Yeah that's a myth, there's a lot of variation in our language within our own country in the first place, from the Parisians to the Marseillais to those in the Pays de Basque and etc...

But we do love making fun of the french canadian accent. It sounds absolutely hilarious to us. We had a whole puppet tv show based on making fun of french canadians and their accents called Tetes a Claques. The term Tetes a Claques itself means a face which you want to slap.
