It happens in both languages. Sometimes, in staff meetings outside Quebec, for example, they say “hello/bonjour” and “agenda/ordre du jour”, but the meeting is held in English. There could be a similar situation in Quebec. A Quebec official told me that working in French was not a problem for them, except when they were dealing with federal staff in Ottawa. It would be the same situation: The presentation would begin with “hello/bonjour”, but the rest would take place in only one language.
