Donald Trump is increasing pressure on Canada by threatening to use an obscure Great Depression-era provision of U.S. trade law to impose new tariffs. Multiple outlets describe the move as relying on Section 338 of the Tariff Act of 1930. They note that Trump’s actions come with uncertainty about what limits apply to the president’s tariff authority and whether any “guardrails” exist to constrain its use.
According to the accounts provided, Trump signs orders directing the use of Section 338, a legal mechanism that can be used to adjust tariffs under specified circumstances tied to trade and economic conditions. The articles frame the potential outcome as a risk of escalation in trade relations: new tariffs could prompt retaliatory measures and contribute to a broader negative cycle affecting both countries.
While the sources differ in emphasis, they largely agree on the central points: Trump is invoking a decades-old tariff tool, the immediate target is Canada, and the legal and political constraints on the approach are unclear. The reporting highlights the possibility of significant downstream impacts for bilateral trade as the policy threat develops.
