The Globe and Mail reports in its Friday edition that Canada may impose retaliatory tariffs on the United States if the White House pursues new trade actions, Prime Minister Mark Carney said Thursday. A triple-bylined item led by Marieke Walsh reports that Mr. Carney's priority with the United States is an exhaustive trade deal that leaves no Canadian sector out in the cold. The PM said Ottawa is "in pursuit of a comprehensive agreement that addresses all tariff-related sectors. Everything's on the table if there's no agreement." He was mum on potential retaliation details. Mr. Carney noted that Canada has opted not to pursue partial deals, aiming instead for a comprehensive trade pact to address tariffs on Canadian industries. On Monday, President Donald Trump announced that his administration would impose a 50-per-cent tariff on a wide range of Canadian goods beginning Aug. 19. Mr. Carney said the move from the White House was both a pressure tactic and an opportunity to wrap negotiations that have dragged on for well over a year. "We've seen a series of trade negotiations that the U.S. has undertaken, and normally there's a deadline, normally there's an outsized tariff associated with that deadline," Mr. Carney said.
