Not sure I have the extent of it but it sounds a lot like Trump wanted Carney to ease Canadian French language rules (and enrage Quebec) so the Ellisons could save a buck on localization
Let’s put it this way: The Simpsons are dubbed in a French (France) version and in a separate French (Québec) version.
Because if Homer were Parisian it would sound utterly ridiculous.
It's much older and heavy on the regional slang than modern Parisian. pronunciation is less crisp etc.
it's very pretty to listen to, I think it's prettier than Parisian but i could be biased.
More accurate to say that Québécois French has vocabulary differences rather than to call it regional slang. There are archaic words and words that simply evolved differently. The accent is generally more nasal. I agree that is heavy and less crisp.
