The Process

The City of Toronto, in partnership with the TTC, is undertaking the Relief Line Project Assessment. This study will evaluate route 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. 

The Relief Line Assessment Study includes several inter-related phases of work, including:

  • Phase 1A - Review of Proposed Terms of Reference and Development of a Detailed Public Consultation Plan;
  • Phase 1B - Problem Statement and Rationale for the Project;
  • Phase 2 - Develop "long list" of options and evaluation criteria;
  • Phase 3 - Evaluate options to produce "short list"; and,
  • Phase 4 - Evaluate "short list" of options, to produce draft recommendations.

Illustration of the five phases of the study process

Upon completion of the Relief Line Project Assessment, a decision will be made as to whether the project will proceed through the Transit Project Assessment Process for final review and approval.

The Relief Line Project Assessment includes a number of attributes that are appropriate for a project of this magnitude and complexity, including development of a Terms of Reference that defines the scope of the work that will be undertaken and a robust public consultation program that will be designed to maximize outreach and public input to decision-making in a participatory public engagement process.

The Relief Line Assessment Study will be further reported to City Council at key milestones, following Phase 1A and following Phase 4 (prior to initiating a final review through the Transit Project Assessment Process).
