The correct answer is A . CIRO IDPC Rule 1402 establishes the overarching standards of conduct applicable to Regulated Persons. It requires them to observe high standards of ethics and conduct, act openly and fairly, and follow just and equitable principles of trade. Critically, Rule 1402(1)(ii) states that a Regulated Person “must not engage in any business conduct that is unbecoming” or detrimental to the public interest. Accordingly, conduct that is unbecoming may itself constitute a breach of CIRO's standards.
B and D describe conduct that CIRO expressly requires , rather than prohibits. C is deliberately incorrect because Rule 1402 identifies an unreasonable , not a reasonable, departure from expected standards as conduct that may contravene the rule. Other examples include negligence, failure to comply with legal or regulatory obligations, and behaviour likely to diminish investor confidence in securities or derivatives markets.
This principles-based framework is important because misconduct need not fall within a narrowly defined prohibited transaction to raise a regulatory issue. Approved Persons are expected to exercise professional judgment consistent with ethical standards and market integrity.
The CIRE syllabus specifically requires candidates to understand ethical principles, CIRO standards of conduct, and the ethical and legal responsibilities of Investment Dealers and Approved Persons.
