Iron Ring
The Iron Ring is worn by Canadian-trained engineers on the little finger of their primary working hand as a symbol and reminder of the obligations and ethics associated with their profession. The ring, which reflects the moral, ethical and professional commitment made by the engineer who wears it, is presented to expected graduates in a private event known as The Ritual of the Calling of an Engineer.
