Current Work

The City of Toronto, Toronto Transit Commission and Metrolinx, are working collaboratively to progress the Relief Line South Project.  At its meeting May 24, 2017, City Council authorized advancing the project to the Transit Project Assessment Process (TPAP) and preliminary design (15-30%) based on the approved alignment and station locations with a report back in late 2019/early 2020. 

On October 17, 2018 the Minister of the Environment, Conservation and Parks signed a Notice to Proceed for the Relief Line South transit project in accordance with the Environmental Project Report (EPR). Following this, the City of Toronto, TTC and Metrolinx issued the Statement of Completion of the TPAP on October 24, 2018. The completion of the TPAP allows the project to proceed to construction. Preliminary design and engineering is currently underway.

On March 7, 2019, City Council approved the TTC's 10-year transit expansion capital plan that included funding to support a schedule improvement strategy for the project. This new funding will allow for early work opportunities such as:

  • property acquisition;
  • utility relocation; and
  • procurement of tunnel boring machines.

Further funding commitment to finalize design and proceed with construction of the project will still be required.
