All provincial and territorial Codes of Ethics mandate that professional members act with integrity, honesty, and competence. This includes the duty to communicate information clearly, accurately, and truthfully. Misrepresenting or obscuring results, regardless of the audience's technical expertise, is a serious ethical breach. Professionals have an obligation to make complex information understandable to non-technical audiences without sacrificing accuracy, as this is crucial for informed decision-making and protecting the public interest.

A. The duty to act with fairness, courtesy, and good faith towards all persons is a standard tenet in all Codes of Ethics.

B. The duty to report illegal or unethical practices is a key component of self-regulation and upholding the profession's integrity.

C. Acting as a faithful agent to an employer or client is a fundamental duty, encompassing confidentiality and conflict of interest avoidance.
