May I point out that signs on French roads say "STOP".  Respectfully suggest that Quebec stop with the "ARRÊT" signs.  The French will tell you that it is "lousy" French.  No language, except Mandarin Chinese" is "pure".

Montreal is so bi-lingual that hearing two languages in a sentence is almost a given sometimes.  Had a flat tire in the Eastern Townships, oops I mean Les Cantons-de-l’Est, and found one of the last English speaking  farms in the area.  My Swiss/French language skills are sometimes useless.
