| Reverse description | An homage to Canada’s engineers, the reverse is a representation of a century of engineering innovation and achievements. The diverse field is represented by (clockwise from top): a computer screen with a robotic hand, set against an AI-inspired dot design; a wire gauge; the chemical diagram for insulin partially shown; a test tube and dropper; a hand holding a pencil; a spur gear next to a compass and the tip of a protractor; a soldering iron; and a computer chip. In the centre, the word “CANADA” appears in blueprint lettering, along with the double dates “1925-2025” commemorating the 100th anniversary (“1925-2025”) of the Calling of an Engineer—a rite of passage for Canada’s engineering graduates. The raised rim is uniquely shaped to resemble the Iron Ring worn by Canadian engineers as a symbol of professional obligation. |
