What I did with lake superior is used the canvec data to build the big lake superior object. The multi-polygon become natural=water. then converted the entire line that was the shore to natural=coastline and connect it to the existing coastline out side the object. That way if you import the data into a GPS the lake object for canada shows up, but the is an existing coastline as well (which the US side uses a coastline)
Personally I like the idea of having the lake object that way you can pull it as one object.
