In 2014, Inwood and Johns analyzed the policy legacy of ten Canadian commissions of inquiry. This article extends that analysis by incorporating the policy legacy as one element of the leadership legacy of the commission chairs; the other two elements are the chair’s expressive legacy and fiduciary legacy. The expressive legacy can be that of a conservator, consolidator, entrepreneur, or catalyst, and the fiduciary legacy is determined by the commission chair’s respect for the norms and conventions of commissions of inquiry. Using the case studies from Inwood and Johns’ analysis of the commissions’ policy legacies, we ascribe expressive and fiduciary legacies to the chairs of the ten commissions. Through analysis of the relationships among the commissions’ policy legacies and the chairs’ expressive and fiduciary legacies, we explore the ways in which chairs’ conduct of the inquiry produce a leadership legacy for the chair.
