Very good of you to ask that question (in my opinion), Nightfall. It isn;t that things made foreign are necessarily bad, but more that there isn;t enough attention to "buying American" these days (at least, from those of us in the U.S.).
Yep, the RAT line is made in USA. I could be wrong, but I think Ontario does have a line that they sub-out to overseas manufacturers. I've seen them in an Ontario catalog, I think.
