U.S. 50% Tariffs on $28B of Canadian Goods Take Effect After Trade Talks Collapse

THREAT · Export Alberta · Trade Policy

The United States imposed 50% tariffs on roughly $28 billion of Canadian goods at 12:01 a.m. ET on Saturday, August 23, after trade talks between Ottawa and Washington collapsed. The measures target steel, dairy products, appliances, agricultural machinery, paper and electronics — about 5% of Canadian exports to the U.S., according to Al Jazeera. One trade expert warned tariffs at this level would “effectively price hundreds of Canadian goods out of the US market.”

Prime Minister Mark Carney called the U.S. terms “uneconomic, unfair” and said Canada “cannot accept what they’ve offered.” President Trump has separately threatened further increases on vehicles, auto parts and steel, keeping the escalation risk live even for categories not yet named.

What it means: If you export in an affected category, a 50% duty is not a margin problem you can absorb — it is a market-access problem. The immediate work is confirming your HS codes against the tariff list, talking to U.S. customers before they act unilaterally, and accelerating any diversification plans into interprovincial, European or Indo-Pacific channels you have been deferring.
