Canada has announced it will match US tariffs 'dollar for dollar' after trade talks between the two countries broke down. The US had imposed new tariffs on Canadian goods, and Canada will impose reciprocal tariffs on US goods. The breakdown in talks has put the US-Canada relationship in uncharted territory and will be a major test for Canada's government. The tariffs will affect a range of goods, including wine, dairy, cement, clothing, and hockey equipment.
