Residents in Whitchurch-Stouffville who rely on the train should prepare for changes to their travel plans, as GO Transit will close the Stouffville line entirely on April 11 and April 12, 2026. The closure is required to perform maintenance on retaining walls along the rail corridor, with some service adjustments also taking place on the night of April 10.
During the weekend, passengers who normally use the train will need to use replacement bus service between Old Elm or Mount Joy stations and Rutherford station, with buses running via Unionville GO. From there, riders can connect to trains on the Barrie line to travel to Union Station. Because of construction work being done by the City of Toronto on the Don Valley Parkway, the Union Station Bus Terminal is closed, meaning buses cannot travel directly to downtown Toronto. GO Transit has confirmed that staff will be available at Rutherford station throughout the weekend to help passengers navigate these transfers.
This maintenance work is part of ongoing efforts by Metrolinx to update the rail line. While the agency has a long-term goal of transforming the route into an all-day, two-way rapid transit network, the project has faced challenges, including shifts in its construction partnerships and delays in the expected timeline for electrifying the line. Despite these hurdles, infrastructure improvements such as station upgrades at Agincourt, Milliken, Old Elm, and Unionville have been completed, and the installation of a second set of tracks between Kennedy and Unionville is nearing completion to support future growth.
Regular train service is set to resume on Monday, April 13, 2026. Commuters and weekend travelers are encouraged to plan for extra travel time while these maintenance activities are underway.
