As part of the GO Expansion Program, Metrolinx has identified various infrastructure required to achieve service level targets across the network.
The Scarborough Junction Grade Separation is one component of GO Expansion Program that will follow a Transit Project Assessment Process (TPAP) (Ontario Regulation 231/08).
The Scarborough Junction Grade Separation Project will facilitate the GO Expansion Program and accommodate the expansion of the service on the Stouffville Rail Corridor through grade separations and related infrastructure.
Reducing the number of road and rail at-grade crossings is essential to support transit expansion and will provide community benefits.
Infrastructure being proposed as part of this Project includes:
Rail / Rail Grade Separation of the Stouffville and Lakeshore East Corridors;
Midland Layover;
Corvette Park - Multi-use Crossing (Bridge or Tunnel);
Danforth Road - Rail Tunnel;
St. Clair Avenue East - Bridge Expansion; and
Modification or relocation of Scarborough GO Station Building.
Scarborough Junction Grade Separation is one Project that is part of the GO Expansion. To learn more about other GO Expansion projects, click here.

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.
