||Canadian Navy 5th Maritime Operations Group, badge (insignia)|
Gules four bendlets reversed wavy Azure a sea Cerberus Or gorged of a collar Sable garnished Argent holding under the dexter arm a trident Or fesswise;
Motto: STRENGTH IN DIVERSITY;
Symbolism: The field represents the naval environment. Its colours have a double meaning; the first is the various waters in which the Group's elements are operating: blue for the deep waters where submarines and Naval Control of Shipping operate, and red for the littoral waters where Harbour Defence, Divers and Maritime Coastal Defence Vessels operate. The second meaning is the bilingual aspect of the Group's elements and personnel. In Greek and Roman mythologies, Cerberus is the three-headed dog guarding the underworld. This monster represents the Group's main mission to guard the East Coast of Canada. It has been transformed into a sea monster to better represent the naval aspect of the Group.
