Environmental Assessments and Addendums under the Transit Project Assessment Process
To support the GO Expansion program, Metrolinx has identified various infrastructure requirements including track and switches, layovers, and electrification to achieve established service level targets across the network. New infrastructure involves carrying out Environmental Assessments (EA) and EA Addendums under the Transit Project Assessment Process (TPAP) (Ontario Regulation 231/08).
GO Expansion is intended to provide more service with more frequent and faster trains, improved and new stations, and seamless connections to a regional rapid transit network. As part of the GO Expansion program, Metrolinx has identified the need to reduce the number of road and rail at-grade crossings along the corridors to enhance safety, on time performance, operational flexibility/reliability and reduce traffic conflicts.
Through the Network-Wide Structures Project, road-rail grade separations and crossing improvements have been proposed along various GO rail corridors, and include:
Wellington Street East Grade Separation on the Barrie Corridor in the Town of Aurora
McNaughton Road Grade Separation on the Barrie Corridor in the City of Vaughan
These projects will address the at-grade crossings, accommodate rail line expansion including construction of new track, and assess proposed options for road-rail grade separation at these locations.
A Transit Project Assessment Process (TPAP) is a focused impact assessment process created specifically for transit projects. The process involves a pre-consultation phase followed by a regulated up to 120-day phase and includes consultation, an assessment of positive and negative impacts, an assessment of measures to mitigate negative impacts and documentation.
A TPAP ensures that the natural, social, cultural, and economic environments are protected and any potential adverse effects from proposed infrastructure are either avoided, mitigated or minimized.
Public, stakeholder, and Indigenous consultation occurs throughout the process.
The above new transit infrastructure is being assessed through the TPAP under Ontario Regulation 231/08 - Transit Projects and Metrolinx Undertakings, as an Addendum to a previously completed and approved TPAP.
