You are absolutely correct in that assumption. The overseas travellers do tend to stay longer with us than the U.S. travellers do, but the U.S. travellers do return. Not only do they return numerous times, and I can attest to that from direct experience, but they also then encourage visiting friends and family that they must go up to Canada and visit Cape Breton, or P.E.I., or whatever it is.
