President Donald Trump signed an executive order raising a 50% tariff on a wide range of Canadian goods, citing 'unequal treatment' of U.S. automobiles, dairy and alcohol imports. The tariff, which will take effect on 19 August, marks a steep escalation in trade tensions between the neighbouring countries.

The move aims to protect American businesses, but it builds on the existing U.S. duties on Canadian steel, aluminium and lumber – ranging from 15 % to 50 %. It also adds a 35 % levy on Canadian softwood lumber and a 25 % duty on non‑U.S. automotive parts.

Canadian pros and farmers have warned that the new duties will hit everyday consumer items – from wine and hockey sticks to cement and other industrial goods – while sparing critical exports such as energy, potash, minerals and fish.

Trade negotiators have struggled to find a compromise over tax on Canadian motor vehicles, supply‑management limits on dairy, and the long‑standing boycott of U.S. alcohol by Canadian provinces. The new tariff signals that diplomatic talks are moving in the wrong direction for Canada.

Canadian business leaders have criticised the wide‑spectrum tariff, noting that the looming impact could erode many exports and they continue to push for a reversal of the new duties.
