Trump Orders 50% Tariff on Canadian ImportsUS President Donald Trump has imposed a 50% tariff on a broad range of goods imported from Canada, saying it was a response to what he described as “unequal treatment” of American cars, dairy products and alcohol. The new duties will come into force within 30 days and represent a significant escalation in trade tensions between the neighbouring countries. The White House said the measures are intended to safeguard US businesses, adding to a range of existing tariffs already affecting bilateral trade. Tariffs start in 30 daysThe executive action was introduced through three proclamations issued on Monday. No reference was made to Canadian wildfire smoke, despite Trump’s earlier threat to impose tariffs on that basis, with the orders instead listing trade irritants previously identified between Washington and Ottawa. The White House said the tariffs are necessary to protect US industry, while Canada’s government has not yet publicly set out its response to the latest decision. Scope and USMCA coverageThe 50% duties cover a wide range of products, from everyday consumer items such as wine and hockey sticks to industrial goods including commercial cement. Several major exports will be exempt from the new tariffs. These include energy, potash, critical minerals and fish. The tariffs apply to all covered goods regardless of whether they were already included under the US free-trade agreement with Canada and Mexico, known as the USMCA. Existing trade barriers and retaliatory measuresMonday’s announcement adds to tariffs already in place between the two countries. The US has maintained active duties of between 15% and 50% on Canadian steel, aluminium and copper. It also charges 35% on Canadian softwood lumber and imposes a 25% tariff on non-US parts used in cars. Canada has responded with a 25% counter-tariff on selected imports from the US, including steel, aluminium and vehicles. The new measures are also linked to longer-running disputes. Trump’s orders accuse Canada of imposing a tax on US-made motor vehicles and parts that he says are not covered under USMCA. He said the approach was “unreasonable” and that Canada discriminated against the US by charging no similar levy to other countries. US and Canadian automotive production is closely connected, with supply chains spanning both countries and Mexico. In the past, Trump’s commerce secretary Howard Lutnick has said he believes Canada should “come second” to the US. Trump also pointed to dairy, where the US has complained about Canada’s supply management system, which limits foreign imports. Imports above the system’s thresholds are subject to tariffs that can rise above 300%. Alcohol is another sticking point. Most Canadian provinces have maintained a boycott of US booze imposed last year, which Canadian premiers have said will be lifted if Washington removes its tariffs on key sectors including metals and automobiles. Canadian trade negotiators have been trying to reach an arrangement that would reduce at least some of the current US tariffs. Legal basis and reactionThe US Supreme Court in February struck down sweeping international tariffs introduced by Trump using the International Emergency Economic Powers Act of 1977. The judges said the president had exceeded his authority because the measures were announced under a legal framework intended for national emergencies. The White House said at the time that it would instead use other mechanisms to impose import taxes. The Monday duties were brought in under Section 338 of the 1930 Tariff Act, which addresses trade discrimination rather than national emergencies. Candance Laing, head of the Canadian Chamber of Commerce, described the step as “regrettable” but urged officials to make “meaningful progress” in talks before the tariffs take effect in 30 days.
