Actually that's not surprising ...Quebec French derives from 400 years ago and France is Parisian French and quite different I am told.
I addition there seems to be an ingrained bias to French Canadians in France.
I was flying sailplane with an exPat Quebecer who had decided to emigrate to the motherland 8 years earlier. Gave up his Canadian passport, the whole nine yards.
Was completely miserable and so glad to talk to me. They had made no friends and he said the nearby families were so insular and had feuds going back hundreds of years.
Now this was rural southern France which is world's away from Paris.
Driving in France with family somehow despite having two kids with French classes plus partner with uni-level French ....not one of them would tackle asking for directions.
My French being derived from cereal boxes and ....chaos ensued. Pre Google days.
We found that if we at least tried French, often the citizens would take pity and switch to English.
