I know of Americans & school groups who enjoy visiting Quebec to practice French without needing a TATL plane ticket or passport.

Without a few people making a fuss, public services/airlines will keep making cost saving decisions that stretch language requirements.

​​​​​It seems telling that having stayed in chain (Hyatt/Marriott) properties worldwide (75 countries), the only place where the single front desk agent could not give proper basic checkin assistance in English? YQB. This year, at a brand new Marriott.

I'd imagine most advocates and those who protest to gain media attention are tired of watching corporations save $ by lowering their bilingual requirement to bare minimum.

Jazz & AC Express agents can play pre recorded French or have a script on a notecard to 'read' in French. The hotel I mentioned offered to use Google Translate to English. I think I read (but have not experienced) that AC's LCC competition requested and received an exemption on the bilingual service requirement.

Sure, AC could only schedule their Quebec service, and specifically J cabin crew with bilingual staff. But doing that in their more profitable & exclusive cabins? Sheesh, they'd need to raise prices
