Located in Southern Ontario on the northwestern shore of Lake Ontario, Toronto is situated on a broad sloping plateau intersected by an extensive network of rivers, deep ravines, and urban forest. Toronto is a densely populated region surrounding the western end of Lake Ontario that is home to 8.7 million people, or around 26% of the entire population of Canada. The demographics of Toronto make it one of the world's most diverse cities, with about 50% of residents having been born in a country other than Canada, and over 200 distinct ethnic origins represented among its inhabitants. The vastly international population of the city reflects its current and historical role as an important destination for immigrants to Canada. While English is the primary language spoken by the majority of Torontonians, there are over 160 different languages spoken in the city.
