US-Canada Trade War Hinges on Sovereignty, Tariffs, Leverage
The United States and Canada are arguing about how they trade with each other.
Donald Trump says Canada has benefited unfairly from access to the US market.
Mark Carney says Canada must protect its workers, economy and independence.
The two countries disagreed about tariffs on cars, metals, farm goods and other products.
The United States says tariffs can protect American industries.
Canada says tariffs can hurt Canadian workers and businesses.
Canada plans to respond with tariffs on some American products.
Canada also buys and sells important goods with many US states, so both countries could feel economic pain.
The disagreement has also made Canada want to build stronger trade relationships with countries besides the United States.
Donald Trump says Canada has taken advantage of the United States, while Mark Carney says Canada is defending its sovereignty.
Washington views tariffs as protection for American workers, while Ottawa says trade disruptions threaten Canadian jobs and businesses.
Negotiations broke down after Canada rejected US demands and sought lower auto, steel and aluminium tariffs.
Canada plans targeted counter-tariffs of 15%, 25% and 50% on $27.6 billion of US imports starting September 8.
The dispute has exposed both US leverage over Canadian exports and Canada’s ability to retaliate through trade, energy and targeted measures.

Leverage and retaliation

Trump argues that the US can obtain Canadian goods elsewhere and that Canada needs access to the American market more than the US needs Canadian products.
