Trade standoff: Trump's 50% tariff kicks in; Carney vows 'dollar-for-dollar' response

Trade negotiations between the United States and Canada fell apart after a three-day face-off.

Canada called a halt to discussions, criticizing the US for presenting proposals that were both unfair and detrimental.

In a dramatic move, the US introduced hefty tariffs on Canadian goods, prompting Canada to respond with an equal retaliatory measure.

This failure to reach an agreement casts uncertainty over North American trade relations moving forward.
