Toronto's Old City Hall was home to its city council from 1899 to 1966 and remains one of the city's most prominent structures. The building is located at the corner of Queen and Bay Streets, across Bay Street from Nathan Phillips Square and the new City Hall in the centre of downtown Toronto. The heritage landmark has a distinctive clock tower which heads the length of Bay Street from Front Street to Queen Street as a terminating vista.

Old City Hall was designated a National Historic Site of Canada in 1984.
