Deciding is difficult. So don't.

With so many different sciences to love, why limit yourself? Honours Science at Waterloo lets you keep your interests broad.

Take a range of courses in chemistry, biology, physics, earth sciences, and more in the most flexible program within the Faculty of Science. Because you don’t have to commit to a major, more than half of your courses are electives. Choose additional science courses, or take advantage of offerings from other departments across the university.

Once you graduate, an Honours Science degree gives you an excellent foundation for many science-related careers. It also makes it easy to meet the requirements for professional programs such as medicine, dentistry, optometry, and more.

Choose your own courses

In Waterloo’s most flexible science program, there’s only one restriction: six of your 10 courses each year must be science related. After that, it’s up to you!

Pick your Science major later

If you end up falling in love with a particular subject in Science, you can switch into a more specialized program at any time up to third year.
