Canada has enacted retaliatory tariffs on billions of dollars worth of US goods, escalating a trade dispute between the two North American neighbors. This action comes in response to the US imposing its own tariffs on Canadian products.

• The duties range from 15 percent to 50 percent, targeting $27.6 billion (US$20 billion) in imports.
• Key figures involved include US President Donald Trump and Canadian Prime Minister Mark Carney.
• The trade conflict has also seen US President Trump threaten Bombardier Aviation, a Canadian aerospace company.
