Orillia is a city in Simcoe County between Lake Couchiching and Lake Simcoe. Both lakes are part of the Trent-Severn Waterway. Although it is in Simcoe County, the city is politically independent. It is part of the Huronia region of Central Ontario. It was incorporated as a village in 1867, but the history of what is today the City of Orillia dates back at least several thousand years. Archaeologists have uncovered evidence of fishing by the Huron and Iroquois peoples in the area over 4,000 years ago, and of sites used by Aboriginal peoples for hundreds of years for trading, hunting, and fishing.
