Canada and Mexico on Friday sought to show U.S. President Donald Trump's administration evidence of progress in curbing the flow of fentanyl opioids into the U.S. ahead of a March 4 deadline for punishing 25% tariffs on their goods imports.

Canadian Prime Minister Justin Trudeau said Thursday that Canada will have an immediate and strong response to tariffs that President Trump says will start on Tuesday.

President Trump declared Thursday that tariffs on goods from Canada and Mexico will go into effect next week, arguing that both countries haven’t done enough to combat the flow of drugs into the US. Mexico and Canada dodged the imposition of 25% tariffs earlier this month,
