President Donald Trump announced plans to raise tariffs on imports from Canada by another 10%, according to a TruthSocial post on Saturday. The move follows escalating tensions sparked by an anti-tariff ad campaign from Ontario’s government that used a 1987 Ronald Reagan speech criticizing trade duties. The Ronald Reagan Presidential Foundation later condemned the ad’s use of the speech, prompting Trump to allege interference with an upcoming Supreme Court tariff decision and declare that “all trade negotiations with Canada are hereby terminated.” Currently, most Canadian imports face a 35% levy unless exempt under the USMCA or specific sectoral agreements covering autos, lumber, and steel.

In response, Canadian Prime Minister Mark Carney expressed optimism about resuming talks, emphasizing the “progress made” in negotiations. Ontario Premier Doug Ford said the ad campaign would be paused on Monday to allow trade discussions to continue, though the commercials would still air during Toronto’s World Series games. The tariff escalation has already stirred concern among North American logistics providers, who warn of rising cross-border freight costs and potential disruptions in key supply chains between the US and Canada.
