Free trade is deeply rooted within North America’s agricultural economy. Canada, Mexico, and the United States gradually removed thousands of barriers to regional agricultural trade from 1994 to 2008 as part of the North American Free Trade Agreement (NAFTA). From 1989 to 1993, Canada and the United States pursued agricultural trade liberalization through the Canada-U.S. Free Trade Agreement (CUSTA), which was then folded into NAFTA. Mexico also implemented a number of unilateral agricultural trade reforms in the early 1990s. When these initiatives are considered together, the NAFTA countries have completed a remarkable two decades of agricultural trade liberalization.
