This study analyzes the professional commitment of Canadian Chartered Accountants who are partners, managers (supervisors) and other staff CAs in public practice. This commitment is examined in relation to organizational commitment, professional-organizational conflict, satisfaction with income and organizational level. The commitment to organization is shown to be the most powerful predictor of CAs' professional commitment in all organizational levels. At the same time, professional-organizational conflict has a negative impact on professional commitment, and satisfaction with income has a positive influence on such a commitment.
