Trump’s Sudden U-Turn On Canada Tariffs As 50% Duties Are Paused

US President Donald Trump has paused planned 50% tariffs on about $20 billion of Canadian goods for three days, saying the United States and Canada have reached a deal that still needs to be finalized. The last minute move has eased immediate trade pressure, but it has also brought the controversial Keystone XL oil pipeline back into focus.

Trump announced the tariff pause on Truth Social shortly before the new duties were due to take effect on Wednesday. He said the United States and Canada had a deal, subject to the completion of documents. Canadian Prime Minister Mark Carney also confirmed that substantial progress has been made, but said important work remains.

The proposed tariffs would have affected a range of Canadian products, including wine, dairy goods, liquor, cement and hockey equipment. The White House had announced the 50% duties in July, accusing Canada of unfair treatment of American products. The tariffs were set to apply from August 19 under Section 338 of the 1930 Tariff Act.

The pause has also turned attention to Keystone XL, a long delayed pipeline project designed to carry crude oil from Alberta to refineries in the United States. The proposed pipeline would have stretched about 1,947 kilometres from Hardisty, Alberta, to Steele City, Nebraska, with planned capacity of 830,000 barrels of oil a day.

Trump said the “great Keystone XL pipeline”, which he blamed former President Joe Biden for killing, could be brought back. However, he did not provide a detailed plan or confirm that the pipeline's revival is part of the new trade understanding. Current reports also do not show a formal decision to restart the project.

Keystone XL became one of the most politically charged energy projects in North America. Supporters argued that it would provide a major route for Canadian oil and strengthen energy ties between the two countries. Critics, including environmental groups, landowners and Indigenous communities, raised concerns over oil spills, land use and climate change.

The project was effectively halted in January 2021 when Biden revoked the U.S. presidential permit. TC Energy then suspended the project. Canada's energy regulator said the company would have to meet regulatory requirements for any future changes involving the Canadian section.

The pipeline debate comes as US-Canada trade tensions have already grown sharply. Earlier tariff measures and Canada's retaliatory actions have put pressure on businesses on both sides of the border. Ottawa has also pushed to reduce its dependence on the U.S. by seeking new trade and investment partners.

Trump has repeatedly used tough language when discussing Canada, including his past suggestion that Canada could become the 51st U.S. state. Canadian leaders have pushed back, stressing that the country can build stronger economic ties beyond the United States.

For now, the three day tariff pause gives Washington and Ottawa time to finish their discussions. But Keystone XL's possible revival could open another major political fight, especially if a future proposal requires new permits, environmental reviews and talks with affected communities.

The immediate tariff threat may have eased, but the wider dispute is far from settled. The coming days will show whether Trump's latest announcement leads to a lasting trade agreement or simply creates another short pause in the long running U.S.-Canada economic battle.
