I came across this excellent article on www.mapleleafweb.com. It's a little bit of us/them 101.
[Ed. Note: When reading, it may be useful to some readers to bear in mind that Mapleleafweb is quite business-oriented/right-wing. For instance, in this article they quote and refer to a C.D. Howe institute report and say things like "It is difficult to argue against such a constructive concept as free trade..." etc.]
