Military and peacekeeping

Alongside many domestic obligations, more than 3,000 Canadian Armed Forces (CAF) personnel are deployed in multiple foreign military operations. The Canadian unified forces comprise the Royal Canadian Navy, Canadian Army, and Royal Canadian Air Force. The nation employs a professional, volunteer force of approximately 68,000 active personnel and 27,000 reserve personnel—increasing to 71,500 and 30,000 respectively under "Strong, Secure, Engaged" —with a sub-component of approximately 5,000 Canadian Rangers. In 2022, Canada's military expenditure totalled approximately $26.9 billion, or around 1.2 percent of the country's gross domestic product (GDP) – placing it 14th for military expenditure by country.

Canada's role in developing peacekeeping and its participation in major peacekeeping initiatives during the 20th century has played a major role in its positive global image. Peacekeeping is deeply embedded in Canadian culture and a distinguishing feature that Canadians feel sets their foreign policy apart from the United States. Canada has long been reluctant to participate in military operations that are not sanctioned by the United Nations, such as the Vietnam War or the 2003 invasion of Iraq. Since the 21st century, Canadian direct participation in UN peacekeeping efforts has greatly declined. The large decrease was a result of Canada directing its participation to UN-sanctioned military operations through NATO, rather than directly through the UN. The change to participation via NATO has resulted in a shift towards more militarized and deadly missions rather than traditional peacekeeping duties.
