Truck tariff dispute derails US-Canada trade agreement

Negotiations between the US and Canada broke down Friday after Canada insisted on extending tariff relief to medium- and heavy-duty vehicles, a request the US rejected. The collapse led to new US tariffs on roughly $20 billion in Canadian goods, with Canada announcing matching counter-tariffs starting Sept. 8. Both sides blamed each other, with Canadian officials suggesting the US aimed to undermine its auto manufacturing sector.
