Symbolizing the engineer’s duty to maintain the highest ethical standards and to serve society with integrity, honesty and expertise.

Ritual of the Calling of an Engineer

To foster ethical conduct as a lifelong obligation for engineers educated in Canada.

Dating back to 1922, the Ritual is administered by a body called The Corporation of the Seven Wardens Inc. The Corporation is responsible for administering and maintaining the Ritual and is organized into 28 regional branches, called camps, numbered by order of establishment.

The Ritual of the Calling of an Engineer directs newly qualified Canadian engineers toward a consciousness of their profession.

The idea of a ceremony for the Obligation of Canadian Engineers dates back to 1922.

The ritual, which is administered by the Corporation of the Seven Wardens Inc., also indicates to more experienced engineers their responsibilities in welcoming and supporting newer engineers.

The Obligation Ceremony is not connected to any other engineering organization nor to any university, although many of them support the idea of the Obligation and may participate in the administration of the ceremonies.
