The Transit Project Assessment Process (TPAP)

The Transit Project Assessment Process

Status

Since July 2015, Metrolinx has commenced the pre-consultation phase of the Transit Project Assessment Process (TPAP) for network electrification. The TPAP is an expedited Environmental Assessment (EA) process involving a pre-consultation phase followed by a regulated 120-day TPAP phase whereby the environmental effects of the project will be analyzed. 

To date, this work has involved comprehensive baseline conditions data collection within the project Study Area (see map below) which encompasses six GO rail corridors, including potential locations for the required electrical power supply and distribution facilities: 

  • Union Station Rail Corridor
  • Lakeshore West Corridor - Strachan Avenue to Burlington
  • Kitchener Corridor - UP Express Spur to Bramalea
  • Lakeshore East Corridor - Don Yard Layover to Oshawa GO Station
  • Barrie Corridor - Parkdale Junction to Allandale GO Station
  • Stouffville Corridor - Scarborough Junction to Lincolnville GO Station

As part of the pre-consultation phased of the TPAP, Metrolinx is holding a first round of public meetings throughout February/March 2016.

Environmental Studies

Environmental studies are being carried out as part of the TPAP to examine the effects of the electrified system on the environment.

The results of these studies will be presented as part of the second round of public meetings and will be available for public review within the Environmental Project Report.
