Canada hits back with counter-tariffs as U.S. adds last-minute conditions

Canada announced dollar-for-dollar counter-tariffs on hundreds of U.S. products Tuesday after President Donald Trump's 50 percent tariffs on roughly $28 billion of Canadian goods took effect, escalating the trade war between the two nations. The White House released a statement accusing Canada of trade abuses, while Trump suggested on CNN that the U.S. added new conditions at the 11th hour of negotiations. Prime Minister Mark Carney rejected the deal, calling the last-minute changes "unfair" and "uneconomic." Ontario Premier Doug Ford confirmed he advised Carney against accepting the offer. Trump also floated renaming Lake Ontario to "Lake America" in social media posts, drawing backlash from Canadian officials and prompting a Toronto mayoral candidate to propose renaming New York state. Canada's counter-tariffs take effect Sept. 8, with a $7.5-billion support package for affected workers and businesses.
