Canada’s retaliatory tariffs on American goods are now in effect, marking the start of duties applied in response to prior U.S. trade actions. The measures apply to specified categories of U.S. products and take effect immediately, according to reporting from both outlets.

The news coverage frames the tariffs as part of a broader trade dispute between the two countries. While both sources agree on the timing—when the retaliatory tariffs begin—details on the specific product lists, the scope of the affected goods, and the rationale emphasized by each outlet can differ. One account focuses on the fact that the tariffs are already underway for importers and the practical impact of the policy shift, while the other emphasizes the formal entry into force of Canada’s retaliation against U.S. measures.

Across the reports, the core point is consistent: Canada has moved from announcement to implementation, with tariffs now being applied to designated American exports, signaling an escalation in the trade dispute and laying the groundwork for further negotiations or responses. The long-term outcome depends on how the dispute develops and whether either side changes course.
