axel53: Mr. Trudeau may have been playing into media coverage when he answered English-speaking questioners in French but it's probably more complicated than that. My bilingual French-Canadian grandfather used to assert that questions should be answered in the language in which they're raised but he also tended to switch to accommodate the language most broadly spoken by those in the room. He routinely spoke to his numerous siblings in French but when my mother, who spoke no French, was present he'd switch the conversation to English. I suspect Trudeau was operating on the assumption that the English questioners in Quebec were as or more likely to understand French than were French-speaking attendees in a French province to understand English.
