Stouffville Line Closure – June 6-7, 2026

This past weekend, we closed the Stouffville Line to complete important construction work that will support faster, more frequent GO service. 

During the planned service disruption, crews carried out work in preparation for a future track diversion as part of the Finch Avenue East Underpass. This included stripping, grading, sub-ballast placement and compaction, and installing drainage elements.

Work was also conducted within the rail corridor surrounding Union Station, including replacing mud with fresh ballast and changing rail ties. In addition, crews carried out essential maintenance on the UP Express tracks to ensure the infrastructure remains safe and reliable.

We know weekend track closures are frustrating, but they are a necessary component to expanding GO and building a better, more reliable transit system. When the tracks are closed, there is more time to complete larger tasks, as opposed to completing the work during multiple overnight slots.

These planned service disruptions help us build a faster, more frequent, and safer network – not just for today, but for future generations too.   

To our customers and communities – thank you for your patience as we work to expand GO service.

Metrolinx is transforming your line from a commuter service into an all-day, rapid transit network. GO service is expanding to serve you better, with more frequent service, more stations, cleaner technology, and more connections.  

With the Stouffville line GO Expansion, we’re bringing you two-way, all-day service to core segments of the network, as well as access to new stations and transit connections on your line. This will mean more trains, more often – from Stouffville to Markham, Scarborough, and Toronto, giving you transit options for doing the things you love, wherever they’re found in the region. 

To keep these plans on track, we sometimes work overnight and on weekends, building and updating rail infrastructure, renovating GO stations, building new train platforms and more. Learn more about GO Expansion.

We aim to provide you with plenty of notice when we need to adjust service for construction activity. Please plan your trip in advance.

Work may be adjusted, rescheduled, or extended due to weather conditions or unforeseen circumstances.
