What it is	This program teaches you the science behind how the human body works, how diseases develop, and how medicines treat them. You study human biology, pharmacology, and related medical sciences rather than practising medicine itself. The co-op version includes mandatory work terms at healthcare or research organizations alongside your coursework, letting you test whether this field suits you before committing to further training.	You study physical sciences — chemistry, physics, geology, and environmental topics — with a focus on how they connect to human health and the living world. This stream emphasizes the intersection between earth and life sciences rather than pure physics or chemistry alone. The co-op option lets you do paid work terms at relevant employers alongside your degree. It suits students interested in environmental health, toxicology, or science careers that bridge the natural world and wellness.	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.
