The Project/
What's Happening Now?

Provincial funding for the Relief Line North is now in place to advance the planning and environmental assessment of this important rapid transit line extension, and work by Metrolinx, the City of Toronto and the TTC is underway. Concurrently, in 2018, the Transit Project Assessment Process (TPAP) for the Relief Line South will also be advancing, with preliminary design. Municipal and provincial funding is available to advance this work on the Relief Line South.

Metrolinx, the City of Toronto and the TTC have begun the planning work that will lead to the completion of a Transit Project Assessment Process (TPAP) for the Relief Line North.

The TPAP is a streamlined six-month environmental assessment process specific to transit projects in Ontario
to satisfy the requirements of the Environmental Assessment Act, Regulation 231/08.

This diagram shows the study phases and consultation rounds involved in the Relief Line North Project Assessment. We are currently in Study Phase 1, Consultation Round 1 which includes two steps: Step 1 - define the Project; and, Step 2 - identify a long list of station areas and corridor options. Consultation Round 2 also includes two steps: Step 3 - analyze options, including potential alignments and technologies, to identify a short list of station areas and corridor concepts; and, Step 4 - evaluate the short list of options through an Initial Business Case to determine a preferred alignment. Next, Consultation Round 3 includes the following two steps: Step 5 – develop a conceptual design for the project; and, Step 6 – determine phasing for construction and implementation. Finally, Consultation Round 4 takes place during Study Phase 2, which is the Transit Project Assessment Process including environmental approvals.

Phase 1 of the study will recommend the extent/ length of the Relief Line North, and the preferred type of rapid transit (i.e., subway and/ or LRT), route and station locations. This phase will also include the development of an Initial Business Case (IBC), which will be updated as the project is further developed.

Phase 2 of the study will include detailed environmental studies that will determine existing conditions, and potential environmental, socio-economical and archaeological impacts of the planned project, and then propose mitigation measures. After sharing the results of the environmental studies with the community, an Environmental Project Report will be developed and will be available for public and agency review. This phase will end with the completion of the TPAP, leading to the detailed design phase.
