Trump Made Canada Blink — Keystone XL May Rise From the Dead

A last-minute U.S.-Canada trade truce that President Donald Trump had celebrated as a breakthrough collapsed days later, triggering new 50 percent U.S. tariffs on roughly $20 billion in Canadian goods and prompting Ottawa to promise matching retaliation.

The reversal came after a dramatic week in which Trump postponed the tariffs for three days, said the two countries had a deal subject to final paperwork and unexpectedly revived discussion of the long-defunct Keystone XL oil pipeline.

Late Tuesday, less than two hours before the duties were originally scheduled to take effect, Trump announced that he was granting Canada a three-day reprieve. In a Truth Social post, he said the United States and Canada, “subject to the finalization of documents, have a DEAL!”

Trump then added a line that immediately broadened the story beyond tariffs: “The great Keystone XL Pipeline, long ago killed by Sleepy Joe Biden, may be awoken from the grave!”

Canadian Prime Minister Mark Carney confirmed at the time that substantial progress had been made, but he stopped short of describing the negotiations as complete. In an Aug. 18 statement, Carney said there was still “important work” to be done and noted that the United States had agreed to postpone implementation of the 50 percent tariff until the end of Aug. 21.

For several days, the pause appeared to validate Trump's strategy of using a looming tariff deadline to force movement on disputes involving American alcohol, dairy products, motor vehicles and other trade issues. By Friday night, however, the tentative agreement had fallen apart.

The new duties took effect just after midnight Saturday, according to Reuters and The Associated Press. They cover about $20 billion in Canadian products, or just over 5 percent of Canada's annual exports to the United States, and apply to goods ranging from wine and dairy products to cement, furniture, clothing and hockey equipment.

Carney responded by suspending negotiations and announcing that Canada would retaliate dollar for dollar.

“I have decided to suspend trade negotiations with the U.S. and have directed Canada's negotiators to return to Ottawa,” Carney said. He accused Washington of making last-minute changes that were “unfair, uneconomic, and called into question the reliability of any deal.”

U.S. Trade Representative Jamieson Greer offered a sharply different account. He said Canada had declined to finalize terms that had been agreed earlier in the week and argued that Ottawa introduced new demands and reversed prior commitments as the deadline approached.

“Tonight, Canada declined to finalize the trade deal under the terms agreed earlier this week,” Greer said, calling the breakdown a missed opportunity for Canada.

No additional talks were immediately scheduled after the tariffs took effect, marking a significant setback for a relationship that only days earlier seemed close to producing a broader trade compromise.

The dispute centers in part on Trump's use of Section 338 of the Tariff Act of 1930, a little-used provision that allows a president to impose duties of up to 50 percent on imports from a country found to discriminate against U.S. commerce.

The White House invoked the law in July through separate proclamations concerning Canadian alcohol, dairy and motor-vehicle policies. The administration argued that Canadian provinces had discriminated against U.S. alcohol by removing American products from government-controlled liquor systems while continuing to sell products from other countries. It also accused Canada of providing less favorable market access to certain U.S. dairy products than to comparable European products and of imposing discriminatory treatment on U.S. motor vehicles.

The White House said the Section 338 tariffs were designed to offset those disadvantages and described the action as part of Trump's effort to force more reciprocal trade terms. The administration exempted some major categories, including energy, potash and goods already subject to certain national-security tariffs.

The use of Section 338 is historically significant. Although the provision has existed for nearly a century, it had never before been used to impose tariffs in this manner, according to reporting by AP and Axios. The statute gives the president broad authority to impose duties when foreign treatment of U.S. commerce is deemed discriminatory, and unlike some other trade statutes it does not require the same type of lengthy investigation before action is taken.

That legal tool became more important to the administration after the Supreme Court earlier this year struck down tariffs Trump had imposed under emergency-powers law, forcing the White House to rely on other statutory authorities for parts of its trade agenda.

The original three-day pause had raised hopes that the threatened Section 338 duties could instead be used as leverage to secure concessions. Negotiators discussed possible reductions in existing U.S. tariffs on Canadian steel, aluminum and vehicles while Canada considered steps that could restore American alcohol to provincial store shelves and address other market-access complaints.

Ontario Premier Doug Ford had publicly opened the door to ending his province's boycott of U.S. alcohol if Ottawa secured what he considered a fair agreement. “If we get a fair deal that will protect our steel sector, our auto sector, our forestry sector, agriculture sector, manufacturing sector, then we'd be more than happy to bring booze back on the shelves earlier,” Ford said on Aug. 13.

Because Canadian provinces largely control alcohol distribution, any federal promise on liquor access would require cooperation from provincial governments. The issue has become both an economic grievance and a political symbol during the broader trade confrontation.

The dairy dispute is similarly complicated. Canada operates a supply-management system that protects domestic dairy production through quotas and high tariffs outside agreed import levels. The Trump administration's July proclamation did not simply object to the existence of supply management; it specifically accused Canada of allocating tariff-rate quotas for U.S. cheese in a way that disadvantaged American producers compared with European competitors.

Canada, for its part, has argued that its retaliatory measures were responses to earlier U.S. tariffs and that Washington's actions violated commitments under the U.S.-Mexico-Canada Agreement. Carney has repeatedly said Canada is willing to negotiate, but not at any price or under terms his government considers unreliable.

The collapse also complicates the future of the USMCA, the trade agreement Trump negotiated during his first term. The United States, Canada and Mexico have been preparing for a broader review of the pact, but the latest escalation makes it harder to separate those long-term negotiations from the immediate tariff fight.

The economic stakes extend far beyond the roughly $20 billion directly targeted by the new Section 338 duties. The two countries traded about $880 billion in goods and services last year, according to AP, while Reuters reported that the affected products account for only a small portion of Canada's total exports to the United States. That means the direct macroeconomic effect of the new tariff package may be limited compared with the broader U.S.-Canada trade relationship, even as individual industries and companies could face severe disruption.

Trade specialists have warned that high tariffs can raise costs for U.S. importers and consumers while exposing Canadian exporters to lost sales, layoffs or closures. Canadian officials have said additional support for affected workers and businesses will be announced as the dispute continues.

The Keystone XL issue remains a separate but politically potent part of the story. Trump repeatedly promoted the project during his first term and has now suggested that renewed energy cooperation with Canada could bring some version of it back.

Keystone XL was originally designed as a roughly 1,900-kilometer pipeline capable of moving about 830,000 barrels of crude oil per day from Alberta's oil sands toward the U.S. pipeline network and Gulf Coast refineries. The project faced years of legal, environmental and political opposition.
