The City of Toronto and the TTC are planning for the "Relief Line", a future rapid transit line that would connect downtown Toronto to the Bloor-Danforth Subway east of the Don River. It will assist in relieving crowding on the Yonge Subway line and the Bloor-Yonge interchange station as well as provide riders with more travel options.

The Relief Line Project Assessment will assess station locations and route alignment for the new rapid transit line. Plan to be involved with this important project. Join the project mailing list to be kept informed of project milestones and opportunities to participate.
