Trump Ends Trade Talks with Canada over Ontario Reagan Tariff Ad

US President Donald Trump has terminated all trade talks with Canada following an advertisement campaign by Ontario's government that used audio from a 1987 speech by former President Ronald Reagan criticizing tariffs. The ad, part of a $75 million campaign opposing American tariffs, argued that protectionist policies cause economic harm and job losses, prompting Trump to label the ad as "FAKE" and accuse it of interfering with an upcoming US Supreme Court ruling on tariff legality. The Ronald Reagan Foundation condemned the ad's use of Reagan's words without permission, stating it misrepresented his original remarks and was reviewing legal options. Canada's economy has been significantly affected by Trump's tariffs on key exports such as autos, steel, and aluminum, leading to a strained trade relationship despite previous diplomatic efforts including a recent meeting between Trump and Canadian Prime Minister Mark Carney. Carney emphasized Canada's commitment to protecting its markets if US trade negotiations fail, while Trump defended tariffs as vital to the US economy and national security. This development marks a major setback in US-Canada trade relations amid ongoing disputes over tariff policies and legal challenges.
