U.S. President Donald Trump announced on Thursday that he had terminated trade negotiations with Canada in response to an advert produced by the government of Ontario featuring historic footage of President Ronald Reagan arguing that tariffs undermine economic prosperity.

President Donald Trump has announced trade talks with Canada will cease, claiming our northern neighbor “fraudulently” used an ad featuring the late Ronald Reagan speaking negatively about tariffs.

US President Donald Trump halted all trade negotiations with Canada earlier this week over an advert in which former President 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 slaps Canada with additional 10% tariff over a disputed Reagan ad that aired during World Series, calling it a "fraudulent misrepresentation" of the former president.

President Trump abruptly called off trade negotiations with Canada on Thursday over an anti-tariff ad campaign, featuring the voice of Ronald Reagan, funded by the government of Ontario.

By the weekend, negotiations between Washington and Ottawa were frozen, and President Donald Trump had imposed fresh tariffs.

In a late-night social media post, the U.S. President accused Canada of misusing former President Ronald Reagan’s words against his tariffs.

The ad spliced clips of the former president’s 1987 address in which he warns that tariffs “hurt every American.” In response, Trump branded the ad “crooked,” announced he was suspending trade talks with Canada, and then imposed a 10 percent additional tariff on the country after Ford delayed pulling the ad.

Ontario Premier Doug Ford said Friday the anti-tariffs advertisement featuring former President Reagan, which angered President Trump, will air during the World Series before being paused Monday.
