President Donald Trump’s threatened tariffs against Canada and Mexico — now on hold for a month — risked blowing up North America’s economy. What did the United States get out of his deals to pause the import taxes against the two nations?

In 1965, the Canada–United States Automotive Products Agreement was enacted, a precursor to NAFTA that removed tariffs between the two countries. This led to increased auto manufacturing in Canada and more jobs. The agreement was abolished in 2001, but by then NAFTA had more or less superseded it.
