Canada's Counter-Tariffs Take Effect As Trump Targets Bombardier And Midterm Battlegrounds

Canada's retaliatory tariffs on U.S. goods took effect at 12:01 a.m. Tuesday - raising duties of 15%, 25%, and 50% on hundreds of American products after last month's collapse of bilateral talks. Ottawa says the package matches the United States "dollar for dollar, rate for rate." Finance Canada values the covered U.S. imports at $27.6 billion; some U.S. accounts put the figure nearer $20 billion. Either way, it is a small share of total two-way trade - and a large share of the political risk.

The list is drawn from goods already hit by U.S. Section 338 and Section 232 tariffs. Section 338, a long-dormant provision of the Tariff Act of 1930, had not previously been used by a president to impose duties; Trump invoked it in July to levy 50% on selected Canadian goods after talks failed, and those U.S. duties took effect August 22. Canada's matching rates now apply as follows: 50% on most steel and aluminum products (up from an earlier 25% Canadian counter-duty), plus furniture and clothing; 25% on appliances, dairy including cheese, and some metal derivatives; 15% on selected electronics, tools, and machinery. Goods already in transit when the rules took effect are exempt. The surtaxes apply to U.S.-origin goods under Canadian marking rules, not merely to shipments that happen to cross the border.

Seafood and fish were on Ottawa's original list at 25% but were pulled on August 27 after warnings from Canada's Atlantic processors and Maine's lobster i
