The original coat of arms of the city of St. Catharines has become obscure with age; no information on who commissioned the arms, nor any information on who designed it, is available. Although the heraldic coat of arms is officially registered as a figure of St. Catharines, it is now rarely used as an identifying feature of the city, and has since been supplanted by the city logo. The heraldic coat of arms is, however, used on the city flag.
