Stouffville Rail Corridor Grade Separations

Stouffville Rail Corridor Grade Separations - Proposed Infrastructure

To support the GO Expansion Program,  the Stouffville Rail Corridor Grade Separations TPAP is six (6) grade separations or road closures along the Stouffville rail corridor.

Purpose and benefits of grade separations

A grade separation separates the road from the rails, so that vehicles and or pedestrians can pass under or over a railway, without having to stop and wait for the trains.

Grade separations are essential to support transit expansion, and provide other community benefits, including:

  • Improved traffic flow and elimination of the potential for conflicts between trains and vehicles
  • Better connections and crossings for pedestrians and cyclists
  • Air quality benefits from reduced vehicle idling at crossings
  • Reduced noise from at-grade crossing signals and train whistles
  • Opportunities to bring roads up to new standards, by incorporating wider lanes, sidewalks, separated bike lanes, or improved lighting

Metrolinx is improving service as part of the GO Expansion Program by increasing train frequency and availability. The long-term goal and vision of the GO Expansion Program is to provide 15-minute two-way all-day service.

With trains planned to run every 15 minutes (a crossing every 7 minutes in one direction or the other), it is not possible to maintain at-grade crossings.

By grade separating the crossings, Metrolinx can increase travel speed and capacity on our rail corridors by allowing trains to freely pass over or under roads without the need for stoppages. Grade separations will support the growth of our cities by increasing traffic flow and transit capacity.

Proposed grade separations

The Project includes the following seven proposed grade separations and road closure:

City of Markham, York Region

  • Denison Street, Road Under Rail Grade Separation
  • Kennedy Road, Road Under Rail Grade Separation

City of Toronto

  • Passmore Avenue, Road Under Rail Grade Separation (deferred to future TPAP addendum)
  • McNicoll Avenue, Road Under Rail Grade Separation
  • Huntingwood Drive, Road Under Rail Grade Separation
  • Havendale Road, Road Closure with Multi-use Crossing
  • Progress Avenue, Road Over Rail Grade Separation (updated design in Round 3)

View the panels that describe the grade separations presented at the February 2020 Open Houses.

Based on the extent of potential property impacts along Progress Avenue and Passmore Avenue, Metrolinx undertook targeted engagement sessions with property owners within the Project Footprints of these two grade separations.

Due to ongoing COVID-19 concerns, these engagement sessions were conducted virtually. Representatives from the property owners, City of Toronto, LeighFisher Inc., Stantec Consulting Ltd., and Metrolinx attended the sessions. The purpose of the sessions was to provide an overview of the grade separations program and specific details of the grade separation proposed at Progress Avenue and Passmore Avenue, gather information regarding the current and future planned operations occurring at potentially affected properties, listen to and respond to concerns of the property owners, and provide an overview of the potential access road options.

Based on the feedback received during the engagement sessions, Metrolinx has made changes to some of the public access roads proposed at Progress Avenue. These changes are presented in the updated Progress Avenue panels.

For Passmore Avenue, while progress has been made on multiple fronts, there is still work to be done to agree on a solution that meets the needs of the city, businesses and GO Expansion. To account for the additional time needed for a design solution, Metrolinx will no longer be seeking TPAP approval for the Passmore Avenue grade separation as part of the ongoing Stouffville Rail Corridor Grade Separations TPAP. Metrolinx will prepare a future EPR addendum for the proposed grade separation at Passmore Avenue to address the outstanding stakeholder concerns.

Please note that the proposed infrastructure is based on reference design concepts that may be subject to change during the detailed design process.

Construction sequencing

The construction sequencing of each of the grade separations was considered in the Transportation Impact Assessment study. Considerations were made for the project which will form the constraints for determining each of the preliminary construction phases. View the highlights of the construction sequencing plan.
