Four of the five Great Lakes border Canada: Lake Erie, Lake Huron, Lake Ontario and Lake Superior. Lake Michigan is the only one that does not border Canada; it is located completely within U.S. borders.
Lake Superior is the largest freshwater lake in the world. It's 31,820 square miles (82,414 square km), 350 miles (563 km) long and 160 miles (257 km) at its widest part. Lake Superior is bordered on the west by Minnesota, on the north and east by Ontario, Canada, and on the south by Michigan and Wisconsin.
