A Transatlantic Free Trade Area (TAFTA) is a proposal to create a free-trade area covering Europe and North America, on both sides of the Atlantic Ocean. Such proposals have been made since the 1990s and since 2013 an agreement between the United States and the European Union has been under negotiation: the Transatlantic Trade and Investment Partnership. If an agreement is reached and ratified on both sides (which is not certain) then, at least in theory, it could potentially be expanded to include the European Free Trade Association (EFTA). Canada and Mexico each have free trade agreements with both the EU and EFTA.
