The Project

The Relief Line Project Assessment Study will assess alignment and station location options for a new rapid transit line connecting the Yonge-University-Spadina Subway (Line 1) downtown, south of Gerrard, to the Bloor-Danforth Subway (Line 2) east of the Don River, between Broadview and Coxwell.

City Council has approved the study’s terms of reference and public consultation plan. The study is scheduled for completion by late 2015 or early 2016.

The Relief Line Project Assessment Study process will:

  1. Identify and evaluate alternative routes and station locations, while engaging the public and stakeholders throughout the process. A preferred solution will be recommended. Measures required to mitigate environmental impacts associated with the recommended solution will also be identified; and,
  2. Document the study findings and recommendations in the form of a Draft Transit Project Assessment Environmental Project Report (EPR). The draft report will require approval by City Council.

Final approval of the EPR would occur through an environmental assessment process for transit projects known as the Transit Project Assessment Process (TPAP).  TPAP provides a framework for an accelerated, focused consultation and objection process for completing the assessment of potential environmental impacts of a transit project, so that decision making-making can be completed within six months.  Only issues concerning matters of provincial importance and aboriginal or treaty rights will be considered by the Minister of the Environment and Climate Change through the objection process.   

The study area includes the central business district in downtown Toronto, south of Gerrard, and extends to the east across the Don River to east of Coxwell Avenue, then north to the Bloor-Danforth Subway.

Extensions of the Relief Line will be the subject of future studies. A potential northern extension, from the planned connection with the Bloor-Danforth subway (Line 2) east of the Don River, would provide a connection with the Eglinton Crosstown LRT in the vicinity of Don Mills Road. A potential western extension would link downtown with the Bloor-Danforth Subway (Line 2) somewhere between Lansdowne and Keele Stations.
