Not sure what you mean by that? The part of this comic about Canada is just quoting one of the xkcd comics I linked (and neither me nor the comic I was quoting mentioned Mexico).
My main point isn't anything about moving to Canada (or even about politics), but rather what I said in the title text: that the original comic needed a joke or something, so I just found a couple related comics to quote. I don't really have an opinion one way or the other about moving to Canada.
