The Ontario Athletic Therapist Association (OATA) is the professional association that governs the practice of all Certified Athletic Therapists in the province of Ontario. After having completed an internship comprised of both clinical and field work, a stringent written and practical set of national examinations must also be successfully completed. Canadian Athletic Therapists must participate in a mandatory maintenance of certification program. This ensures that all Athletic Therapists annually demonstrate that they have remained current with the developments in their professional field. Athletic Therapy is one of the very few Canadian health care professions that requires its members to upgrade on an annual basis. The OATA endeavours to ensure that all of its members are offering safe and effective treatment to all of their clients and patients. Continuing education programs, examination preparation courses, publications and participation as a member of the Sports Medicine Council of Ontario are examples of the many initiatives undertaken by the OATA.

The OATA is a recognized chapter of the Canadian Athletic Therapists Association. All professional members of the OATA have passed university or college courses specified by the CATA.
