A major is senior to a captain and junior to a lieutenant-colonel.
The rank insignia in the Canadian Army is a crown.
Majors fill the positions of company/squadron/battery commanders, or deputy commanders of a battalion/regiment; in the Air Force they are typically squadron second-in-command, or commander of a detached helicopter flight embarked onboard Canadian naval vessels.
The naval equivalent rank for major is lieutenant-commander.
