All-day GO Train Service Coming to Stouffville GO Line

Ontario Adding More GO Train Trips to Help Commuters and Manage Congestion

Ministry of Transportation

Ontario 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 Scarborough and York Region.

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

Starting Monday, 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.

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

Ontario is making the largest infrastructure investment in hospitals, schools, public transit, roads and bridges in the province's history. To learn more about what's happening in your community, go to Ontario.ca/Build ON.

Increasing public transit to improve people's commute is part of our plan to create jobs, grow our economy and help people in their everyday lives.
