A significant new tariff of 50% on a wide array of Canadian products took effect Saturday, following the failure of last-minute trade negotiations between the United States and Canada. The duties apply to approximately $20 billion worth of Canadian goods, encompassing items such as wine, hockey sticks, and cement, according to officials.

U.S. Trade Representative Jamieson Greer stated that Canada declined to finalize a trade deal under previously agreed-upon terms. "New demands and walk backs of other commitments by Canada have upended the careful balance reached in the past days," Greer told reporters. He added that the U.S. had offered Canada the "best treatment of any major exporter to our market."

The Trump administration asserts the new tariffs are intended to address Canada's "substantial retaliation" and "discrimination" against American products and businesses. Exemptions will be in place for energy, fish, and critical minerals.

President Trump had initially set a deadline of early Saturday morning for an agreement, but extended it to allow for eleventh-hour discussions. Trump had expressed optimism in the hours before the deadline, citing his "good relationship" with Canadian Prime Minister Mark Carney and suggesting a deal was imminent. He also indicated simultaneous negotiations were underway with Mexico.

The tariff announcement follows a period of intense and delicate negotiations. Canadian Minister of Internal Trade Dominic LeBlanc described the talks as "complex and consequential," noting the significant pressure on both sides. "This is an intense moment. The stakes are significant… That pressure is being felt by Canadians across the country," LeBlanc stated.

This trade action is enabled by Section 338 of the Tariff Act of 1930, a law enacted during the Great Depression that allows the president to impose tariffs of up to 50% on imports from countries deemed to discriminate against U.S. businesses. Unlike some previous tariffs, this measure does not require a trade investigation and has no set time limit.

Canada is the second-largest trading partner for the U.S., with nearly 72% of Canada's goods exports directed to the American market. However, the U.S. recorded a goods trade deficit of $46.4 billion with Canada in 2025. Last year, Canada was one of the few nations to impose retaliatory tariffs against the U.S. in response to broader levies implemented by the Trump administration. In February, the Supreme Court invalidated those earlier tariffs, ruling the president lacked the authority under the International Emergency Economic Powers Act to impose them.

Discussions reportedly included the U.S. pushing Canada to end its retaliatory measures, such as bans on U.S. liquor and duties on American automobiles. Canada, meanwhile, sought reductions in U.S. tariffs on automobiles and other goods, aiming for lower rates on Canadian-built vehicles and on Canadian steel and aluminum.

During earlier discussions, President Trump had suggested that an agreement to revive the Keystone XL pipeline project could be part of a final trade deal. The Keystone XL pipeline was previously halted under the Biden administration.
