US President Donald Trump has said he will halt all trade negotiations with Canada immediately over an advert in which his predecessor Ronald Reagan says tariffs hurt every American. The ad, sponsored by Canada's province of Ontario and released last week, features excerpts of an address Reagan gave in 1987 focusing on foreign trade. Trump labeled the advert FAKE, while The Ronald Reagan Foundation said it misrepresents the former president's address. While the minute-long advert includes excerpts from Reagan's original five-minute-long address, it alters the order of his comments.

The advert opens with Reagan stating, When someone says, 'let's impose tariffs on foreign imports', it looks like they're doing the patriotic thing by protecting American products and jobs. And sometimes, for a short while it works, but only for a short time. These words were spoken by Reagan but appear midway through his original address, where he elaborates on his aversion to tariffs and the positive impacts of free trade.

The advert continues with the line, Over the long run, such trade barriers hurt every American, worker and consumer. Again, these words come from Reagan's address but are not sequentially linked in the original context, where a significant amount of speech separates them.

The ad emphasizes Reagan's concerns about tariffs leading to retaliation and trade wars, a message he elaborated on throughout his address, noting the historical lessons learned from high tariffs during the Great Depression. Trump's strong reaction reflects ongoing tensions and complexities in US-Canada trade relations, as both nations navigate the implications of tariffs and trade policies.
