Professional regulation in Canada is provincial/territorial, so CPD/CED requirements are set and administered by each regulator. NPPE materials commonly note that while most regulators support continuing competence programs, the details vary: some make CPD mandatory, some have different hour/unit structures, categories, or learning activities, some require annual reporting, and some rely on audits/enforcement mechanisms with consequences for non-compliance. That makes C true. A is incorrect because Engineers Canada and Geoscientists Canada do not administer licensure requirements across jurisdictions; they may support guidance and inter-jurisdictional coordination, but CPD rules are not uniformly “strictly voluntary” nationwide. B is not the primary regulatory purpose; regulators focus on public protection and competence assurance rather than “rewards” and public acknowledgements. D is incorrect because CPD/CED is not federally administered in Canada, and rules are not uniform across all jurisdictions. Therefore, C is the correct statement.
