What it is	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.	A Science Major is a four-year degree where you study one science subject deeply — such as physics, biology, geology, or environmental science — along with complementary courses in math and other sciences. It differs from a specialized honours program in that you focus on breadth within your chosen field rather than pursuing a single narrow specialization. This program suits students who want solid grounding in a science discipline without committing to professional training like engineering or medicine.	You study the science of living systems — cells, organisms, genetics, and disease — with flexible depth depending on which specialization you choose. The co-op option lets you alternate between classroom semesters and paid work terms at research labs, hospitals, or biotech companies, building real experience alongside your degree. This stream suits students drawn to biology and chemistry who want either a traditional path or the chance to test careers in health and life sciences before graduating.
