That's fascinating, so they pick up that it's Québécois French and then decide to do that? Is there something in particular that makes them look down on people from Quebec or Québécois French?
I lived in France for a while, and didn't experience very many people wanting to speak English with me since my French was pretty good, though I have a very thick anglophone accent (I'm American, but they always assumed I was British for some reason). Usually my experience has been that most French people don't want to speak anything other than French unless they are purposefully wanting to practice their English with someone (and not speaking any French and trying to beg people to communicate with you in English is a great way to make people instantly annoyed with you). The fact they would do the opposite with people that speak a slightly different variant of French is really surprising.
I don't know anything about the Canadian constitution, but I would find it surprising if this passed judicial review, forcing doctors to communicate with patients in a language they don't know is asking for terrible medical outcomes. Potentially having a dead patient because they couldn't effectively communicate with them (like a drug allergy for example) to preserve cultural purity does not seem "reasonable" nor "can be justified in a free and democratic society", according to the Canadian Charter of Rights and Freedoms. However, with how much other democratic norms and rights are backsliding all over the place it also wouldn't be surprising if this was upheld somehow.
