The Obameter: Tracking Obama's Campaign Promises

February/09 Canada and the United States are the world's largest trading partners, with $560 billion US of two way trade in 2007.

About 40 per cent of Canada's annual economic output is exported to the United States, while Canada is the leading export market for 36 of 50 U.S. states.

About seven million U.S. jobs depend on U.S. trade with Canada.

Rising protectionism would hurt both countries, economists say.
