To recognize the diversity of student backgrounds and interests, and the multiple routes to understanding provided by a modern university, the Faculties of Arts and of Science offer a 90-credit multi-track program that includes a major concentration in one faculty complemented by a major concentration in the other faculty (see below):

If students want to study at the honours level in two disciplines, they can combine a joint honours program component from an Arts discipline with one from a Science discipline; see Joint Honours Programs for a list of available programs. Each joint honours component consists of a maximum of 36 required and complementary credits (not including program prerequisites). In cases where a minimum of 24 credits are in courses normally restricted to honours students, the total of required and complementary credits may be as few as 30.

An interfaculty program is an approved selection of courses constituting a concentration in an intellectually coherent and interfaculty field of studies. These courses must include approved selections from the Faculties of Arts and of Science and possibly other faculties. See Interfaculty Programs for a list of approved programs. Students in the B.A. & Sc. who complete an approved interfaculty program must also complete an approved minor concentration or a minor in the Faculties of Arts or of Science. Students must complete at least 21 credits in the Faculty of Arts and at least 21 credits in the Faculty of Science as part of the interfaculty program and the minor concentration or minor program.

Honours programs demand a high degree of specialization and require students to satisfy specific departmental and faculty honours requirements while maintaining good Academic Standing. They are designed to prepare students for graduate study. Students in the B.A. & Sc. who complete an approved honours program must also complete an approved minor concentration or a minor in the Faculties of Arts or of Science. Students must complete at least 21 credits in the Faculty of Arts and at least 21 credits in the Faculty of Science as part of the honours program, minor concentration, or minor program. See Honours Programs for a list of available programs.

To choose the honours option, students must meet the GPA/cGPA requirements set out in University Regulations and Resources > Undergraduate > Graduation > Graduation Honours > Honours and First-Class Honours for Faculties of Arts and Science (including B.A. & Sc.).
