• The 35% duty will apply to most Canadian imports not already subject to security-driven levies on steel, aluminum or vehicles under emergency economic powers.
• This increase builds on an existing 25% fentanyl-related sanction tariff by adding 10 percentage points to pressure Canada over opioid controls.
• Trump published a letter to Prime Minister Trudeau on social media urging tougher action on synthetic opioid trafficking and offering to reconsider the duties if Canada cooperates.
• The administration has issued formal letters to 23 countries outlining similar tariff measures, with major partners such as the EU, Mexico, India and Taiwan still unnotified.
