The correct answer is D. CCIR's official published mandate is to facilitate and promote an efficient and effective insurance regulatory system in Canada to serve the public interest. That wording appears directly on CCIR's official website and in its published FAQ material.

This makes A incorrect because CCIR is not a public education body focused specifically on Ontario auto and homeowners policies. B is incorrect because CCIR does not directly regulate insurer coverage and premiums in Ontario; those matters are dealt with through provincial and territorial regulators and legal frameworks, such as FSRA in Ontario. C is also not the best answer because, while fair treatment of consumers is an important regulatory objective, that is not the formal wording of CCIR's mandate. CCIR's more recent strategic plan describes the organization as a forum for Canadian insurance regulators that works to strengthen regulatory oversight, but the exam-style question is asking for the specific mandate statement, which matches D exactly.

From a RIBO study perspective, the takeaway is that CCIR is a national coordinating body for insurance regulators, not a single-jurisdiction regulator. Its role is to support regulatory consistency, collaboration, and public-interest oversight across Canada.
