US Imposes 50% Tariffs on Canadian Goods, Sparking Escalating Trade War

The trade war between the US and Canada has escalated as 50% tariffs on Canadian goods went into effect over the weekend. The levies will affect about 5% of Canada's annual exports to the US, totaling around $20 billion in goods including hockey sticks, agricultural products, wine, cement, honey, seeds, and select makeup.

Canadian Prime Minister Mark Carney has promised 'dollar for dollar' retaliatory measures starting September 8. Experts warn that steeper tariffs will raise costs for businesses and trickle down to households through higher prices.

The Trump administration used a little-known law from the Great Depression era, Section 338 of the Tariff Act of 1930, to impose the tariffs without an investigation or limit on how long they can stay in place. This move has raised questions about the future of the USMCA trade pact and the precedent it sets for future use of this law.

Tariffs have already contributed to higher inflation, but some researchers at the Federal Reserve Bank of St. Louis noted that the effective tariff rate appeared to have leveled off in recent months after the Supreme Court struck down Trump's most sweeping levies.
