Canada's Carney talked tough on Trump - now some say he's backing downIt's another curveball in the Canada-US trade war - a new missive by US Donald Trump threatening an unexpected 35% tariff on Canadian goods starting next month. But Canada's new prime minister, Mark Carney, is beginning to face questions over whether he is able to stand up to Trump and secure the fair deal for Canada he promised. But Canada's recent concessions to Trump appear to have yielded, to date, little result. Roland Paris, a former adviser to Ottawa on Canada-US relations, told the BBC that it is too early to say whether Canada has conceded things prematurely. "If, in the end, Carney appears to have capitulated to Trump and we're left with a bad deal, he will pay a political price at home," he said.
