Hamilton ( /ˈhæməltən/; 2011 population 519,949; UA population 670,580; CMA population 721,053) 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, 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 the amalgamation of the former city and the other constituent lower-tier municipalities of the Regional Municipality of Hamilton-Wentworth with the upper-tier regional government. Residents of the old 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.

Hamilton is home to the shared Royal Botanical Gardens, the Canadian Warplane Heritage Museum, the Bruce Trail, McMaster University and Mohawk College. The Canadian Football Hall of Fame can be found downtown right beside Hamilton City Hall and across town to the east, the Canadian Football League's Hamilton Tiger-Cats play at Ivor Wynne Stadium.

Ontario /ɒnˈtɛərioʊ/ is one of the provinces of Canada, located in east-central Canada. It is Canada's most populous province or territory and fourth largest in total area. It is home to the nation's most populous city, Toronto, and the nation's capital, Ottawa.

Ontario is bordered by the province of Manitoba to the west, Hudson Bay to the north, Quebec to the east, and to the south by the U.S. states of Minnesota, Michigan (portions to the west), New York (portions to the east), Ohio and Pennsylvania. All but a small part of Ontario's 2,700 km (1,677 mi) border with the United States follow inland waterways: from the west at Lake of the Woods, eastward along the major rivers and lakes of the Great Lakes/St. Lawrence River drainage system. These are the Rainy River, the Pigeon River, Lake Superior, the St. Mary's River, Lake Huron, the St. Clair River, Lake St. Clair, the Detroit River, Lake Erie, the Niagara River, Lake Ontario, and along the St. Lawrence River from Kingston, Ontario to the Quebec boundary just east of Cornwall, Ontario.
