Accounting regulatory bodies in Canada, such as the Chartered Professional Accountants of Canada (CPA Canada) and provincial regulators like the Chartered Professional Accountants of Ontario (CPA Ontario) and the Autorité des marchés financiers (AMF) in Quebec, serve several important purposes to ensure the integrity and reliability of financial reporting and the accounting profession. These purposes include:

1. Setting Standards: Regulatory bodies establish and maintain accounting and auditing standards that companies and professional accountants must adhere to when preparing and auditing financial statements. These standards ensure consistency, transparency, and accuracy in financial reporting.
2. Protecting Investors and Stakeholders: One of the primary functions of accounting regulatory bodies is to protect the interests of investors, creditors, and other stakeholders by promoting trustworthy and credible financial information. This helps to build trust in the financial markets.
3. Ensuring Professional Competence: Regulatory bodies set education, examination, and continuing professional development requirements for accountants to ensure they are competent and up-to-date with industry best practices. They also enforce ethical standards within the profession.
4. Licensing and Regulation: Regulatory bodies oversee the licensing and regulation of accounting professionals. They establish the criteria for obtaining and maintaining licenses, which are necessary for individuals to offer accounting and auditing services.
5. Enforcement and Discipline: These bodies have the authority to investigate and discipline accountants who violate professional standards or engage in unethical behavior. This includes the power to revoke or suspend licenses or memberships.
6. Public Interest: Accounting regulatory bodies are typically focused on the public interest, aiming to maintain the quality of financial reporting and the integrity of the accounting profession. They work to ensure that financial information is accurate, reliable, and beneficial to the public and the business community.
7. Advocacy and Representation: Regulatory bodies often serve as advocates for the accounting profession in discussions with government agencies, standard-setting bodies, and other stakeholders. They represent the interests of accountants and promote the profession’s role in the economy.
8. Research and Education: These bodies may conduct research and provide educational resources to accountants and the business community, helping them stay current with accounting developments and changes in regulations.
9. Oversight of Audit Quality: In Canada, the regulatory bodies play a role in the oversight of audit quality, which involves monitoring and regulating audit firms to ensure that audits are conducted to high standards.

Overall, the purpose of accounting regulatory bodies in Canada is to create a framework that upholds the quality and ethics of the accounting profession, protects the interests of various stakeholders, and promotes confidence in financial reporting and the Canadian economy.
