Transit Project Assessment Process (TPAP), Don River to Scarborough GO Station, Public Meeting #2


Metrolinx is transforming the way the region moves by delivering the largest transit infrastructure program in Canadian history to keep the region moving today and tomorrow. The Greater Toronto and Hamilton Area (GTHA) is now home to nearly 7 million people and heading towards 9 million by 2041. To address the urgent transit needs of the GTHA, the Province of Ontario committed to implement more GO service and make other infrastructure improvements to the GO system to help create new transit connections and faster service across the region. By 2025, electric trains will be running every 15 minutes or, all day and in both directions, within the most heavily travelled sections of the GO network.

The Project

Metrolinx is completing a Transit Project Assessment Process (TPAP) under Ontario Regulation 231/08 made under the Environmental Assessment Act, to evaluate expanding and improving the Lakeshore East GO rail corridor between Don River and Scarborough GO Station in the City of Toronto.

The project involves:

  • Addition of a 4th track between the Don River Bridge and the Scarborough GO Station
  • Widening of three (3) bridges: Woodbine Avenue, Warden Avenue and Danforth Avenue
  • Modifying underneath the Birchmount Road Bridge
  • Modifications at Danforth GO Station to improve access
  • Retaining walls
  • Three (3) culvert extensions: east of Coxwell Avenue,east of Kennedy Road and Scarborough Junction

The Process

The TPAP is a proponent-driven, self-assessment process that provides a defined framework to follow in order to complete the accelerated assessment of the potential environmental effects and decision-making within a 120-day regulated assessment timeline. Following this period, the regulation provides an additional 30-day public and agency review, and a further 35-day Ministry of the Environment and Climate Change (MOECC) review. Prior to the commencement of the TPAP, introductory pre-planning activities take place. These activities include the study of existing environmental conditions and potential environmental effects of the Project across the natural environment, socio-economic environment, cultural environment, and traffic and transportation, as well as public and stakeholder consultation. As part of the TPAP, an Environmental Project Report (EPR) is being prepared.
