Trump criticized Canada for treating American farmers unfairly with high tariffs on dairy products and labeled Canadian trade representatives as difficult to deal with. The U.S. Lumber Association accused Canada of dumping lumber into the United States, leading to the closure of U.S. lumber mills. Trump declared intentions to impose tariffs on Canadian lumber and dairy products by March 7, alleging that "Canada has been ripping us off for years on tariffs for lumber and dairy products." In reaction, Ottawa halted $125 billion of tariffs on U.S. products scheduled to be implemented on March 25.
