The OAA regulates individuals and legal entities involved in the practice of architecture in Ontario.  A Certificate of Practice must be obtained in order to practise architecture in Ontario and offer professional services to the public. In order to apply for a Certificate of Practice, one must be an architect in good standing with the OAA.  It is also important to note that all architecture practices must also hold professional liability insurance, comply with applicable OAA Bylaws and Rules, and participate in the OAA Practice Consultation Services review program.
