U.S. President Donald Trump announced new 35% tariffs on Canadian imports effective August 1, citing Ottawa’s retaliatory duties and the fentanyl crisis.
“Instead of working with us, Canada responded with tariffs,” Trump wrote in a letter to Canadian Prime Minister Mark Carney on Truth Social, adding he might reconsider if Canada cooperates to curb fentanyl trafficking.
Carney replied on X, highlighting Canada’s progress in tackling fentanyl and pledging continued collaboration with Washington.
The 35% tariff is in addition to existing duties, including 50% on steel and aluminum, 25% on autos, and a 50% levy on copper starting in August. Other Canadian goods already face a 25% tariff over fentanyl concerns, while energy imports remain subject to a 10% rate.
“If Canada raises its tariffs, we will add the same percentage to our 35% duty,” Trump warned, threatening further increases if transshipments are used to evade measures.
He also pointed to broader trade imbalances: “Canada has tariff and non-tariff barriers causing unsustainable trade deficits that threaten our economy and national security.”
Separately, Trump told NBC he plans to raise general tariffs on most trading partners to 15–20%.
The announcement came after both nations agreed to resume trade talks and work toward a deal by July 21. Ottawa had suspended its digital services tax on U.S. firms on June 29 to reopen negotiations.
