In 2011, Canada's military expenditure totalled approximately C$24.5 billion.
Canada and the United States share the world's longest undefended border, co-operate on military campaigns and exercises, and are each other's largest trading partner.

Canada has since served in 50 peacekeeping missions, including every UN peacekeeping effort until 1989, and has since maintained forces in international missions in Rwanda, the former Yugoslavia, and elsewhere; Canada has sometimes faced controversy over its involvement in foreign countries, notably in the 1993 Somalia Affair.
