Union station
Via Rail and Amtrak provide inter-city train services while GO Transit operates regional rail services. The station is also connected to the subway and streetcar system of the Toronto Transit Commission (TTC) at its adjacent namesake subway station. GO Transit's Union Station Bus Terminal, located in CIBC Square, is connected to the Union station by a enclosed walkway above Bay Street. The Union Pearson Express, which provides train service to Toronto Pearson International Airport, has a platform a short walk west of the main station building, accessible by the SkyWalk.
