GO Transit buses, with transfers required for connecting TTC buses. The current underground TTC bus platforms and
GO Bus Terminal were built between 1985 and 1992 with the development of the
York Mills Centre, with the TTC platforms inside the fare-paid area. In 2007, this station became accessible with elevators.
