Current Work

The City of Toronto and Toronto Transit Commission (TTC), in partnership with Metrolinx, jointly announce that Notice of Commencement and Public Meetings for the Transit Project Assessment Process (TPAP) for the Relief Line South subway. This new subway line will connect the Yonge-University-Spadina Subway (Line 1) downtown to the Bloor-Danforth Subway (Line 2). This new subway line will help to relieve crowding on Line 1 south of Bloor, at the Bloor-Yonge Station, and on the surface transit routes coming in and out of downtown.

Toronto City Council has confirmed support for the Pape/Carlaw/Eastern/Queen alignment for the Relief Line (South) and eight station locations. In addition, Council has authorized commencing the TPAP, and advancing planning and design.

This project is the subject of a TPAP to satisfy the requirements of the Environmental Assessment Act. As part of the TPAP, an Environmental Project Report (EPR) is being prepared which documents the planning process involved and the details of the Relief Line (South), including existing and future environmental conditions, the preferred alignment, station location and bus terminal, construction methods, and impacts, mitigation and monitoring measures.
