Metrolinx is bringing new all-day GO train service to the Stouffville line to help manage congestion, provide more transit options and improve commutes for families in eastern York Region and Scarborough.

Transportation Minister Steven Del Duca, Markham-Unionville MPP Michael Chan and Oak Ridges-Markham MPP Dr. Helena Jaczek visited Unionville GO Station in June to announce the new trains.

Starting June 26, new train trips will run approximately every hour in both directions during the midday and evening periods, from Monday to Friday between Unionville GO Station and Union Station. In addition, there will be one new morning and late evening weekday train trip between Lincolnville GO Station and Union Station, and two existing train trips will be extended from Unionville GO Station to Lincolnville GO Station. In total, there will be 17 new train trips per weekday, doubling the total number of weekly train trips from 85 to170 along the Stouffville GO corridor.

“Commuters have been asking for all-day GO service on the Stouffville GO line, and our government has listened. This and other future improvements will better connect people in the region to the entire GO network,” said Michael Chan, MPP for Markham-Unionville.

The new GO train trips will serve Kennedy, Agincourt, and Milliken GO Stations along the Stouffville GO corridor, which are not currently served by midday or evening GO Transit services.

By 2025, planned GO Train service on the Stouffville GO line will include two-way service every 15 minutes or better between Union Station and Unionville, two-way service every 60 minutes or better between Union Station and Mt. Joy during the midday and evening periods of weekdays as well as on weekends, and peak-period, peak-direction service on weekdays, at frequencies of roughly every 20 minutes or better, between Union Station and Lincolnville. The entire line will also be electrified.

Expanding service along the Stouffville GO corridor will support GO Regional Express Rail (RER). According to Metrolinx, GO RER will provide faster and more frequent service across the GO network and is the largest commuter rail project in Canada.
