MimicoGO Station is a railway station in the GO Transit network located in the Etobicoke area of Toronto, Ontario, Canada. It is a stop on the Lakeshore West line train service, serving the Mimico neighbourhood. The small station building is situated north of the tracks on the east side of Royal York Road. The building is connected by a tunnel under the tracks and stairs to the platforms, which are therefore not wheelchair accessible. There is an additional bypass track which runs between the platforms and another two tracks on the south side, which access Willowbrook Yard. This station and Long Branch are the only two stations on the Lakeshore West line which are not fully accessible. A modernization project began in August 2013 and was completed by 2018. It included the expansion of the platforms to fit 12-car trains, an expanded parking area, a pedestrian tunnel to Manchester Street, and a new station building.
It was the building of the first railway in Ontario in the 1850s between Hamilton and Toronto through what would become the Town of Mimico that led to the first plan for a town at this location. A Mimico Station was built on the north side of the tracks just south of Mimico's Christ Church on the east side of Church St at the end of Windsor Street. This development meant the name Mimico became more associated with the area where the railway crossed the Mimico Creek to its station on Church St rather than the former Mimico at the Mimico Creek and the early Highway; Dundas. Nevertheless, the 1856 subdivision plan for Mimico largely failed and it was after the more successful 1890 plan for a Town at Mimico the 'old' Mimico Railway Station building, constructed by the Grand Trunk Railway was built in 1916 as well as the Windsor Hotel. With the creation of the Government of Ontario's regional train GO service a new station was constructed on the site of the original 1856 Mimico Station, north of the tracks on the east side of Royal York just south of Christ Church. The 1916 Mimico Station deteriorated and was close to demolition when it was saved by community volunteers and moved to a new permanent location in Coronation Park at the northwest corner of Judson St and Royal York Rd in 2007. The building is now being restored with the intention of converting it into a local museum.
