US Canada trade war escalates

The escalation of tariffs between the US and Canada is expected to raise prices for consumers and disrupt supply chains in both countries, affecting industries such as automotive, steel, and agriculture. The uncertainty surrounding the United States–Mexico–Canada Agreement review and the potential for prolonged trade conflict could weigh on business investment and economic growth in North America.
The United States and Canada fell deeper into a trade war after negotiations in Washington collapsed on Friday. The US imposed 50% tariffs on $20 billion worth of Canadian goods, invoking Section 338 of the Smoot–Hawley Tariff Act, a rarely used Depression-era provision. Canada responded by setting September 8 as the start of retaliatory penalties, targeting industries including steel, dairy, appliances, agricultural equipment, pulp and paper, and electronics. Prime Minister Mark Carney accused Washington of using 'economic integration as a weapon' and called the demands 'unacceptable.' US Trade Representative Jamieson Greer said the US was compelled to act after a year of Canadian retaliation. The breakdown casts doubt on the future of the United States–Mexico–Canada Agreement trade agreement, as talks with Canada have not begun. The political impact is expected to be significant, with a petition to expel US Ambassador Wopke Hoekstra gaining nearly 248,000 signatures. Both sides face pressure to find an off-ramp, but no further talks are planned.
