Still in the works - but unfunded. It would be a separate project, and is related to streetcar expansion on Queens Quay East and Bremner. The second platform for the subway station (also a separate project) is under construction though, and provides a direct connection from the new Yonge north platform to the streetcar loop.
Bremner is getting a streetcar? I had no idea of this proposal. I was under the assumption that it was only Queens Quay East that was getting new streetcar tracks.
