In a recent diplomatic incident, Canadian Prime Minister Mark Carney issued an apology to US President Donald Trump following an anti-tariff advertisement that referenced Ronald Reagan. The ad, which Carney advised against, reportedly upset Trump, leading to the cessation of trade talks between the two countries. Trump described the ad as offensive and counterproductive, prompting him to raise tariffs on Canadian goods by 10%. Carney confirmed his apology during discussions at an APEC Summit dinner, stating that the advertisement was not something he would have supported. The fallout from the ad continues to strain US-Canada relations, with Trump expressing doubts about the feasibility of restarting trade negotiations.
