Waterfront East LRT

The Waterfront East LRT, formerly known as the East Bayfront LRT, is a planned Toronto streetcar line that would serve the East Bayfront and Port Lands areas in Toronto, Ontario, Canada. It would run from Union station under Bay Street and along Queens Quay and Cherry Street to a new loop along Commissioners Street east of Cherry Street on Ookwemin Minising. It would complement the existing 509 Harbourfront service that connects Union Station to Queens Quay west of Bay Street. Longer-term plans are to extend the East Bayfront line from Cherry and Commissioners Streets to the planned East Harbour Transit Hub along GO Transit's Lakeshore East line and the planned Ontario Line.

The Waterfront East LRT Extension is a City of Toronto project to develop the East Bayfront LRT. The project involves both Waterfront Toronto and the Toronto Transit Commission. The proposed line is part of the Waterfront Transit Network which also includes the Waterfront West LRT.

As of July 2025, the project's design was 60 percent complete. In 2024, the project cost was estimated at $2.67 billion over 10 years. However, there was no commitment for funding from the provincial or federal governments. Design work would cost the city $135 million. If construction were to be funded, the line could open in the early to mid-2030s, according to planning staff. In 2023, planners had hoped for a partial line opening along Queens Quay East between 2030 and 2033 but with Union station bypassed. The project would have fully opened sometime between 2032 and 2035.
