The Project/ Frequently Asked Questions

What is the Relief Line North?

The Relief Line North is a northerly rapid transit extension of the planned Relief Line South from Pape Station with the goal of connecting to existing/ future rapid transit, such as Line 5 Eglinton and Line 4 Sheppard.

The Relief Line North is being studied to help address a gap in our existing rapid transit network, offer alternative routes and relieve congestion on Line 1 Yonge and at interchange stations including Bloor-Yonge and Eglinton. See About the Relief Line North for more details.

Why is the Relief Line North needed?

The Relief Line North will provide another travel alternative, divert demand from Line 1 Yonge and at the Bloor-Yonge and Eglinton stations, and provide greater transit capacity to downtown. This means better connections for people to key destinations across the City, better access to businesses and jobs, and shorter, more comfortable transit commutes. See Why the Relief North is Needed for more details.

What is a TPAP?

A Transit Project Assessment Process (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. The TPAP includes consultation, an assessment of potential impacts, identification of measures to mitigate impacts and completion of an Environmental Project Report. Metrolinx, the City of Toronto and the TTC will work closely with key stakeholders, the public, agencies, Indigenous communities and all other interested parties throughout the TPAP to address questions and concerns.

The TPAP includes a 30-day public review of the final Environmental Project Report. Objections, if any, may be submitted to the Ministry of Environment and Climate Change during this time. This is followed by a 35-day period for the Minister to act.
