Ontario (pronounced /ɒnˈtɛəri.oʊ/) is a province located in east-central Canada, the largest by population and second largest, after Quebec, in total area. (Nunavut and the Northwest Territories are larger but are not provinces.) Ontario is bordered by the provinces of Manitoba to the west and Quebec to the east, and the U.S. states (from west to east) of Minnesota, Michigan, Ohio and Pennsylvania (both across Lake Erie), and New York to the south and east. Most of Ontario's borders with the United States are natural, starting at the Lake of the Woods and continuing through four of the Great Lakes: Superior, Huron (which includes Georgian Bay), Erie, and Ontario, then along the Saint Lawrence River near Cornwall. Ontario is the only Canadian province that borders the Great Lakes. For analytical purposes Ontario is often broken into two regions, Northern Ontario, and Southern Ontario. |
