Hamilton is a port city in the Canadian province of Ontario. Hamilton has a population of 569,353, and its census metropolitan area, which includes Burlington and Grimsby, has a population of 785,184. The city is approximately 45 kilometres (28 mi) southwest of Toronto in the Greater Toronto and Hamilton Area (GTHA). 

Conceived by George Hamilton when he purchased the Durand farm shortly after the War of 1812, the town of Hamilton became 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 current boundaries of Hamilton were created through the amalgamation of the original city with other municipalities of the Regional Municipality of Hamilton–Wentworth. Residents of the city are known as Hamiltonians. 

Traditionally, the local economy has been led by the steel and heavy manufacturing industries. During the 2010s, a shift toward the service sector occurred, such as health and sciences. Hamilton is home to the Royal Botanical Gardens, the Canadian Warplane Heritage Museum, the Bruce Trail, McMaster University, Mohawk College, and Redeemer University. McMaster University is ranked 4th in Canada and 69th in the world by Times Higher Education Rankings 2021. 

Hamilton is in Southern Ontario on the western end of the Niagara Peninsula and wraps around the westernmost part of Lake Ontario; most of the city, including the downtown section, is on the south shore. Hamilton is in the geographic centre of the Golden Horseshoe. Its major physical features are Hamilton Harbour, marking the northern limit of the city, and the Niagara Escarpment running through the middle of the city across its entire breadth, bisecting the city into “upper” and “lower” parts. The maximum high point is 250m  above the level of Lake Ontario.
