President Donald Trump said Canada’s and Mexico’s pledges to boost border security to stop illegal drugs were insufficient to keep his tariffs on hold. President Donald Trump said Sunday that Mexico’s and Canada’s actions to stave off his steep tariffs are not sufficient.

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 The agreement was abolished in 2001, but by then NAFTA had more or less superseded it.

Canadian Prime Minister Justin Trudeau announced that Canada would respond with 25% tariffs "against $155 billion worth of American goods."
