The city of Hamilton, Ont, is situated at the west end of Lake ONTARIO, on Burlington Bay, 68 km southwest of Toronto and 66 km west of NIAGARA FALLS and the American border. As part of the reorganization of municipal governments in Ontario, the boundaries of the city were enlarged in 2001 to include much of the surrounding suburban and rural area, including the former towns of ANCASTER, DUNDAS, FLAMBOROUGH and STONEY CREEK and the former township of Glanbrook. The city is Canada's largest steel producer and a major Great Lakes port.
