Trump Pauses 50% Canada Tariffs for Three Days, Floats Reviving Keystone XL

Today’s Focus

President Donald Trump on Tuesday night paused a scheduled 50% tariff hike on Canadian goods for three days, hours before the duties were set to take effect, according to The Guardian and Axios.

In a post on his social media platform, Trump said the delay was granted “based on the fact that Canada and the USA, subject to the finalization of documents, have a DEAL!” The Guardian reported that the affected trade covered roughly $20 billion in Canadian exports, ranging from wine to hockey sticks.

Canadian Prime Minister Mark Carney confirmed the pause in a statement quoted by The Guardian, saying “substantial progress” had been made toward a broader trade agreement but that additional work remained before a final text could be signed.

In the same post announcing the tariff pause, Trump wrote that the Keystone XL oil pipeline “may be awoken from the grave,” without specifying whether the project’s revival was tied to the trade talks, according to The Guardian.

Keystone XL was first proposed in 2008 to move crude from Alberta’s oil sands to refiners on the US Gulf Coast. TC Energy, the Canadian pipeline operator, canceled the 1,200-mile project in 2021 after President Joe Biden revoked a cross-border permit on his first day in office.

The pause follows a year of strained relations between Washington and Ottawa. CNBC and BBC reported that the two countries had traded tariffs and public jabs for months, with Trump at times floating the idea of Canada becoming a US state.

The three-day window sets a Friday deadline for negotiators to finalize documents. Carney did not commit to a specific concession on energy infrastructure, and the White House did not release details of the framework.

The Debate

Supporters argue

Backers of the pause and the potential Keystone XL revival frame the deal as leverage working as designed. Trump wrote on Truth Social that Canada had come to the table only because of the tariff threat, casting the three-day pause as evidence of “a DEAL” being close, according to The Guardian.

Energy-industry groups have long argued that Keystone XL would expand North American oil supply and lower prices. The American Petroleum Institute has repeatedly said the pipeline would create construction jobs and reduce reliance on overseas crude, positions the group reiterated in past statements cited by Reuters.

Republican officials in oil-producing states echoed that case. Fox News coverage of prior Keystone debates has quoted lawmakers from Montana, South Dakota and Nebraska who argue the project would generate property-tax revenue and union pipefitter work along the route.

Supporters of the tariff strategy point to Carney’s own words. His acknowledgment of “substantial progress,” reported by The Guardian, is cited by administration allies as proof that hardball trade tactics produce concessions faster than traditional diplomacy.

Critics argue

Critics say the on-again, off-again tariff threats are destabilizing to businesses on both sides of the border. Canadian Chamber of Commerce president Candace Laing has previously told CBC that repeated tariff cliffs make investment planning impossible for manufacturers and farmers.

Environmental groups reject any revival of Keystone XL. The Sierra Club and Indigenous Environmental Network, quoted in past Guardian coverage, have said tar-sands crude carries higher lifecycle emissions than conventional oil and that spills along the route would threaten the Ogallala Aquifer.

Native American tribes along the original route, including the Rosebud Sioux, filed suit against earlier permits and have said any new attempt would face the same legal opposition, according to reporting by The Guardian and PBS NewsHour.

Democratic lawmakers argue the pipeline is also commercially obsolete. Sen. Ed Markey (D-MA) and other members of the Senate climate caucus have said TC Energy walked away in 2021 because the economics no longer worked, and that reviving it now would require fresh federal subsidies or guarantees.

What the experts say

Independent trade economists say the macroeconomic stakes of a US-Canada tariff war are significant. The Peterson Institute for International Economics estimated in a February 2025 analysis that broad tariffs on Canadian and Mexican goods would cost the average US household more than $1,200 per year through higher prices.

The Congressional Research Service has documented that Canada is the largest single source of US crude oil imports, supplying about 60% of foreign crude in 2024, most of it heavy grades suited to Gulf Coast refineries.

On Keystone XL specifically, the US State Department’s 2014 Final Supplemental Environmental Impact Statement concluded the pipeline would not significantly change global greenhouse-gas emissions because the oil sands would likely be developed regardless, though it also found that alternative rail transport carried higher spill and accident risks.

RAND Corporation researchers writing on North American energy integration have noted that any revived project would need new permits, new right-of-way negotiations, and a shipper willing to sign long-term contracts, a process typically requiring several years even without litigation.
