Hub: a new interchange station that is part of a broader transit-oriented community plan for Toronto. AtkinsRealis is partnered with Bird under the Rail Connect (RC) Partners joint venture. Under the alliance development agreement, services include optimizing the design solution, preparing detailed estimates for resources, costs and schedules, preparing a Project Proposal, finalizing the Project Alliance Agreement, and performing Early Works.

The East Harbour Transit Hub will support local transit needs in the community and regional connectivity, through the incorporation of the GO Train, Ontario Line subway and future Toronto Transit Commission (TTC) light rail transit. Service levels planned as part of GO Expansion would see a GO train arriving as frequently as every five minutes.
