St. Thomas values student-centred learning and has been at the forefront in the development of interdisciplinary majors and electives that allow students to pursue a topic or theme of particular interest. 

The Interdisciplinary major/honours option allows students to tailor a programme to their interests and goals. These programmes focus attention on emerging issues and explore such common themes as Canadian Studies, American Studies, International Relations, Social Justice. They draw upon courses offered by a number of different university departments.
