## Summary

Canada's retaliatory tariffs on $20bn (£15.8bn) of American goods came into force at 12.01am on Tuesday, marking the culmination of a trade war that has increasingly spilled over into open diplomatic hostility between Donald Trump and Mark Carney. The measures, ranging from 15% to 50%, answered Trump's own 50% tariff on Canadian goods imposed on 22 August, and arrived a day after Trump escalated tensions further by threatening to block US sales of Quebec planemaker Bombardier unless it shifts manufacturing stateside — a demand the firm rebuffed by pointing to the "tens of thousands" of American jobs it supports across more than 20 states and its $2.5bn annual spend with roughly 2,800 US suppliers.

Canada's tariffs target steel, dairy, appliances, agricultural equipment, pulp and paper and electronics, while the US tariffs they answer hit items such as hockey sticks and cement, affecting about 5.5% of Canadian exports. The rupture followed the collapse of negotiations on 21 August, when Carney said Washington's terms were unacceptable, citing last-minute US restrictions on Canadian trade deals with other countries and threats to French-language protections in Quebec, which a US trade official later downplayed. Trump has also made symbolic gestures such as renaming Lake Ontario "Lake America", while Carney vowed to reduce Canada's economic reliance on the US. Polls suggest Carney retains broad domestic support, though analysts warn this could erode as the trade war's costs become clearer, and only 20% of Americans approve of Trump's tariffs on Canada, according to a Reuters/Ipsos poll.
