Canadian Prime Minister Justin Trudeau announced his resignation after facing an increasing loss of support both within his party and in the country. Now Trudeau’s Liberal Party must find a new leader while dealing with U.S. President-elect Donald Trump’s threats to impose steep tariffs on Canadian goods and with Canada's election just months away. Trudeau plans to stay on as prime minister until a new leader of the Liberal Party is chosen. The political upheaval comes at a difficult moment for Canada. Trump keeps calling Canada the 51st state and has threatened to impose 25% tariffs on all Canadian goods.
