History

Historical Context

In March 2018 President Donald Trump invoked Section 232 national-security grounds to impose 25 % steel and 10 % aluminum tariffs, hitting Canadian imports that had supplied the United States with the most aluminum from 2013-2016. Canada retaliated on July 1, 2018 with matching duties on 299 U.S. products; both sides lifted the tariffs after a May 2019 deal that cleared the path for the USMCA.
