Through its audits and recommendations, Canada's Office of the Auditor General (OAG) has promoted financial probity and good governance for over a century. While the OAG's recommendations may possess an inherent value, their full value is realized only through their implementation by government. By investigating OAG recommendation implementation rates, and the OAG's interaction with Parliament, this thesis evaluates recent performance at the OAG.Two research questions are considered: first, has OAG performance changed since 1993; and second, have its interactions with Parliament and government changed over the same period?
