Trump says he's ending 'all trade negotiations' with Canada

US President Donald Trump said Friday he was cutting off "all trade negotiations" with Canada because of a "fraudulent" ad campaign against US tariffs.

Trump was referring to a television advertisement aired by the government of Ontario province that featured former President Ronald Reagan's warnings about the long-term risk of tariffs.

Earlier, Canadian Prime Minister Mark Carney also said wanted to double his country's exports to countries outside the US because of the threat posed by Trump's tariffs.

What did Trump say about Canada?

"The Ronald Reagan Foundation has just announced that Canada has fraudulently used an advertisement, which is fake, featuring Ronald Reagan speaking negatively about tariffs," Trump posted to Truth Social.

He then continued, saying: "Tariffs are very important to the national security and economy of the USA. Based on their egregious behavior, all trade negotiations with Canada are hereby terminated."

Ontario Premier Doug Ford, who has played a key role in trade negotiations with the US, announced the ad campaign earlier this month.
