Toronto is the largest city in Canada and the provincial capital of Ontario as well as the fourth most populated city in North America. It is positioned in Southern Ontario on the northwestern shore of Lake Ontario. Its multi-ethnic and international populace reflects its role as an essential destination for immigrants to Canada. Toronto is one of the most diverse cities in the world by proportion of non-native-born residents, with almost half of the inhabitants born outside of Canada.
Real estate in Toronto is based on the fact that the city is interconnected by three rivers and copious tributaries. The Humber River is in the west end and the Don River east of downtown at opposite ends of the Toronto Harbour, and the Rouge River at the city's eastern limits.
The harbour was physically created by sediment build-up from lake streams that shaped the Toronto Islands. The countless creeks and rivers bisecting from north toward the lake formed large tracts of thickly forested ravines, and offer ideal sites for parks and recreational trails.
In spite of its deep ravines, Toronto is not astonishingly hilly, but does augment in elevation steadily away from the lake. There are sporadic hilly sections; especially in midtown Toronto where number of rolling hills exists. Lake Ontario is intermittently visible from the points of these ridges as far north as Eglinton Avenue.
Toronto edifices vary in style and age with numerous buildings dating back to the mid-19th century, while other well-known structures were just recently built in the first decade of the 21st century. The CN Tower defines the Toronto skyline and is a telecommunications and tourist hub.
