The Great Lakes are part of the border between the USA and Canada.
Lakes through which the International Boundary between Canada and the US runs includes, in addition to four of the Great Lakes, Lake of the Woods, Rainy Lake, Lake St Clair, and approximately 40 smaller lakes in the Quetico Park area.
The Great Lakes, which form part of the International Boundary between Canada and the US, contain approximately 20% of the world's fresh water. Traditionally there are five Great Lakes: Superior, Huron, Michigan, Erie and Ontario. Hydrologically, however, there are only four. What we know as Lakes Michigan and Huron constitute just one body of water.

Lake Superior
Partly, yes. However a body of water can also be split by invisible border lines that depict which part of the body of water lies in which state and which lies in the other. This applies in the case of the Great Lakes, where some part of the Great Lakes reside in Canada and others reside in the USA.

Michigan is the only state which is cut in two by one of the Great Lakes. Michigan's upper peninsula is separated from the lower part by lake Michigan.
Ontario. You might make a case for Quebec and some of the Maritime provinces if you include the St. Lawrence Seaway as part of the Great Lakes by virtue of its connection to the Great Lakes [primarily Lake Ontario].
