What actually happened
The United States’ 50% tariffs on a range of Canadian goods took effect after last-minute trade talks collapsed. Canada’s Prime Minister Mark Carney suspended negotiations, saying Washington’s new demands were uneconomic, unfair and inconsistent with Canadian sovereignty; Ottawa pledged dollar-for-dollar counter-tariffs beginning the Tuesday after Labour Day. The immediate goods fight matters, but the larger story is the rupture of an assumption: that the world’s most integrated bilateral trading relationship could rely on stable rules.
