Hamilton is a city in Ontario. Population-wise, it is Ontario's third-largest city, with a population over 500,000. Hamilton is located at the head of Lake Ontario.
After the War of 1812, Captain George Hamilton moved to the area that is now Hamilton, and laid out a town site in 1816. Hamilton became a town in 1833 and a city in 1846.
On January 1, 2001, the city of Hamilton was amalgamated with the neighbouring towns of Dundas, Ancaster, Flamborough, and Stoney Creek and the township of Glanbrook, forming a "megacity" with around 500,000 people over an area of over 1,000 square kilometres.
Traditionally, Hamilton's economy has been based around manufacturing. Two of Canada's largest steel producers, Dofasco and Stelco, are based there.
