According to historian Mike Filey, Wilson Avenue is a misspelling of Arthur L. Willson, who was a clerk and treasurer of York Township for over twelve years around 1875.

Following the opening of the subway extension into York Region in 2017, new commuter parking lots are available farther north at stations like Highway 407 and Pioneer Village.

[13] The subway station building is a simple enclosed concrete structure built within the median of Allen Road where it crosses over Wilson Avenue.

The mezzanine level connects by a maze of tunnels to the bus terminal, a kiss-and-ride facility and four commuter parking lots with a total of 2257 spaces.

[14] An additional island bus platform, no longer needed for the reduced number of connecting buses after the line was extended to Sheppard West Station,[6] was mothballed and now serves as a storage area.

Large events at the park, such as World Youth Day 2002 and Molson Canadian Rocks for Toronto in 2003, have resulted in heavy use of Wilson station.
