President-elect Donald Trump's pledge to impose tariffs on Canada, Mexico, and China has drawn strong international criticism, with officials warning of economic consequences for all four countries. Trump announced plans for 25% tariffs on goods from Canada and Mexico and 10% on Chinese imports, citing efforts to address illegal immigration and drug trafficking. Mexican President Claudia Sheinbaum warned that Mexico would retaliate against Trump's tariffs by imposing taxes on U.S. imports, endangering shared businesses. Trudeau urged lawmakers to approach U.S. tariff threats calmly and collaboratively, while provincial leaders proposed retaliatory tariffs emphasizing Canada's vital exports like oil, electricity, and critical minerals.
