Canadian Prime Minister Mark Carney condemned the U.S. for imposing 50% tariffs on $20 billion of Canadian goods, describing it as an 'attack' that escalates the ongoing trade war.13

The tariffs, effective early Sunday, bypass USMCA exemptions, raising concerns about the future of the trade agreement.

Carney stated, “In short, they asked too much and they offered too little. You’re at war when you get attacked. We got attacked,” referring to the Trump administration's actions.

The tariffs apply to various products, including dairy, wine, and furniture, and are enacted under Section 338 of the Tariff Act of 1930.67

Carney, who has previously served as Governor of the Bank of Canada and the Bank of England, emphasized that Canada would not passively accept these measures, stating, “Canada has what the world wants. And we will not allow any nation to determine our future.”

The U.S. has also indicated it would not sign a 16-year renewal of the USMCA unless Canada and Mexico made concessions, further complicating the trade landscape.2

This direct override of traditional protections, combined with stalled negotiations, places the future of the USMCA in serious doubt.

Key Insight
“The new levies apply to dairy, wine, and furniture, and bypass USMCA exemptions, putting the pact's future in doubt. Carney, a former Bank of Canada and Bank of England governor, vowed retaliation, saying 'We will not allow any nation to determine our future.'”
