Trudeau's visit comes as Trump has threatened to impose a 25 percent tariff on goods from Canada and Mexico unless the countries curb what he described as the flow of drugs and migrants across their borders. Trump made the remarks on Monday, warning that imposing such tariffs would be among his first executive orders.

In conversations with Trump, Trudeau has been keen to point out that the number of illegal migrants coming into the United States from Canada is far lower than Mexico, while his top officials have loudly voiced their cooperation with U.S. authorities on the fentanyl crisis.
