Established in 1941, The Institute of Internal Auditors (IIA) is an international professional association with global headquarters in Lake Mary, Florida, USA. The IIA is the internal audit profession's global voice, recognized authority, acknowledged leader, chief advocate, and principal educator. Generally, members work in internal auditing, risk management, governance, internal control, information technology audit, education, and security.

Globally, The IIA has more than 200,000 members. The IIA in North America comprises 160 chapters serving more than 70,000 members in the United States, Canada, the Caribbean (Aruba, Bahamas, Barbados, Cayman Islands, Curacao, Jamaica, Puerto Rico, and Turks & Caicos), Bermuda, Guyana, and Trinidad & Tobago.

The Institute of Internal Auditors Canada (The IIA Canada) is affiliated with this global body, serving the needs of more than 7,400 members in Canada. With its headquarters in Ottawa, The IIA Canada works in partnership with its 12 Chapters across the country, providing learning, training, professional development, publications, and services for its members, and advocating for the profession to key governments, regulatory bodies, and related organizations.

The first Canadian IIA Chapter was established in Toronto in 1944. Over the years, Chapters grew in number across the country. In the early 2000’s, Canadian internal audit leaders identified unique needs that were not being met by the IIA North American nor Global organizations. A Canadian Board was established in 2006 to provide a voice for the profession in Canada.

The IIA Canada members continue to enjoy the benefits offered by The IIA North American Service Center including: local, national, and global professional networking; world-class training; certification; standards, and guidance; research; executive development; career opportunities; and more.​
