The Ontario Line - Neighbourhood Updates - East

The following maps show refinements to the alignment, or route of the line, and the proposed location of station platforms. Station entrance buildings and initial designs will be shared as new information is available. Teams have been studying how to speed up delivery, reduce building costs, minimize community impacts and improve connections for customers.

The portion of the Ontario Line where the trains will run above ground in the GO Lakeshore East Corridor is being considered in coordination with GO Expansion.


In the joint corridor (a shared railway where Ontario Line will run parallel to GO), early works within and along the rail corridor will proceed ahead of station and track construction. Planned early works, from Eastern Avenue to Logan includes:

  • GO rail corridor expansion
  • Installation or upgrading of vegetated slopes or retaining walls and noise barriers next to the corridor, where appropriate
  • Relocation or protection of utilities
  • Construction of new Ontario Line bridges on each side of the existing Queen, Dundas and Logan bridges

This work will proceed following an early works environmental assessment and related community consultations, including consultations with Indigenous communities.
The Ontario Line tracks will run on either side of four (three existing and one new) GO train tracks. Significant design and engineering efforts have been made to ensure the six-track railway does not significantly impact bordering properties or other ongoing infrastructure projects. Using the existing rail corridor and streamlining Ontario Line construction work with planned GO Expansion means we can keep mostly within an existing footprint and minimize impacts to surrounding neighbourhoods.

Early works will begin in 2021. More details, including scope of work and timelines, will be shared as procurement advances.

To cross the Don River, two bridges will be added to either side of the existing rail bridge, with space for tracks going in both directions. The current plan for this area is to also provide pedestrian and cycling connections across the Don River to ensure communities continue to develop and thrive with improved transit.
Early designs envision clean and simple structures that are similar to the iconic Humber Bay Arch Bridge in the west end of the city, adding a bookend in the east. They will contribute to the other exciting revitalization efforts that are underway in the area.

Early works will begin in 2021.

map of the East Harbour Station

Just east of the Don River and north of Lake Shore Boulevard, a station at East Harbour will be an important transfer and interchange station; accommodating GO operations, a planned extension of the Broadview streetcar, and Ontario Line service in a corner of the city that is poised for growth.
In many cases, people transferring from the GO Train to the Ontario Line will be able to walk straight from one to the other without having to go up or down a level.
Metrolinx is working with a development partner to deliver the East Harbour transit hub. The hub will be designed based on Metrolinx transit requirements to integrate the station with the future local developments. Designs are underway and will be shared as procurement advances.

  1. The station serving Leslieville and Riverside will help relieve congestion on the busy 501 Queen streetcar and give customers a faster way to get where they need to be, whether that’s downtown, the Danforth, or an array of other neighbourhoods along the line.

  2. With the station situated mostly to the south of Queen Street and spanning over the existing rail bridge, the popular Jimmie Simpson Community Centre will be able to continue operating throughout construction and beyond.
    Current plans envision maintaining streetcar service in these areas throughout the duration of the project, though there might be times when service is re-routed or reduced to accommodate construction work.

Early works will begin in 2021. Station construction will begin after financial close for the Northern Civil, Stations and Tunnel procurement package.

Metrolinx is committed to building noise walls along the rail corridor where the Ontario Line will run alongside the Lakeshore East GO trains. Noise walls, along with state-of-the-art vehicle technologies and strict maintenance practices, will mitigate noise impacts from both Ontario Line and GO trains.

Teams are still developing plans that will detail the exact locations, heights and proposed design treatments for the noise walls, which will be brought forward for consultation. Metrolinx will continue to seek community feedback on any proposed mitigations through the environmental assessment process. Public art surface treatments would be procured, funded, implemented and maintained by municipalities or other third parties.

map of the line segment containing Gerrard station
  1. The station and tracks at Gerrard will be integrated with the existing bridges over Gerrard and Carlaw Avenue. The slightly staggered placement of the south platform has been designed to accommodate the beginning of the tunnel portal and eliminate the need for a wider curve to the east to accommodate the turn north. As the train leaves the station, it will dip down into the tunnel to run under the GO tracks as they continue east.
    At Gerrard, the station will provide a connection to the 506 Carlton TTC streetcar and 72 Pape TTC bus.

Work is anticipated to begin after financial close for the Northern Civil, Stations and Tunnel procurement package.

  1. Launch shafts and portals will be constructed on the north and south side of the existing GO tracks for the beginning of the Ontario Line tunnels. From here, the tunnel boring machines will begin to work their way north, toward Pape Station.

  2. Much of the space to be used for the portal and construction is currently paved over for parking. Metrolinx will work with local business owners to minimize the impacts of construction on their properties.

Work is anticipated to begin after financial close for the Northern Civil, Stations and Tunnel procurement package.

map of the line segment containing Pape South
  1. By repositioning the station platforms at Gerrard, teams were able to eliminate a wide loop that would have been needed to allow proper curvature for trains to turn towards Pape. This will reduce travel times and lessen property impacts.
  2. As it descends, the tunnel is expected to run under a small corner of the Pape Avenue Junior Public School’s yard. The property will be protected, with access maintained throughout construction and robust safety standards in place.

Work is anticipated to begin after financial close for the Northern Civil, Stations and Tunnel procurement package.
