The Union Station Bus Terminal is part of GO Transit's facilities at Union Station in downtown Toronto, which is the hub for GO Transit's commuter rail service. The bus terminal opened in 2003 to replace the on-street facility in front of the railway station, relieving the traffic congestion on Front Street, and to accommodate GO buses moved from the Toronto Coach Terminal. Facilities available are: ticket counter/machines, newsstand/snack bar, public washrooms and a heated waiting area.
The bus terminal is located on the east side of Bay Street, directly across the street from the railway terminal. An enclosed walkway above the street connects the bus terminal to the railway station concourse. There is also direct stairway access from the bus terminal to railway platforms 4 through 13 via the Bay East Teamway under the railway tracks.
The site of the Union Station Bus Terminal was once occupied by a small passenger depot and more recently former CP Express & Transport building. Most of the old structure was demolished with a dock door retained and limestone fascia stored. The bus terminal sees an average of 7,000 passengers on week days.
One bus, the Hamilton Express, serves this terminal throughout the day, while other routes are connected to the rail corridors, with no bus service during the weekday peak hours, when the trains are in operation. Due to height restrictions on the approaches to the terminal, all buses plying these routes are single-decker buses or special low-height double-decker buses.

Local Toronto Transit Commission services use Union Subway Station for the Yonge–University–Spadina subway line and streetcar routes 509 Harbourfront and 510 Spadina. TTC bus routes 6 Bay  and 72 Pape  use curbside stops on the streets nearby.
Metrolinx announced plans to move the current terminal to a new complex located to the south of the current location, on the opposite side of the rail corridor, by 2018. This new terminal, which will expand capacity from 7 to 14 bays and be able to accommodate GO's fleet of double-decker buses, will be housed in a complex of office towers and elevated park over the rail corridor. The relocation of intercity bus service, such as Greyhound and Coach Canada, from the Toronto Coach Terminal to the new station is under negotiation.

Low-height double-decker buses will ease crowding on some of our busier trips and will be able to serve four terminals that can only currently be served by single-level buses due to height restrictions — Hamilton, Yorkdale, York Mills and Union Station.
