NAFTA, or the North America Free Trade Agreement, is a trade pact signed by the U.S., Mexico and Canada in 1992. This pact came into effect in 1994,  making it the world's biggest free-trade area. It required the elimination of every trade barrier between the signers for fifteen years. It also included agreements on the environment and labor. This gave Canadian and U.S. companies access to Mexican markets.
