A timeline of Donald Trump's trade war with Canada
Trump raises duties on Canadian goods to 35%, while Ottawa answers with retaliatory tariffs and provinces pull U.S. alcohol from shelves.
- On July 31, President Donald Trump signed an executive order raising U.S. tariffs on Canadian imports to 35 per cent from 25 per cent, exempting CUSMA-compliant goods from the new rates.
- Earlier measures invoked the International Emergency Economic Powers Act to impose blanket 25 per cent tariffs on Canadian goods; the Supreme Court later ruled this use unlawful, prompting the new executive order.
- Prime Minister Mark Carney's government enacted 25 per cent retaliatory tariffs on $29.8 billion in U.S. goods, targeting steel, aluminum, computers, and sports equipment. Provincial distributors removed American alcohol from shelves in response.
- Vermont Senator Peter Welch reported tourism declined about 40 per cent last month at a Senate hearing, while the Lumber Trade Council noted softwood lumber import taxes now exceed 45 per cent.
- United States Trade Representative Jamieson Greer stated the U.S. would not renew the CUSMA trade pact "in its current form," even as Canada plans to drop retaliatory tariffs to match U.S. exemptions effective Sept. 1.
