U.S. President Donald Trump signed an executive order on Thursday increasing tariffs on Canadian goods to 35% from 25%, the White House said.

The Canadian prime minister said he was "disappointed" by President Donald Trump's move to increase certain tariffs.

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.
