Toronto is the capital city of the Canadian province of Ontario. With a recorded population of 2,731,571 in 2016,[14] it is the most populous city in Canada and the fourth most populous city in North America. The city is the anchor of the Golden Horseshoe, an urban agglomeration of 9,245,438 people (as of 2016) surrounding the western end of Lake Ontario,[15] while the Greater Toronto Area (GTA) proper had a 2016 population of 6,417,516. Toronto is an international centre of business, finance, arts, and culture, and is recognized as one of the most multicultural and cosmopolitan cities in the world.[16][17][18]

People have travelled through and inhabited the Toronto area, located on a broad sloping plateau interspersed with rivers, deep ravines, and urban forest, for more than 10,000 years.[19] After the broadly disputed Toronto Purchase, when the Mississauga surrendered the area to the British Crown,[20] the British established the town of York in 1793 and later designated it as the capital of Upper Canada.[21] During the War of 1812, the town was the site of the Battle of York and suffered heavy damage by American troops.[22] York was renamed and incorporated in 1834 as the city of Toronto. It was designated as the capital of the province of Ontario in 1867 during Canadian Confederation.[23] The city proper has since expanded past its original borders through both annexation and amalgamation to its current area of 630.2 km2 (243.3 sq mi).

The diverse population of Toronto reflects its current and historical role as an important destination for immigrants to Canada.[24][25] More than 50 percent of residents belong to a visible minority population group,[26] and over 200 distinct ethnic origins are represented among its inhabitants.[27] While the majority of Torontonians speak English as their primary language, over 160 languages are spoken in the city.[28]

Toronto is a prominent centre for music,[29] theatre,[30] motion picture production,[31] and television production,[32] and is home to the headquarters of Canada’s major national broadcast networks and media outlets.[33] Its varied cultural institutions,[34] which include numerous museums and galleriesfestivals and public events, entertainment districts, national historic sites, and sports activities,[35] attract over 43 million tourists each year.[36][37] Toronto is known for its many skyscrapers and high-rise buildings,[38] in particular the tallest free-standing structure in the Western Hemisphere, the CN Tower.[39]
