Am I misremembering that Americans booing the Canadian anthem was retaliation for Canadians booing the American national anthem? I'm not excusing either but my recollection is Canadians did it first - with that said, I have no clue if it was Toronto. If it was the Americans first what was the trigger? Pretty sure I know what the trigger was if it was Canadians first, but that's a topic for the PPP folks.
