Wilson station was opened in what was then the
Borough of North York as the last station in the 1978 subway line extension north from
St. George station. 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. Among Arthur Willson's accomplishments were writing a "municipal manual", "which has been found of practical value as a guide to those requiring a knowledge of municipal law", according to a history of the County of York. Wilson was the northwestern terminus of the Yonge–University line for eighteen years and a major hub for TTC bus service, but with the extension to (then named
Downsview) in 1996, many of the bus routes serving areas to the north were moved to the new station. Concurrent with the opening of the
Toronto–York Spadina Subway Extension (TYSSE) on 17 December 2017, this station became one of the first eight stations to discontinue sales of legacy TTC fare media (tokens and tickets), previously available at a fare collector booth. Presto vending machines were available to sell
Presto cards and to load funds onto them. On 3 May 2019, this station became one of the first ten stations to sell Presto tickets via Presto vending machines. In November 2018, construction began on three new elevators, automatic sliding doors, and a new accessible washroom, to make the station
wheelchair accessible. It was completed on 18 December 2020. By the late 1990s, over 2,000 commuter parking spaces were available. Two lots were declared surplus in 2013 and have been redeveloped. Until November 2024, 953 parking spaces remained at Wilson; however, in October 2021, the city government reached an agreement with developer
Tridel to build 1,484 new homes, a childcare centre and a new park on the main parking lot. Since 18 November 2024, only the Wilson Transit Road Lot with 72 spaces remains available. 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. ==Architecture and art==
