The North American Free Trade Agreement (NAFTA; Spanish: Tratado de Libre Comercio de América del Norte, TLCAN; French: Accord de libre-échange nord-américain, ALÉNA) is an agreement signed by Canada, Mexico, and the United States, creating a trilateral rules-based trade bloc in North America. The agreement came into force on January 1, 1994. It superseded the Canada–United States Free Trade Agreement between the U.S. and Canada. NAFTA has two supplements: the North American Agreement on Environmental Cooperation (NAAEC) and the North American Agreement on Labor Cooperation (NAALC).
