Line 1 Yonge–University has part(s) Osgoode
Line 1 Yonge–University is a rapid transit line on the Toronto subway. It serves Toronto and the neighbouring city of Vaughan in Ontario, Canada. It is operated by the Toronto Transit Commission, has 38 stations and is 38.4 km (23.9 mi) in length, making it the longest line on the subway system. It opened as the "Yonge subway" in 1954 as Canada's first underground passenger rail line, and was extended multiple times between 1963 and 2017. Averaging over 850,000 riders per weekday, Line 1 is the busiest rapid transit line in Canada, and one of the busiest lines in North America.Names and terminal designation
On the Yonge portion of the line, nearly all stations located at cross streets are named after said streets, while on the University portion, they are either named for local landmarks with the cross street subtitled below (e.g. Osgoode – Queen Street) or after cross streets but with a "West" suffix for stations at streets that have counterparts along Yonge, though Dundas West station is on Line 2 Bloor–Danforth. The pattern of using landmarks as station names was exclusively used on the original (southern) section of the University branch, and the West designated street-naming convention is typically used on the former Spadina (northern) section. The two interchange stations on the University branch where it intersects Line 2 Bloor–Danforth are named St. George and Spadina after the north–south cross streets of Line 2, which runs below Line 1 between these stations. Due to various factors, some stations along the Spadina portion are named, formerly were named, or are proposed to be renamed using landmark or district names, albeit without subtitles: the stations at Steeles Avenue and Highway 7 (which have no corresponding stations along the Yonge branch) are respectively named "Pioneer Village" (after the nearby Black Creek Pioneer Village) and "Vaughan Metropolitan Centre" (after Vaughan's new downtown core, based on the precedent set by North York Centre and Scarborough Centre stations). Sheppard West was originally called "Downsview" but was renamed in 2017 to avoid confusion with the adjacent new Downsview Park station, and Eglinton West will be renamed "Cedarvale" (after the Cedarvale neighbourhood to the south) when it becomes an interchange station with the opening of Line 5 Eglinton in 2022.
