HMCS D'Iberville

Argent issuant from a base wavy Azure charged with two bars wavy Argent, a bridge of three arches embattled proper within the dexter arch a rose Gules slipped proper, within the sinister arch a fleur-de-lis Azure, and resting upon the bridge an escutcheon of the Arms of Pierre LeMoyne d’Iberville (Azure three roses Or, on a chief Gules a crescent between two mullets Or);

The escutcheon displays the arms of d’Iberville, after whom the ship was named. The other devices represent the role the ship has played as a bridge between Canada’s two official languages in the context of life at sea and in the navy. The red rose stands for the English language and the blue fleur-de-lis, the French language. The battlements of the bridge refer to defence, and the heraldic representation of water suggests a nautical foundation.
