As part of the GO Expansion Program, Metrolinx has identified various infrastructure required to achieve service level targets across the network.
The New Track & Facilities TPAP is one component of the GO Expansion Program that will follow a Transit Project Assessment Process (TPAP) (Ontario Regulation 231/08). New infrastructure being proposed as part of the New Track & Facilities TPAP includes:
three (3) new layover/storage facilities along various corridors; Don Valley Layover (Richmond Hill Corridor – City of Toronto), Walkers Line (Lakeshore West Corridor – City of Burlington) and Unionville Storage Facility (Stouffville Corridor – City of Markham);
new platforms at existing GO Stations;
new tracks/switches within existing Metrolinx Rights-of-Way (ROW);
modifications or upgrades to existing tracks within existing Metrolinx rail ROW;
bridge expansion/modifications; and
electrification of a portion of the Richmond Hill GO Rail Corridor up to Pottery Road in the City of Toronto.

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.
