Ontario Peninsula

The Ontario Peninsula is the southernmost part of the province of Ontario and of Canada as a whole. It is bounded by Lake Huron on the west, Lake Ontario on the east, and Lake Erie on the south. At its tip, it is separated from Michigan by the Detroit and St. Clair rivers, as well as Lake St. Clair. The peninsula also includes the Bruce and Niagara peninsulas, one projecting into Lake Huron and the other projecting towards New York, from which it is separated by the Niagara River.

The corner of the peninsula that lies on Lake Ontario is known as the Golden Horseshoe and forms Canada's largest population centre. Other large cities include London and Windsor.
