Union Station is a major railway station and intermodal transportation hub in Toronto, Ontario, Canada. It is located on Front Street West, on the south side of the block bounded by Bay Street and York Street in downtown Toronto. The municipal government of Toronto owns the station building while the provincial transit agency Metrolinx owns the train shed and trackage. Union Station has been a National Historic Site of Canada since 1975, and a Heritage Railway Station since 1989. It is operated by the Toronto Terminals Railway, a joint venture of the Canadian National Railway and Canadian Pacific Railway that directs and controls train movement along the Union Station Rail Corridor, the largest and busiest rail corridor in Canada.

Front Street is an east–west road in downtown Toronto, Ontario, Canada. First laid out in 1796, the street is one of the original streets of the Town of York. The street was laid out along the shoreline of Lake Ontario as it existed during that time. It remains an important street, with many important uses located along it, including the St. Lawrence Market, Meridian Hall, Union Station and the Metro Toronto Convention Centre. The eastern section of Front Street, in the West Don Lands, east of Cherry Street, is being rebuilt as a broad tree-lined boulevard, intended to be the pedestrian-friendly commercial spine of the new neighbourhood.
