What it is	This is a first-year science program that teaches you foundational chemistry, physics, and related subjects before you specialize. Unlike going directly into a single honours program, you spend your first year exploring different branches of physical science, then choose your final degree path — either a pure science degree or a combined science and engineering degree. It suits students who are strong in math and science but aren't yet sure whether they want to focus purely on theory or blend science with applied engineering.	This is a broad science degree where you choose from fields like biology, chemistry, physics, computer science, geology, and others. You take foundational science courses in first year, then specialize by selecting which science subjects to focus on. Co-op is available, letting you do paid work terms at science-related employers alongside your studies.	This program covers the study of living organisms and human behaviour, from genetics and microbiology to ecology, nutrition, and psychology. You'll choose a focus area like biological sciences, animal science, environmental studies, or psychology, and take courses that build on that specialization. The co-op option lets you alternate between classroom study and paid work in research labs, hospitals, or environmental organizations. It suits students curious about how life works at every scale, from cells to ecosystems to minds, and who want hands-on experience alongside theory.
