Construction at the station is ongoing to facilitate double tracking, with an additional platform to be added to allow for enhanced all day service on the Stouffville line. Other enhancements will include platform canopies, two pedestrian tunnels with elevators, a larger parking lot, ramps instead of stairs from the parking lot and more bicycle storage.[3]
Old Unionville Station

The original Unionville Station was opened in 1871 by the Toronto and Nipissing Railway. The railway line and station were acquired in succession by the Midland Railway of Canada in 1882, the Grand Trunk Railway in 1884 and Canadian National Railway in 1923. Canadian National served the station until 1978; GO Transit used the station from 1982 to 1991.[4] GO train service ended at the station on Friday May 3, 1991, and service began at the current GO station the following Monday, May 6.
The old station building has been restored and is now used as a community centre.[4] Like Markham GO Station, this station features classic Canadian Railway Style with elements of Vernacular Carpenter Gothic architecture of the 19th Century. It is located on Station Lane, near Main Street Unionville. While a platform exists it is fenced off from the rail line to indicate it is not an operational station.
The current station was built in 1991 to replace the old Unionville Station. The newer station was renovated and re-opened in April 2005 and accessed by a service road from Kennedy Road north of Highway 407.

Viva service began on October 16, 2005, with buses stopping near Kennedy Road. Because the nearby Enterprise Drive was not finished when Viva services in the area began, this station served as a temporary station until November 19, 2005. During this time, both Viva Purple and Viva Green buses had to go on a detour on Highway 407 nearby. Viva Pink services were added on January 2, 2006.
Unionville Station is the eastern terminus of peak services on the Viva Pink services to Richmond Hill Centre and Finch station. Viva Pink, Viva Green, and Viva Purple usually serve Unionville Station. However, due to the COVID-19 pandemic, Viva Pink and Viva Green services were temporarily suspended.
