Although the practice of academic advising in North America has existed since the colonial era, it is only within the past century that an organized movement to shape the field has taken root. Most of the literature seeking to clarify the role, purpose, and function of academic advising is restricted to the United States. The purpose of this multiple case study was to explore academic advising practices at four Ontario higher education institutions in terms of types of advising, institutional advising model, and roles and responsibilities of advisors. Through document analysis and interviews with advising personnel at four Ontario institutions, our analysis illuminates the state of academic advising in Ontario and offers recommendations for practice.
