Unionville

Unionville GO Station is a train and bus station in the GO Transit network located in Markham, Ontario, Canada. It is a stop on the Stouffville line. The station is also served by Highway 407 East Express buses, which run westbound to Highway 407 station, northbound to Mount Joy GO Station, and eastbound to the Oshawa GO station.

By late May 2022, the station had acquired a second track, a turnaround track and an island platform to support future all-day, two-way service on the Stouville line. In future, GO trains will run every 10 minutes to Unionville and every 30 minutes to Mount Joy GO Station.
