That's a common stereotype of Québécois French, but I think it's more accurate to say that, just like for pretty much all widely spoken languages, there was a lot more regional variation in the French-speaking world a few hundred years ago, but it's been consolidating over time, and different places happened to consolidate differently.

IOW, Parisian French also retains some primitive features that have largely disappeared from one Canadian region or another. But we don't talk about those as much. I'm guessing because doing so wouldn't jive well with certain stereotypes about Québec being a backwards hinterland.
