US Imposes 50 Percent Tariffs on $20 Billion of Canadian Goods After Trade Talks Collapse

The United States began collecting an additional 50 percent tariff on roughly $20 billion worth of Canadian imports on Saturday after last-ditch negotiations failed to resolve the latest dispute between the two countries.

Canadian Prime Minister Mark Carney said Canada will respond with dollar-for-dollar retaliatory tariffs that take effect the Tuesday after Labor Day. The Canadian measures will target steel, dairy, appliances, agricultural equipment, pulp and paper and electronics.

US Trade Representative Jamieson Greer said Washington had offered to reduce tariffs on steel, autos and lumber but Canada rejected the terms. "We've said enough," Greer stated, adding that the goal is to protect American workers and supply chains.

The new duties stem from three presidential proclamations issued on July 20 under Section 338 of the Tariff Act of 1930. They address what the White House described as Canadian discrimination against US motor vehicles, dairy products and alcoholic beverages.

The tariffs stack on top of existing duties and apply regardless of USMCA origin. Covered goods include selected alcoholic beverages, dairy ingredients, agricultural and food products, chemicals, plastics, wood and paper products, textiles, furniture, machinery, electronics, toys and sporting goods such as hockey sticks.

Energy, potash, certain fish, critical minerals and products already under Section 232 measures are excluded. The duties took effect at 12:01 a.m. Eastern Time on August 19 for some categories and expanded with the latest action.

On an annualized basis the measures affect about $24 billion in Canadian trade, or roughly 5.5 percent of total Canadian imports into the United States, according to analysis based on May 2026 trade data.

Carney blamed Washington for the breakdown, saying last-minute changes in the US proposed terms were unfair and called into question the reliability of any deal. Trump administration officials countered that Canada had maintained 25 percent tariffs on certain US vehicles and other barriers for more than a year.

The escalation deepens a trade conflict that has already raised prices for consumers and producers on both sides of the border. Wine, furniture and hockey sticks are among the Canadian products now facing the 50 percent duty.

Further measures could follow, US trade officials indicated. The absence of a statutory expiration date means the Section 338 tariffs remain in force until explicitly modified or revoked.

Business groups on both sides have warned of disrupted supply chains and higher costs for manufacturers that rely on cross-border components. The next phase will depend on whether the retaliatory Canadian tariffs prompt renewed talks or further escalation.
