About Hamilton

Hamilton (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 industrialised 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 Royal Botanical Gardens, the Canadian Warplane Heritage Museum, the Bruce Trail, McMaster University and Mohawk College. McMaster University is ranked 4th in Canada and 94th in the world by Times Higher Education Rankings 2015-16 and has a well-known medical school. 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 began playing at the new Tim Hortons Field in 2014, which was built as part of the 2015 Pan American Games.

Possibly because of its diverse environment, numerous TV and film productions have been filmed in Hamilton, regulated by the Hamilton Film and Television Office. A growing arts and culture community garnered media attention in 2006 when the Globe and Mail published an article called "Go West, Young Artist" about Hamilton's growing art scene. The article highlighted local art galleries, recording studios and independent film production.

Climate

Hamilton's climate is humid-continental, characterised by changeable weather patterns. However, its climate is moderate compared with most of Canada. Hamilton's location on an embayment at the southwestern corner of Lake Ontario with an escarpment dividing upper and lower parts of the city results in noticeable disparities in weather over short distances. This is also the case with pollution levels, which depending on localised winds patterns or low clouds can be high in certain areas mostly originating from the city's steel industry mixed with regional vehicle pollution. With a July average of exactly 22.0 °C (71.6 °F), the lower city is located in a pocket of the Dfa climate zone found at the southwestern end of Lake Ontario (between Hamilton and Toronto and eastward into the Niagara Peninsula), while the upper reaches of the city fall into the Dfb climate zone.

The airport's open, rural location and higher altitude (240m vs. 85m ASL downtown) results in lower temperatures, generally windier conditions and higher snowfall amounts than lower, built-up areas of the city. One exception is on early spring afternoons; when colder than air lake temperatures keep shoreline areas significantly cooler, under the presence of an east or north-east onshore flow.

The highest temperature ever recorded in Hamilton was 41.1 °C (106 °F) on 14 July 1868. The coldest temperature ever recorded was -30.6 °C (-23 °F) on 25 January 1884.
