Canada has imposed retaliatory tariffs of between 15 and 50 percent on roughly $20 billion worth of US imports — including steel, aluminium, dairy, appliances and cosmetics — after US President Donald Trump's 50 percent tariffs on a similar value of Canadian goods took effect on August 22. Prime Minister Mark Carney described the response as a "dollar-for-dollar" measure, accusing Washington of inserting last-minute "uneconomic and unfair" demands that derailed earlier negotiations. The escalating dispute is fuelling a surge of economic nationalism among Canadian consumers, with surveys showing strong majority support for buying domestic products even at higher prices, though economists warn that businesses and households alike face rising costs and potential job losses as the tariff pressures deepen.
