The Coat of Arms of the Challoner Club is that of Bishop Challoner himself. After whom the Club is named.

The Club’s unique expression of these arms was designed especially for the revived Challoner Club by the Very Reverend Robert Bengry, a Canadian Catholic priest and heraldic artist belonging to the Personal Ordinariate of the Chair of Saint Peter, of which he served as Dean of the Deanery of Saint John the Baptist (which oversees all parishes of the Ordinariate in Canada.)
