Canada’s retaliatory tariffs on a range of U.S. goods take effect on Tuesday, extending an ongoing trade dispute between the North American neighbors. Multiple outlets report that the measures apply to billions of dollars’ worth of products and begin impacting imports from the United States.

The coverage describes the tariffs as “dollar for dollar” levies, with rates reported as ranging from 15% to 50%. CBS News and other outlets name specific affected items including dairy products such as milk and cream, as well as goods like perfume and golf clubs, alongside industrial and trade-sensitive products such as steel and aluminum, paper, and agricultural equipment.

Several sources place the action in the context of recent escalation by U.S. President Donald Trump. France 24 adds that Trump had threatened to block U.S. sales of Bombardier Aviation unless the Quebec-based aircraft manufacturer moves more production to the United States, highlighting the tit-for-tat nature of the measures. The outlets differ mainly in the level of detail about specific categories and the quoted background events, but they broadly agree on the tariff kickoff and the scope of goods covered.
