Fundamental Principles Guiding the Profession

The CPA Code of Professional Conduct ("Code”) sets out the principles that guide members, firms, students and applicants in respect of sound and fair financial and management reporting and business practices, and lays out their obligations to clients, employers, colleagues and the public interest.


The CPA Ontario Code of Professional Conduct came into effect on February 26, 2016. The former Rules of Professional Conduct and related Council Interpretations were repealed as of that date.

The Student Code of Conduct came into effect on November 19, 2018. The Student Code was created to set out the principles of professional responsibility that students are required to uphold.
