特朗普称卡尼为反关税广告道歉，但美加谈判不会重启，加股盘中转跌

Core Viewpoint - The trade negotiations between the U.S. and Canada remain stalled, primarily due to tensions arising from a controversial advertisement funded by the Ontario government that utilized former President Reagan's voice to criticize tariffs, which has provoked a strong reaction from President Trump [1][8][9]. Group 1: Trade Negotiations Status - President Trump has explicitly stated that he does not plan to resume trade negotiations with Canada, despite a friendly relationship with Prime Minister Ford [1][9]. - Following Trump's announcement to halt negotiations, the Canadian benchmark stock index S&P/TSX and the Canadian dollar experienced declines [1][4]. - Prime Minister Ford indicated that the Ontario government would pause the controversial advertisement, but Trump expressed dissatisfaction with the delay in its removal [9][10]. Group 2: Economic Impact - The trade war is impacting Canada's economy, with a reported GDP contraction of 0.3% in August and a minimal growth of 0.1% in September, leading to an estimated annualized GDP growth rate of only 0.4% for the third quarter [7][12]. - Canada currently faces a 35% basic tariff from the U.S., although most exports enjoy zero tariffs due to the USMCA agreement [12]. Group 3: Advertisement Controversy - The Ontario government funded a $75 million advertisement that used Reagan's voice to argue against tariffs, which Trump deemed a "fraudulent" use of Reagan's words [8][9]. - The ad was designed to provoke discussion about the economic impact of tariffs on American workers and businesses, but it has intensified the uncertainty in U.S.-Canada trade relations [8][10]. Group 4: Future Negotiation Prospects - Prime Minister Ford and Prime Minister Trudeau have expressed readiness to resume negotiations when the U.S. is prepared, with discussions on steel, aluminum, and energy making progress prior to the halt [11][12]. - U.S. Energy Secretary Chris Wright acknowledged the existing friction but emphasized the goal of returning to the negotiation table to enhance cooperation in key sectors [11].
