Canada's countertariffs on $27.6 billion of U.S. goods, effective Sept. 8, are a direct response to President Trump's 50% tariffs.

Dan Ciuriak, an economist, noted that escalation can be appropriate under specific conditions, but warned, “We can’t treat these grievances credibly.”

Wolfgang Alschner, a law professor, emphasized that the U.S. holds a stronger position, stating, “The U.S. is always going to be in a position to hurt us more.”3

The countertariffs aim to create alternative supply lines for Canada, as “it’s a huge effort for the Canadian economy to create supply lines don’t go through the U.S.”

Gitane De Silva cautioned that retaliation may not yield positive results, asserting, “Retaliating is unlikely to get Trump to change his behaviour toward Canada for the better.”45

Experts agree that while countries seek economic gains from trade, “there’s no guarantee with this administration.”2

The situation remains precarious, with potential for further escalation in tariffs, impacting both economies significantly.

Key Insight
“Dan Ciuriak of the Centre for International Governance Innovation says escalation works only when the demand is limited and negotiable, while Wolfgang Alschner of the University of Ottawa notes the U.S. can always hurt Canada more. An unnamed source warns retaliation may worsen Trump's behavior, as limited evidence suggests it leads to higher tariffs.”
