Out of the options you provided, the organization that has not been a major influence in setting financial reporting standards for Canadian entities is the CRA (Canada Revenue Agency). The CRA primarily focuses on tax administration and enforcement in Canada, rather than setting financial reporting standards. On the other hand, the FASB (Financial Accounting Standards Board), the AcSB (Accounting Standards Board), and the IASB (International Accounting Standards Board) have all played significant roles in establishing financial reporting standards for Canadian entities.
