GO updated the construction-related weekend train service closures.
Stouffville has two upcoming weekends in June and July that I am hopeful be used to bring more track between Kennedy and Unionville into service (sans Highland Creek bridge which was last estimated to be a summer 2026 deliverable).
A November closure for both Stouffville and LSE has been listed, which is a candidate for a 3rd track installation if the bridges and retaining walls are ready.
There’s a list of dates added for Barrie, Kitchener and LSW lines but I don’t follow those projects as closely because I’m not a regular rider on that part of the network.
Select your line to find out about planned construction in your area.
