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.

President Trump says he'll impose tariffs on Mexico and Canada on Tuesday. Mexico is working hard to persuade Trump to hold off on the threat.

Tariffs have become President Donald Trump's favored economic move, and they're set to go into effect against Canada and Mexico next week.

President Donald Trump said Thursday that 25% tariffs on goods imported from Canada and Mexico would go into effect Tuesday, alongside yet another 10% layer of duties on China following one that came into effect earlier this month.

President Donald Trump said Thursday tariffs of 25% on Mexican and Canadian goods are set to take effect on March 4, while also threatening to impose an additional 10% on Chinese imports on the same date.

President Donald Trump says he plans to impose tariffs on Canada and Mexico starting next Tuesday, in addition to doubling the 10% universal tariff charged on imports from China.

President Donald Trump pledged Thursday to enforce his planned 25 percent tariffs on Canada and Mexico starting March 4, after both were put on pause earlier this month.

President Donald Trump says his tariffs on Canada and Mexico are starting next month. The comment Monday indicates the end of a monthlong suspension on planned import taxes that could potentially hurt growth and worsen inflation.
