US President Donald Trump said he will raise tariffs on Canadian goods by an additional 10%, blasting an Ontario government ad that uses Ronald Reagan's words on tariffs as a "fraud." The move follows Trump's withdrawal from talks with Canada and his claim the ad sought to sway a forthcoming US Supreme Court case on tariffs. Ontario Premier Doug Ford paused the ad campaign after consulting Prime Minister Mark Carney but let it run during World Series games featuring the Toronto Blue Jays. The Reagan Foundation criticized the spot, as Ford and California's Gavin Newsom traded tariff jokes online.
