Canada's retaliatory tariffs worth $27.6 billion take effect as trade rift with U.S. deepens

Canada's retaliatory tariffs on a swathe of U.S. goods took effect on Tuesday after trade talks collapsed last month, as relations between Washington and Ottawa continue to sour.

The duties range from 15% to 50% across hundreds of U.S. products worth a total $27.6 billion, including dairy, agricultural equipment, paper, household appliances and electronics. Canadian tariffs on U.S. steel, aluminum and iron products doubled to 50%, while furniture, motorbikes, clothing and some beauty products were among the goods hit with the highest rate.

Canada called the move a "dollar for dollar" response to U.S. levies on its own goods, which have been targeted by Section 338 tariffs . Its Department of Finance said it would protect Canadian workers, producers and manufacturers by allowing them to better compete with U.S. products sold in the domestic market.

Existing Canadian counter-tariffs against the U.S., including 25% on the politically sensitive autos sector , remain in place.

Trade talks between the longstanding allies fell apart at the end of August , with officials on each side blaming one another for the failure to reach a deal and publicly disagreeing over which areas they could not find compromise .

U.S. President Donald Trump on Monday called for a boycott of Canadian airplane manufacturer Bombardier , posting on Truth Social: "NO MORE SELLING BOMBARDIER IN THE UNITED STATES!"

The U.S. exported $333.6 billion worth of goods to Canada, and imported $381.9 billion from its northern neighbor. The pair share trade in many of the same sectors, including energy, vehicles, heavy machinery, aircraft, pharmaceuticals, gems and jewelry, furniture, clothing and a host of foods and drinks.

Economists say that while the impacted goods are a relatively small portion of overall trade, small- to medium-sized businesses and those in the most-impacted sectors face a severe blow.
