Spanning the border from Minnesota into the Canadian provinces of Ontario and Manitoba, Lake of the Woods is an enormous body of water over 68 miles long, 59 miles wide, with 25,000 miles of shoreline-the world's longest lake shoreline.
All except Lake Michigan. Shared by Canada and the US: Lake Huron, Lake Ontario, Lake Erie, Lake Superior. Lake Ontario, Lake Erie, Lake Huron, and Lake Superior are all part of Canada as well as the United States. The southernmost point in Canada is Pelee Island in the western basin of Lake Erie. Near by Point Pelee is the southern most point on the Canadian mainland. In 2008, the 8 Great Lakes States, and Ontario adopted the Great Lakes compact. This was ratified by the US congress and restricts the uses of Great Lakes waters. The concern was the water would be exported to develop more arid regions rather than being used for the benefit of the region.
