U.S. President Donald Trump on Thursday signed an executive order increasing tariffs on Canadian goods to 35% from 25% on all products not covered by the U.S.-Mexico-Canada trade agreement, the White House said.

Trump has justified tariffs on goods from Canada, the top U.S. export market, by accusing it of failing to stop the cross-border flow of fentanyl, even though U.S. government data shows Canada accounts for only 1% of the fentanyl that enters the United States.

Trump’s tariff hike still hits goods that are not covered by the USMCA. The Bank of Canada forecast this week that up to 95 percent of Canadian exports could qualify for exemptions under that agreement. Meanwhile, the share of Canadian companies claiming tariff exemptions has soared.
