Canada’s retaliatory tariffs ranging from 15 to 50 percent have officially taken effect on nearly $20 billion worth of US imports—including steel, appliances, agricultural gear, and dairy—matching the 50 percent tariffs previously imposed by US President Donald Trump. To protect domestic workers and businesses, Canadian Prime Minister Mark Carney announced a $5.42 billion support package to mitigate the impact of the trade escalation, which has expanded into threats against Canadian manufacturer Bombardier and symbolic spats like Trump renaming Lake Ontario "Lake America." Economists warn that these counter-measures could severely strain US automakers and significantly raise prices on hundreds of consumer goods for American buyers.
