Untested in court, Trump’s new tariffs on Canada raise legal questions
The move triggered dollar-for-dollar retaliation from Ottawa and tested a rarely used tariff power that has never been challenged in court.
- On August 21, President Donald Trump invoked Section 338 of the Tariff Act of 1930 to impose a 50% tax on $20 billion worth of Canadian imports, marking the first presidential use of the Depression-era statute.
- The Trump administration cited Section 338 to sanction Canada for alleged discrimination against U.S. dairy, auto, and alcoholic beverage exports; the law is part of the notorious Smoot-Hawley Act, which sat unused since the Great Depression.
- Legal scholars Peter Harrell and Jennifer Hillman argue the administration failed to calculate actual damages from alleged discrimination, while Liberty Justice Center CEO Sara Albrecht suggests newer trade laws likely superseded the obscure statute.
- Dollar-for-Dollar retaliatory tariffs from Ottawa strained relations between the allies, and no plaintiffs have yet filed a formal lawsuit challenging the administration's reliance on the untested legislation.
- Albrecht noted a chance that both countries could resume talks broken off August 21 to reach a compromise, even as the administration continues collecting these import taxes.
