Thank you.
I think you're dragging in a red herring here. Air Canada hasn't responded from the start. There really seems to be resistance on its part. You don't acknowledge the problem, and that doesn't look good for the future. You say there's one bilingual flight attendant per aircraft, but I'm not sure that's enough. If there are 200 passengers and a flight attendant who isn't bilingual, there will definitely be some problems.
Are you aware that French isn't just one of the two official languages in Quebec; it's the only official and common language.
