Here’s what Trump is doing.
President Donald Trump has temporarily paused a major new round of tariffs against Canada, announcing a dramatic three-day delay just hours before a 50% tariff on billions of dollars in Canadian imports was scheduled to take effect.
The last-minute decision gives the United States and Canada additional time to finalize a potential trade agreement following intensive negotiations between Trump and Canadian Prime Minister Mark Carney.
But another development could prove even more significant.
Trump suggested that the long-stalled Keystone XL pipeline could potentially return as Washington and Ottawa negotiate the future of their economic relationship.
The combination of tariffs, trade negotiations and a possible revival of the massive energy project could have important consequences for American businesses, energy markets and consumers.
Trump Pauses 50% Canada Tariffs
Trump announced the temporary tariff pause Tuesday evening, less than two hours before the new import taxes were scheduled to take effect.
The president said the United States and Canada had reached an understanding that remained subject to the completion of final documents.
The pause lasts three days, providing negotiators with a short window to settle the remaining issues.
Canadian Prime Minister Mark Carney has taken a more cautious approach, saying substantial progress has been achieved while acknowledging that additional work remains before negotiations are complete.
That distinction is important: Trump has announced a deal, but the final terms have not yet been publicly released.
For American businesses and consumers, the pause means the threatened 50% tariffs will not immediately hit the affected Canadian products while negotiations continue.
Could Keystone XL Make a Comeback?
Trump drew additional attention when he suggested that the Keystone XL pipeline, canceled during former President Joe Biden’s administration, could potentially be revived.
After announcing the tariff pause, Trump posted an AI-generated image showing himself pulling a pipeline labeled “Keystone” from the ground beside a damaged tombstone referring to Biden.
The image reinforced Trump’s message that a project considered politically dead for years may once again be under consideration.
Exactly how Keystone XL fits into the developing U.S.-Canada trade agreement remains unclear. No finalized agreement has yet established that the pipeline will actually be restarted.
Still, Trump’s decision to publicly raise the issue puts Keystone XL back into the national debate over American energy security, oil supplies and North American energy infrastructure.
What Is the Keystone XL Pipeline?
Keystone XL was designed as a major expansion of North America’s oil transportation network.
The proposed pipeline would have transported as much as 830,000 barrels of crude oil per day from Alberta, Canada, to Nebraska.
From Nebraska, the oil could connect with existing pipelines serving refineries along the U.S. Gulf Coast.
Supporters of Keystone XL have argued for years that the project could strengthen North American energy infrastructure, support economic activity and provide the United States with greater access to Canadian oil.
Opponents have focused primarily on environmental concerns, including greenhouse gas emissions, oil spills and continued reliance on fossil fuels.
Those competing arguments turned Keystone XL into one of America’s most recognizable political battles over energy policy.
Biden Canceled Keystone XL Permit
The pipeline encountered years of political and regulatory obstacles during the Obama administration.
Trump moved to revive the project during his first presidency, making Keystone XL part of his broader push to expand North American energy development.
That changed after Biden entered the White House in January 2021.
Biden revoked a critical presidential permit needed for the pipeline to cross the U.S.-Canada border. TC Energy, the Calgary-based company developing Keystone XL, subsequently terminated the project.
Trump has repeatedly criticized Biden-era energy policies and has made expanded energy production a major component of his economic agenda.
His latest remarks suggest Keystone XL could once again become part of that agenda.
However, restarting such a massive project would likely involve considerable regulatory, financial and logistical challenges even if the United States and Canada agree to pursue it.
Tariffs Would Have Hit Billions in Canadian Imports
The proposed 50% tariffs would affect roughly $20 billion worth of Canadian products entering the United States.
That represents approximately 5% of Canada’s exports to the American market.
Products potentially affected include items such as wine, hockey equipment and certain construction materials, while several strategically important categories have been excluded.
The economic stakes extend far beyond those individual products.
The United States and Canada maintain one of the world’s largest trading relationships, with hundreds of billions of dollars in goods and services moving between the two countries annually.
American manufacturers also rely heavily on cross-border supply chains, particularly in industries such as automobiles, agriculture, construction and energy.
That means a prolonged trade dispute could affect businesses and workers on both sides of the border.
What Could Tariffs Mean for American Consumers?
Tariffs are charged on imported products, meaning American companies bringing affected Canadian goods into the United States generally pay the additional import tax.
Businesses then must decide whether to absorb those costs, find alternative suppliers or pass some of the expense on to customers.
For Americans already concerned about household expenses, that makes the outcome of the negotiations particularly important.
A successful trade agreement could prevent the threatened tariffs from taking effect while potentially securing greater access for American products in Canada.
A breakdown in negotiations, however, could revive the possibility of a wider trade confrontation.
Canada had threatened retaliatory tariffs of its own if Trump’s new duties took effect.
That could create additional pressure on American exporters selling products north of the border.
Trump Says Canada Has Treated U.S. Businesses Unfairly
Trump has accused Canada of maintaining trade policies that disadvantage American businesses, particularly in industries involving automobiles, alcohol and dairy products.
The administration turned to Section 338 of the Tariff Act of 1930 as the legal basis for the threatened tariffs.
The rarely invoked provision gives the president authority to impose tariffs of up to 50% against countries determined to have discriminated against American commerce.
Trump has consistently argued that tariffs provide the United States with powerful negotiating leverage because foreign countries depend heavily on access to the enormous American consumer market.
Supporters of that strategy say tougher trade policies can pressure foreign governments to remove barriers facing American companies and workers.
Critics counter that tariffs can raise costs for U.S. businesses, provoke retaliation against American exports and eventually contribute to higher consumer prices.
Canada Faces Enormous Economic Stakes
Canada has particularly strong incentives to reach an agreement because the United States remains by far its most important export market.
A large majority of Canadian goods exports are sold to American customers.
That economic dependence gives Washington substantial leverage, but American businesses also benefit from the extensive trade relationship between the neighboring countries.
The political dispute has nevertheless contributed to increased tensions in Canada.
A petition calling for the removal of U.S. Ambassador Pete Hoekstra, a former Michigan congressman and Trump ally, has attracted significant attention as frustration over the trade battle has grown.
Carney has largely avoided publicly discussing the details of negotiations, emphasizing the sensitive nature of the talks.
Three Days Could Determine What Happens Next
The immediate question is whether negotiators can transform the current understanding into a finalized U.S.-Canada trade agreement before Trump’s three-day tariff pause expires.
Several major questions remain unanswered.
Will Canada make new concessions for American agricultural, automobile or alcohol exports? Will the United States permanently withdraw the threatened 50% tariffs? And perhaps most importantly for the energy industry, will Keystone XL actually become part of the final agreement?
Until official documents are completed, those questions remain open.
What is clear is that Trump has temporarily pulled the United States and Canada back from another major escalation in their trade dispute.
The decision also demonstrates how the president continues to use tariffs as negotiating leverage in his broader effort to reshape America’s economic relationships.
For Americans watching energy prices, trade policy, manufacturing and household costs, what happens during this three-day negotiating window could have consequences extending well beyond the U.S.-Canada border.
A finalized agreement could prevent another tariff battle while potentially reopening one of the most consequential energy debates of the past two decades.
For now, the 50% tariffs are on hold — and the future of both the U.S.-Canada trade relationship and Keystone XL is once again in the spotlight.
