• Trump halts trade talks with Canada after a controversial anti-tariff advertisement airs.
• Canadian PM Mark Carney apologizes to Trump, claiming the ad "offended" him.
• The ad featured comments by Reagan arguing against tariffs, which Trump disputes.
• Ontario Premier Doug Ford is criticized for allowing the ad to air despite Carney's objections.
• Trump announces an additional 10% tariff on Canadian goods in response to the ad.

US President Donald Trump has confirmed that he will not resume trade negotiations with Canada after an anti-tariff advertisement aired by the Canadian province of Ontario. This advertisement featured remarks from former President Ronald Reagan that criticize tariffs, leading to tensions between the allies. Trump expressed that while he maintains a "good relationship" with Canadian Prime Minister Mark Carney, he found the ad's content "wrong" and warranted action, as reported by SCMP and Channel News Asia.

During the Asia-Pacific Economic Cooperation summit, Carney publicly apologized to Trump, acknowledging that the advertisement "offended" him. He noted his responsibility as prime minister for the relationship with the US, indicating that he had advised Ontario's Premier Doug Ford against airing the ad. Despite Carney's efforts, the ad aired during significant sporting events, which further escalated the situation, according to The Hill and LA Times.

In reaction to the advertisement, which Trump labeled as misleading and said attempted to influence pending Supreme Court proceedings on his tariffs, the US president announced a 10% increase in tariff rates on Canadian imports. The breakdown of trade talks highlights an already deteriorating relationship aggravated by previous tariff disputes, as explained by Reuters and BBC.

Carney emphasized the need for Canada to diversify its trade partnerships outside of dependency on the US, a sentiment that has been reinforced by the impact of tariffs on key Canadian industries, including aluminum and steel. Meanwhile, discussions have sparked public discourse about the integrity of political advertisements and their potential implications on international relations, according to Al Jazeera and CBS News.

The fallout from this incident illustrates the complex nature of modern diplomacy, particularly in the context of trade, where well-intentioned communications can lead to significant complications. As Carney moves forward, he plans to introduce new measures in an upcoming budget to protect and strengthen Canada's economy amidst these challenges, as further noted by India Times and Channel News Asia.
