Hamilton ( ) (2006 population 504,559; UA population 647,634; CMA population 692,911) is a port city in the Canadian province of Ontario. Conceived by George Hamilton when he purchased the Durand farm shortly after the War of 1812, the town of Hamilton has become the centre of a densely populated and industrialized region at the west end of Lake Ontario known as the Golden Horseshoe. On January 1 2001 the new City of Hamilton was formed through amalgamation of the former City with the constituent towns of the Hamilton-Wentworth Regional Municipality. Residents of the city are known as Hamiltonians. Since 1981, the metropolitan area has been listed as the ninth largest in Canada and the third largest in Ontario.

Traditionally, the local economy has been led by the steel and heavy manufacturing industries. Within the last decade, there has been a shift towards the service sector, particularly health sciences. The Hamilton Health Sciences corporation employs nearly 10,000 staff and serves approximately 2.2 million people in the region.

Hamilton is home to the Royal Botanical Gardens, the Canadian Warplane Heritage Museum, the Bruce Trail, McMaster University and several colleges. The Canadian Football League's Hamilton Tiger-Cats play at Ivor Wynne Stadium, close to the Canadian Football Hall of Fame. Partly because of its diverse locations, numerous TV and film productions have been filmed in Hamilton regulated by the Hamilton Film Liaison Office. A growing arts and culture sector had garnered media attention in a 2006 Globe and Mail news article, entitled "Go West, Young Artist," focused on the growing art scene in Hamilton. The article highlighted local art galleries, recording studios and independent film production.
