At the moment Canada is currently the US's largest goods trading partner with $632 billion in a two -way goods trade in 2013. Canada and the US have one of the closest relationships in the world! This can been observed in the high amount of trade (more then $2 billion dollars a day in goods and services) and in people-to-people communication.
The United States of America and Canada have one of the closest relationships between two countries ever observed! There has been a huge mingling of people as large numbers move between the countries. One noticeable trend through, is a decrease of people leaving Canada to live in the United States. In 2000 the number was 113,100 and had dropped 73,000 in 2006. That's a 35% decrease!
The United States and Canada are both close in politics. Although they don't share a similar government, with Canada's constitutional monarchy and the US's constitutional republic, they have been allies in war, discussing policies between the two countries (sometimes disagreeing), and keeping alive healthy trade.
