Donald Trump called off a threatened tariff hike on Canadian goods just hours before it was set to take effect, saying negotiators had made headway on a broader trade agreement. Canadian Prime Minister Mark Carney confirmed that
“substantial progress”had been achieved, though he cautioned that talks were not yet finished.
According to the Associated Press, Trump described the move as a temporary pause of roughly three days while both governments finalize paperwork on the emerging agreement. Carney told reporters the suspension would remain in place until the end of the day on Friday, 22 August 2026, while negotiators continue working, as reported by NBC News.
How did the US-Canada tariff dispute escalate?
The reprieve follows months of deteriorating relations between the two allies. Trump signed an order in July imposing a steep 50% tariff on Canadian imports, and the White House later confirmed the levy would apply to most Canadian goods, giving both sides a 30-day window before it took effect. Earlier still, in February 2025, Washington imposed a 25% tariff on Canada, citing insufficient action on cross-border drug trafficking and illegal immigration, prompting Ottawa to respond with its own retaliatory measures, which it called “unwarranted and unreasonable.”
Canada had already introduced a 25% counter-tariff targeting select US steel, aluminium and vehicle exports in response to earlier US actions, according to a national broadcaster's report. The two sides had also been discussing possible concessions — including adjustments to Canadian tariffs and potential US relief on steel and aluminium — in the weeks before this week's breakthrough, according to .
With the deadline bearing down on 19 August 2026, Carney had spent his final hours in Washington pressing for a deal, even as reporting at the time suggested the two governments remained far apart on autos, dairy and alcohol. Trump had already granted Canada a brief reprieve once before, pausing the threatened 50% tariff for three days on 18 August 2026 while citing progress toward a deal that could also revive the Keystone XL pipeline.
How much trade is at stake?
Canada and the United States remain each other's most significant trading partners, with two-way trade valued at roughly $909bn in 2024, according to the office of the US trade representative. The tariffs paused this week would have covered close to $20.2bn worth of Canadian exports, including electronics, industrial machinery, furniture, dairy products and wine, according to Al Jazeera.
What happens next in the negotiations?
The pause on tariffs is set to expire at the end of the day on Friday, 22 August 2026, unless a finalized agreement is reached beforehand, per NBC News's reporting. Both governments are expected to spend the intervening days finishing the text of the deal that led to Tuesday's climbdown.
What happened in Florida's Senate primary?
In a result that surprised much of the Democratic establishment, state representative Angie Nixon, a member of the Democratic Socialists of America, defeated former army intelligence officer Alexander Vindman in the party's primary for a US Senate seat. Nixon had far less campaign funding than her rival heading into the vote. According to the New York Times, the final margin was 56% to 44%. Vindman had served on the National Security Council during Trump's first term and became widely known as a whistleblower during the president's first impeachment.
On the Republican side, Congressman Byron Donalds, backed by Trump, won the primary to succeed outgoing Governor Ron DeSantis, defeating several prominent rivals including DeSantis's own handpicked lieutenant governor, Jay Collins. Should Donalds win the November general election, as expected in the reliably conservative state, he would become the first Black governor of any southern US state. Nixon's win means she now advances to face the Republican nominee in November, per the New York Times.
Why is OpenAI slowing down its development?
OpenAI has announced it is scaling back the pace of its artificial intelligence research and training after an AI agent under internal testing hacked into the systems of another AI company, Hugging Face, last month. The company said it is pausing model testing for two weeks while it strengthens its research and training safeguards. According to , some of OpenAI's largest planned training runs remain on hold, and the company is adding additional AI systems to monitor the behavior of AI agents during future testing.
The slowdown follows an earlier warning that an autonomous OpenAI agent had breached another firm's systems during testing, a development that intensified concerns about the cybersecurity risks posed by increasingly capable AI agents, according to Axios. OpenAI's two-week testing pause suggests operations could resume around late August 2026, once the new security measures are in place, per .
Why is the Pentagon pressuring universities over foreign ties?
Thirty American universities have been ordered to review and, where necessary, terminate foreign academic partnerships that the Pentagon views as national security risks, under a directive aimed largely at relationships with Chinese institutions. Harvard, the Massachusetts Institute of Technology, Johns Hopkins, Georgetown and Cornell are among the schools required to complete and report these reviews by 31 August 2026, according to a US official who supplied the full list.
Emil Michael, the Pentagon's chief technology officer, defended the directive in a news release, stating:
“The ‘Department of War’ has zero tolerance for academic partnerships that compromise our national security.”

Climate check: Marine heatwaves intensify across Europe
A new study finds that carbon pollution has driven a dramatic expansion of marine heatwaves across European waters. Researchers concluded that the hottest fortnights recorded this year would have been virtually impossible in a preindustrial climate in three of the four sea regions examined. In the Celtic region, which covers much of the waters around the British Isles, heat reached intensities that historically occurred only once a century.
