President Donald Trump announced he is ending “all trade negotiations” with Canada because of a television advert sponsored by one of its provinces that used the words of former president Ronald Reagan to criticise US tariffs — prompting the province’s leader to later pull the ad.

The post on Mr Trump’s social media site on Thursday ratcheted up tensions with the US’s northern neighbour after Canadian Prime Minister Mark Carney said he plans to double his country’s exports to countries outside the US because of the threat posed by Mr Trump’s tariffs.
