History

Historical Context

In March 2002 President George W. Bush imposed 30% steel tariffs, exempting NAFTA partners Canada and Mexico, sparking WTO disputes. The WTO ruled against the measures on 11 November 2003 and authorized over $2 billion in sanctions, forcing the tariffs off by 4 December 2003. That precedent frames Canada’s 8 September 2026 retaliation on $20 billion of U.S. goods, echoing the earlier clash.
