Canadian sports fans booed the US national anthem during basketball and ice hockey matches in response to President Trump's announcement of steep tariffs on imports from Canada. This unusual behavior was noted at an NBA game in Toronto and NHL matches in Ottawa and Alberta. Canadian Prime Minister Justin Trudeau and Mexico’s President Claudia Sheinbaum announced retaliatory tariffs. Trump's comments suggested Canada should become a US state, which Trudeau countered by asserting Canada's position.
