The Iron Ring is a ring worn by many Canadian engineers as a symbol and reminder of the obligations and ethics associated with their profession. The ring is presented in a private ceremony known as the Ritual of the Calling of an Engineer.[1][2] Qualification for the obligation ceremony is either completion of a CEAB accredited engineering program or meeting the academic standard for licensure with a provincial engineering regulator. The concept of the ritual and the rings originated from H. E. T. Haultain in 1922, with assistance from Rudyard Kipling, who crafted the ritual at Haultain's request.[1][3]
