In order for a corporation to practice engineering or geoscience.

In most associations, for a corporation to practice engineering or geoscience, it is required to obtain and maintain a Permit to Practice (Certificate of Authorization). This permit is mandatory as it signifies that the corporation meets the regulatory standards set forth by the professional association and is authorized to provide engineering or geoscience services to the public. This requirement ensures that corporations engage in professional practices that are regulated, maintaining the integrity and safety standards of the profession​​.
