In 1927, the TTC signed a contract with
Trinity College leasing a parcel of land at Bay and Edward Streets for an open air coach terminal. After purchasing the Bay/Edward property, construction on a permanent terminal building began in July 1931. An annex, the Elizabeth Street Terminal located at 130 Elizabeth Street, is located to the west of the main terminal. It was originally built in 1968 Through the 1990s,
GO Transit bus services gradually relocated to
Toronto Union Station, first to seven curb-side bus stops along
Front Street in front of the railway station, and then to the original Union Station Bus Terminal on Front Street, across Bay Street from the rail terminal. GO's Toronto to Hamilton Express bus route was the last to use the Elizabeth Street Terminal until Labour Day weekend of 2002 when it moved to the original Union Station Bus Terminal on Front Street. After the departure of GO Transit, the Elizabeth Street terminal only handled arrivals for the remaining bus lines. The bus bays on the south side of the building were decommissioned and the area converted into a
Green P paid parking lot. The waiting area and newsstand in the Elizabeth Street Terminal were closed in 2010 with only the bus platform on the north of the building remaining open to the public for bus arrivals. Due to limited space, buses would park overnight along Edward Street and Chestnut Street. A renovation of the main terminal building occurred in 1990, tripled the main terminal's floor space to 2,500 square metres, creating more seating for waiting passengers (250 seats rather than 100). This was done by demolishing the interior wall separating the main building from the bus bays and replacing it with a glass wall several metres to the west, reducing the space allotted for bus bays. The bus shed was configured into seven lanes, with room for two buses in each lane. The 40-seat
