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. It includes all Regular and Reserve Force units in Ontario, with the exception of a portion of North Western Ontario, which falls under 3rd Canadian Division (3 Cdn Div).
The mission of 4 Cdn Div is to generate and maintain, at designated states of readiness, combat ready, multi-purpose land forces to meet Canada’s defence objectives, both at home and abroad. Members of 4 Cdn Div take part in continuous, challenging, individual and collective training to prepare them to achieve this mission.
