In some cases this has led to the increasing employment of non-full-time university instructors, and questions have been raised, especially in the United States, concerning the working conditions of part-time faculty and the implications of these changes on educational quality. [...] We then discuss the design of the study, followed by the presentation and analysis of data related to each of the four questions. [...] The number of tenure-stream faculty members employed by Ontario universities is presented in Figure 2. It is clear that the total number of tenure-stream faculty members has gone up and down during the 21-year period captured in the table, with increases in the faculty complement during the early 1990s and decreases in the mid-1990s. [...] There has been little research on part-time faculty or how changes in the academic workforce are impacting the quality of the student experience, the balance of teaching and research activities within the institution, or the culture of academic units (Jones, 2013; Muzzin, 2009). [...] In the case of the University of Toronto, teaching appointments involving contracts of less than one year are covered by the Canadian Union of Public Employees (CUPE) local, while appointments of one year or more (even if they are part-time) are represented by the University of Toronto Faculty Association.
