The CPA Western School of Business (CPAWSB) delivers CPA education on behalf of provincial and territorial CPA bodies in Western and Northern Canada. This includes the CPA Professional Education Program (CPA PEP), CPA preparatory courses, Post-Designation Public Accounting, and CPA Reciprocity Examination.
CPAWSB was originally formed in 2000 as the CA School of Business (CASB) by the Alberta, British Columbia, Manitoba, and Saskatchewan Institutes of Chartered Accountants. In 2011, the three main accounting bodies in Canada, representing CAs, CGAs, and CMAs, agreed to replace those designations with the Chartered Professional Accountant (CPA) designation. CASB formally evolved to become CPAWSB in 2015.
