On the 27th of the month, U.S. President Trump declared that the United States would immediately cease all trade negotiations with Canada. This decision stems from Canada's introduction of a digital services tax. Furthermore, Trump announced plans to impose new tariff measures against Canada within the coming week. The President accused Canada of maintaining high dairy tariffs against American farmers for several years and now introducing a digital services tax on American technology companies, terming it a direct affront to the United States. This sudden action promptly stirred market apprehensions regarding U.S.-Canada trade relations, causing a sharp and temporary surge in the USD/CAD exchange rate.
