Undergraduate Bachelor of Science (B.Sc.) programs of study

If you are looking for undergraduate Bachelor of Arts & Science (B.A. & Sc.) programs, please consult the B.A. & Sc. website.
If you are looking for information on graduate programs, the Faculty of Science also offers master's (M.Sc.) and doctoral (Ph.D.) degrees.

Things you should know:

What is the difference between Major, Honours, and Liberal programs?

You can choose breadth or depth. For more details, consult our program types webpage.

What can I major in; what groups can I choose from?

B.Sc. students are admitted to a group, such as the Physical, Earth, Math & Computer Science group. You can choose any program from within that group. ("Program" means Major, Liberal Core Science Component, and Honours programs.) For more details about program groups, and applying to Science, please consult this program groups webpage.

What can I minor in?

B.Sc. students may choose any Minor in any group.

Is a minor program optional or required?

B.Sc. Majors and Honours students do not need to complete a second program (such as a minor); it is optional.

B.Sc. Liberal students must combine a core science component (CSC) in one discipline with a second program.  This second program is one of: (1) a minor from a variety of disciplines, or (2) a minor or major concentration from the Faculty of Arts, or (3) a second CSC. Note that a science minor or second CSC can be in any group.
