Who We Are

The 4th Canadian Division (4 Cdn Div) is one of the five major formations that report to Army headquarters in Ottawa. 4 Cdn Div is responsible to provide combat ready land forces in accordance with assigned tasks, conduct general purpose training in preparation for various land operations, and provide support services to other organizations as directed or as mutually arranged.
