Well, this is what Google says Canadian bacon is.
"Both Canadian bacon and ham come from pork and might look the same depending on the forms they take, but there are key differences. ... Cut: The main difference between the two is that Canadian-style bacon comes from the back of the pig, and is a loin cut. Ham comes from the back legs or butt."
Might be like not having "American" cheese in Canada. My kids were highly amused when we ate at Dennys and they ordered a grilled cheese sandwich and the menu said it was made with"Canadian" cheese. LOL>
