US President Donald Trump announced an increase in tariffs on Canadian goods by an additional 10%, following the airing of a controversial advertisement that utilized remarks from former President Ronald Reagan. The ad was broadcast during the World Series, prompting Trump's reaction, where he described it as a "fraudulent advertisement" that misrepresented Reagan's views on tariffs. Trump expressed his views on his Truth Social platform, asserting that the ad was broadcast "knowing that it was a fraud," thus justifying the tariff hike as a necessary economic measure, according to India Times and Channel News Asia.

The advertisement, produced by the Canadian province of Ontario, featured sections of a 1987 radio address by Reagan, which conveyed warnings against high tariffs leading to trade wars. Trump's decision to impose the tariffs came just days after he halted all trade discussions with Canada in light of the ad, which he called a “hostile act” and a misrepresentation of Reagan's stance on tariffs. The Ronald Reagan Foundation has criticized the advertisement for its selective editing, stating it did not seek permission to use the former president's remarks, according to India Times and The Hill.

In the wake of the tariff increase, Canadian leaders, like Prime Minister Mark Carney, have condemned the tariffs as dangerously high, comparing them to levels last recorded during the Great Depression and signaling a need for significant adjustments in Canada's economic strategy. Brampton Mayor Patrick Brown defended the controversial ad, arguing that it was a necessary provocation to elicit a response from the U.S. administration. He emphasized that the ad conveyed truthful messages regarding the long-term implications of tariffs, according to India Times and AA.
