My flatmate is French, and spent a year in Canada. She agrees that Canadians can't actually speak French. Apparently their accent is atrocious, and as this article demonstrates, they have a habit of inventing new words that even L'Académie française thinks are pointless.
Mind you, dare I suggest that the French can be a trifle picky over other people's French speaking? After all, we may not like the way the Americans butcher our language, but at least we don't pretend we can't understand them.
