Relief Line South Environmental Project Report Completed

We are pleased to advise that the City of Toronto and Metrolinx, as co-proponents, have completed an Environmental Project Report (EPR) for the Relief Line South in accordance with the Transit Project Assessment Process (TPAP) under Ontario Regulation 231/08. View the Notice of Completion.

The Relief Line South is a new subway line that will connect the Yonge-University-Spadina Subway (Line 1) downtown to the Bloor-Danforth Subway (Line 2). This transit project 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.

The EPR provides details of the project, including the preferred alignment and stations, existing and future environmental conditions, impacts, mitigation strategies and monitoring measures. The EPR will be available for review from August 14, 2018 to September 13, 2018 on the project website ( and at multiple public locations, as listed in the Notice of Completion. The Notice of Completion provides further details regarding this review period and the process for submitting comments.

Further design work is currently underway. At its meeting May 24, 2017, City Council authorized advancing preliminary design (15-30%) with a report back on updated cost estimates in Q4 2019. This work will be advancing over the next 18 months and will include further opportunities for public consultation.
