I would like to find out if the design of the project will allow for a fourth track to be added to the Lakeshore East line running east from Scarborough Go Station in the future?

Thank you for your interest on the Scarborough Junction Grade Separation Project. The project focuses on accommodating a previously approved new track extending north to Unionville along the Stouffville Rail Corridor but does not consider adding a fourth track along the Lakeshore East Rail Corridor to the east of Scarborough Go Station. Currently planned service increases will not require the addition of a fourth track east east of Scarborough Go Station. 

If future planning considers this addition, further assessment will be required to assess the potential for impacts, including to the rail corridor, existing bridges and surrounding properties.

When the bridge over St. Clair Ave (just north east of the Scarborough Go Station) is widened, will traffic under the bridge be impeded? If so, do we yet know by how much and for how long? For example, will it be reduced to one lane for a month? Six months? Traffic east-west along St. Clair (@Midland) has gotten noticeably heavier over the years (as development continues) making the commute to the station longer and longer. Obviously, traffic disruption is a part of any large project. Just wondering how much of a disruption to expect.

Construction staging plans are currently under development and will be finalized once a constructor is selected; however, it is anticipated that construction of the abutments will require closure of the delineated shoulder lanes, maintaining the use of the existing four lanes of traffic along St. Clair Avenue East (two in each direction). Pier construction will require closure of the centre two lanes with diversion of traffic to the delineated shoulder lanes. Therefore, two lanes of travel in each direction will be maintained as much as possible during construction.

The link is still broken (leads to the wrong file), one week into the short two-week commenting period. Any updates on when it will be fixed?

Thank you for your feedback and interest in our work and flagging this concern. We had some technical difficulties that were fixed during the open house. The materials are still available and you can also find the Scarborough Junction Overview roll plan here.

Why, after building the whitby facility , and taking over part of VIA rail's yard, and having the Don yard and Bathurst yard, is go adding layover facilities throughout the network? This will only congest an already busy network with empty trains trying to reach these facilities. And what is the rail-rail grade separation at Scarborough Junction? Currently no two rail lines cross each other here.

Thanks for your interest in the Scarborough Junction Grade Separation Project. Layover facilities are required to accommodate service expansion. With major investment in GO Rail infrastructure, Metrolinx will be quadrupling GO Rail service and nearly doubling GO Rail ridership. Layover/storage yards are strategically located throughout the rail network to achieve the targeted GO Expansion service levels by:

  • Reducing long-distance non-revenue trips
  • Accommodating train storage during off-peak hours
  • Reducing rail congestion
  • Allowing trains to be routinely serviced and cleaned
  • Providing flexibility for trains to operate more seamlessly across the network

Regarding the rail-rail grade separation, there is currently one track for the Stouffville Corridor, that is located north of Lakeshore East Corridor tracks. The Stouffville track does not cross Lakeshore East Corridor, however, the one track accommodates both northbound and southbound trains which is inefficient. A new track will be built at the Scarborough Junction heading north on the Stouffville Rail Corridor to achieve Metrolinx’s goal of providing 15-minute two-way service on the Stouffville Rail Corridor south of Unionville GO Station. The Scarborough Junction rail-rail grade separation has been proposed to remove the potential for train conflicts and meet future service targets. As such, the new second Stouffville track will drop below grade and cross under the Lakeshore East tracks before meeting with the existing Stouffville track.

The link to the "Scarborough Junction Overview" roll plan is broken, would you fix it?

There are three fields that you can fill out when asking a question in the public forum. The first is an option to provide a name, you can also choose to leave this box empty and remain anonyms. There is a field for you to ask a question that has limited characters as it becomes the heading for your question. This heading makes it easier for your neighbours to sort through and see your questions, giving everyone an opportunity to vote up and down on questions. The third field gives you the opportunity to provide additional information or context about your questions - this box does not have a maximum character threshold. All three fields will become a part of the public forum and will be shown after you submit a question. We look forward to hearing from you and answering any questions your might have about our work.

When I received the flyer for this online consultation, I rolled my eyes (hard) and was very skeptical. I'm prepared to eat my words. The early days of this online system have proven that it makes participation easier and the answers are thoughtful and not just standard-issue form answers. Thank you for your effort. It's appreciated. Keep up the good work.

Thank you for your kind words and feedback! Public consultation is an important part of the transit planning process and really helps inform our work. The online format has helped more people to be involved in the consultations. We are still learning how to adapt to the new format, and hope to improve with each engagement.
