President Donald Trump said on 18 August 2026 that he would postpone a planned 50% tariff on a broad range of Canadian goods for three days, saying the delay reflects progress toward a broader trade agreement with Ottawa. The reprieve came less than two hours before the tariff, covering close to $20bn (C$28bn) of Canadian imports, was due to take effect. Trump also suggested the eventual deal could revive the long-stalled Keystone XL pipeline project.
Announcing the pause on social media, Trump wrote:
I have paused the 50% Tariffs against Canada, that were scheduled to kick in tomorrow morning for a three day period, based on the fact that Canada and the U.S.A., subject to the finalization of documents, have a DEAL!
On the pipeline, which would carry oil from Alberta into the United States, Trump wrote on Truth Social:
The great Keystone XL Pipeline, long ago killed by Sleepy Joe Biden, may be awoken from the grave!
Why did trade talks reach this point?
Trump had originally signed an order imposing the 50% tariff on a wide swath of Canadian goods with an effective date of 19 August 2026, before the White House confirmed the move and gave a 30-day window before enforcement, as detailed in our earlier coverage of the announcement. In the days before the deadline, Prime Minister Mark Carney faced what our reporting described as a scramble to close the gap with Washington on autos, dairy and alcohol, as outlined in our report on Carney's final hours of negotiation before the deadline. Trump and Carney spoke twice during the week leading up to the pause, and negotiators had been engaged in continuous talks since Trump first threatened the escalated levy.
What concessions are being discussed?
According to a report by a global financial news wire, the threatened tariffs targeted goods that would otherwise have qualified for duty-free treatment under the North American free trade agreement between the US, Mexico and Canada, meaning the dispute reached beyond the normal terms of that framework, as noted in a wire service account of the standoff. Negotiators had reportedly been discussing lowering the US tariff on Canadian autos from 25% to 15%, though the two sides could not agree on which vehicles would qualify, with Washington pushing to limit relief to cars containing a high share of American-made parts, according to that same account. The New York Times separately reported that Canada had offered to repeal its own retaliatory tariff on US-made autos as part of the broader package, according to the New York Times. The proposed US tariffs were also tied to Canadian dairy, alcohol and other goods, while Washington sought looser Canadian dairy quotas to give US cheese producers greater market access, according to a separate wire service report on the state of the talks, which can be read here. Washington also wanted Canadian provinces to lift bans on US alcohol sales that were imposed last year in retaliation for earlier tariffs. CBC News reported that Canada's trade minister and chief negotiator held multiple meetings with US counterparts in Washington over the preceding weekend as both sides tried to keep momentum going, according to CBC News, which added that the talks also aimed to ease existing US tariffs on steel, aluminium, autos and lumber.
How have businesses and provincial leaders responded?
Any rollback of the provincial alcohol bans will require the agreement of individual premiers, since liquor sales fall under provincial rather than federal jurisdiction. Ontario Premier Doug Ford, whose province has borne the brunt of the US auto tariffs, indicated conditional support, saying he was open to lifting the ban only if a "fair deal" is reached. Business groups on both sides of the border had urged negotiators to avoid a further escalation. On 18 August 2026, the US Chamber of Commerce pressed for a resolution, warning in a statement:
Higher tariffs would damage both economies, drive up costs for US families, further disrupt critical supply chains, and risk the 13 million American jobs that depend on trade under the US-Mexico-Canada Trade Agreement.
What happens next?
Both governments are now racing to finalize the documents underpinning the agreement Trump referenced, with the three-day pause meant to bridge the gap before the tariffs would otherwise take hold, according to the wire service report on the run-up to the deadline. CBC News reported that negotiating teams were expected to continue intensive discussions through the remainder of the window. Central outstanding questions include whether Washington will scrap the newly threatened 50% tariff outright or instead adjust existing US duties on Canadian steel and aluminium, a point still under negotiation according to the wire service's account of the concessions being weighed.
