Canada's Defiant Response Puts Trump's Trade War Strategy at Risk

The trade war between Canada and the United States has escalated, with Canadian Prime Minister Mark Carney facing off against President Donald Trump. The dispute began two years ago when Trump imposed steep tariffs on Canadian goods, citing a nonsensical economic rationale that Krugman described as a 'dominance display.'

The US economy is 12 times larger than Canada's, and the US buys three-quarters of Canada's exports. However, access to crucial imports is more important in trade conflicts, as demonstrated by China's threat to cut off rare earth exports, which would be an existential threat to Western technology industries.

Krugman notes that the US economy is far more dependent on Canadian goods than Americans realize. For example, Canada dominates the supply of lumber with a high strength-to-weight ratio, and US refineries need heavy Canadian crude rather than lighter Permian basin oil.
