Trump Invokes 1930s Great Depression Law for 50% Tariffs on Canada
Tap title to read story
The United States and Canada entered a severe trade war following the Trump administration's invocation of Section 338 of the Tariff Act of 1930. President Donald Trump authorized the executive action to impose tariffs of up to 50 percent on Canadian imports, bypassing judicial rulings that struck down previous penalties. The statute, originating from the Smoot-Hawley legislation, has never been used before. The decision follows a February Supreme Court ruling against earlier federal trade measures. Canadian Prime Minister Mark Carney and Trade Minister Dominic LeBlanc condemned the move from Parliament Hill. The action disrupts integrated cross-border supply chains in agriculture, automotive manufacturing, and lumber. Furthermore, the escalation halts bilateral talks regarding the renewal of the United States-Mexico-Canada Agreement with Ottawa. Federal border agencies are preparing for immediate implementation while no de-escalation timeline has been established by either administration amid growing economic uncertainty.
