Canada and Mexico has a trade agreement called the USMCA, it replaced the original NAFTA agreement which was about 20 years old.
The USMCA, short for the United States-Mexico-Canada Agreement, is a trade agreement between the United States, Mexico, and Canada that entered into force on July 1, 2020. It replaced the North American Free Trade Agreement (NAFTA). The USMCA aims to create a more balanced and reciprocal trade environment, supporting North American workers, farmers, ranchers, and businesses.
Trump loved the agreement in 2020 https://trumpwhitehouse.archives.gov/briefings-statements/remarks-president-trump-usmca-celebration-american-workers-warren-mi/
The USMCA is the fairest, most balanced, and beneficial trade agreement we have ever signed into law. It’s the best agreement we’ve ever made, and we have others coming. And, by the way, the China deal, two weeks ago, was just signed. And that’s going to bring $250 billion into our country. (Applause.) One after another.
This year he voided the USMCA agreement bitcching about how unfair it was.
