Spawned out of post-glacial alluvial deposits and bluffs, the area was populated at different times by Iroquois and later Wyandot (Huron) peoples. The settlement by Europeans started with the French building a seldom occupied fort near today's Exhibition grounds in the mid-1700s, then grew out of a backwoods English trading post established as York in 1793 (reverting to the current name Toronto in 1834). Later in the 19th century, it grew to become the cultural and economic focus of Canada. Owing largely to the country's liberal immigration policies starting in the 1960s, and the region's strong economy, Toronto has, in recent decades, been transformed into one of the most culturally and ethnically diverse cities in the world. More than 80 ethnic communities are represented, and over half of the city's residents were born outside Canada. (Toronto Wikitravel)
