US-Canada trade talks collapse as 50% tariffs trigger dollar-for-dollar retaliation

Trade negotiations between the United States and Canada broke down after three days of failed discussions. Canada halted the talks, accusing the US of putting forward proposals it deemed unfair and harmful to Canadian interests. The US then imposed steep 50% tariffs on Canadian goods, prompting Ottawa to announce an equal retaliatory response. The breakdown marks a significant escalation in trade tensions between the two neighboring countries. The standoff raises serious concerns about the stability of North American trade relations going forward.
