Canada implements retaliatory tariffs on US goods, escalating trade dispute

Canada's retaliatory tariffs, ranging from 15% to 50% on billions of dollars' worth of US imports, including steel, aluminum, furniture, and dairy products, have come into effect. This action escalates a trade dispute marked by increasing tensions between Canadian Prime Minister Mark Carney and US President Donald Trump. The tariffs match the dollar value of US exports targeted by earlier US levies.
