New 25% tariffs on Canadian and Mexican goods bound for the U.S. came into effect at midnight on Tuesday morning. U.S. President Donald Trump announced the measure a month ago, but put a pause on implementing it after negotiating with the leaders of the two North American nations. Canadian Prime Minister Justin Trudeau has promised retaliatory tariffs on U.S. goods, and Mexican President Claudia Sheinbaum says she has a plan to respond.
