The Canada–Central American Free Trade Agreement was a proposed free trade agreement between Canada and the Central American states of Guatemala, El Salvador, Honduras, and Nicaragua, collectively referred to as the CA4 (Canada already has a bilateral FTA with another Central American country, Costa Rica). Negotiations were undertaken between 2001 and 2010 and included twelves rounds of negotiations, after which time Canada and Honduras instead decided to pursue a bilateral agreement between themselves. Those negotiations concluded successfully in August 2011.
The U.S. has negotiated and ratified a similar treaty with these countries, called the Central American Free Trade Agreement. In a referendum on October 7, 2007, the voters of Costa Rica narrowly backed the free trade agreement with the U.S., with about 52 percent of "Yes" votes.
