US-Canada trade row heats up as auto tariffs loom at 50%

Tensions between the US and Canada deepen after talks collapse, with President Trump threatening to raise tariffs on Canadian-made autos, trucks, and parts from 25% to 50% starting January 1. Canada pledges reciprocal measures and says talks could resume only with a "right attitude." The dispute jeopardizes the USMCA and risks broader economic disruption, prompting Ottawa to boost diversification and infrastructure like icebreakers while firms brace for impact.
