In a dramatic turn of events, Canada and the United States have reached a last-minute trade agreement that has temporarily averted a 50% tariff on Canadian exports. The deal, announced late on Tuesday evening, came just hours before the punitive tariffs were set to take effect at 12:01 a.m. Wednesday. The agreement, which covers $20 billion worth of goods, has provided a temporary reprieve for Canadian businesses and has eased tensions between the two historic allies.
The announcement was made by President Donald Trump on his social media platform, Truth Social, where he stated that the tariffs had been paused for a three-day period. “Based on the fact that Canada and the USA, subject to the finalization of documents, have a DEAL!” Trump posted, indicating that substantial progress had been made towards a trade agreement.
Keystone XL Pipeline Resurfaces in Trade Talks
The trade agreement also brought the controversial Keystone XL pipeline project back into the spotlight. Trump hinted that the project “may be awoken from the grave,” although he did not provide further details or suggest whether it was linked to the tariffs deal. The Keystone XL pipeline, which was proposed in 2008 to bring oil from Canada’s western tar sands to US refiners, was halted in 2026 by owner TC Energy after Joe Biden revoked a key permit needed for a US stretch of the 1,200-mile (1,930km) project.
The pipeline has been a flashpoint in US-Canada relations, amid opposition from US landowners, Native American tribes, and environmentalists. North American oil pipelines, including Dakota Access and Enbridge Line 3, have faced steady opposition from environmental groups, amid concerns about spills.
Historical Context and Recent Tensions
The latest deal comes amid a contentious past year for the two countries, with the longstanding alliance strained by tit-for-tat tariffs and online broadsides. In, the White House hit Canada with a 25% tariff, citing what it regarded as inadequate progress in curbing cross-border illegal immigration and drug trafficking. In retaliation, Canada announced a reciprocal levy, calling the US’s actions “unwarranted and unreasonable.”
Tensions flared again in July 2026 when the White House announced the 50% tariffs, saying that it sought to hold Canada accountable for discrimination against US-produced cars, alcohol, and dairy products. The proposed tariffs would have affected a range of Canadian exports, including wine and hockey sticks.
Intense and Delicate Negotiations
In recent days, top officials from the two countries were engaged in “intense and delicate” talks, according to Canadian Prime Minister Mark Carney. The negotiations were aimed at finding a mutually beneficial agreement that would avoid the financial devastation and untenable export costs that the proposed tariffs would have caused.
Historically, Canada and the US have been strong trading partners. In 2026, trade between the countries was estimated to be roughly $909 billion, according to the office of the US trade representative. The latest proposed US levy has stoked concern about financial devastation and untenable export costs among Canadian business owners.
Economic and Political Implications
The political impact of the tariffs would likely have been bigger than the economic one. Canada had threatened to retaliate against any new tariffs with levies of its own, aggravating a trade fight between countries that sold each other $880 billion worth of goods and services last year. Nearly 72% of Canada’s goods exports last year went to the United States, highlighting the importance of the trade relationship.
The Trump administration would be taking a risk by imposing a hefty new tariff ahead of November’s midterm elections. US voters are already frustrated with the high cost of living, and the tariffs would likely have added to their concerns. “I don’t think either side really wants these tariffs to come into effect,” said Ryan Majerus, a partner at King & Spalding and a former US trade official.
Canadian Chamber of Commerce President and CEO Candace Laing said in a statement that the three-day tariff delay offered businesses some relief but fell short of the certainty a signed interim agreement would provide. “This limbo state is not anyone’s preferred outcome,” she said, urging negotiators to reach a deal quickly.
Trump’s approach to dealing with Canada marks an extraordinary departure from the traditionally cooperative relationship between the two countries. Trump has hit Canadian goods with tariffs in a push to bring manufacturing back to the US and has repeatedly made inflammatory comments about turning Canada into America’s 51st state.
Trump has made tariffs the centerpiece of his second-term economic agenda. Last year, he imposed double-digit import taxes on almost every country, justifying them by declaring the longstanding US trade deficit a national emergency. The Supreme Court in February ruled that he’d overstepped his authority, striking down those tariffs and setting the stage for the federal government to pay refunds to importers.
To hit Canada, Trump reached back to the Great Depression, invoking Section 338 of the Tariff Act of 1930 to threaten 50% tariffs on products that account for about 5% of Canadian exports to the United States. Section 338 authorizes the president to impose tariffs of up to 50% on imports from countries that have discriminated against US businesses. No investigation is required to justify the levies, nor is there any limit on how long the tariffs can stay in place.
The US is renegotiating a North American trade pact—the US-Mexico-Canada Agreement (USMCA)—that Trump strong-armed America’s neighbors into accepting in his first term. The threat of Section 338 tariffs gives the United States leverage to seek fresh concessions from Ottawa.
