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.	A Science Non-Honours degree lets you study physical sciences — chemistry, geology, and related fields — without committing to a specialized honours stream. You complete a three-year program with broader course choices and fewer upper-level requirements than an honours degree, giving you flexibility to explore different areas before specializing or applying to professional programs. This suits students who want a solid science foundation, aren't sure which specialization to pursue, or plan to move into medicine, health sciences, or graduate study.	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.	You study chemistry, physics, astronomy, or geology at an advanced level, choosing your focus after first year. This program includes a co-op option that lets you work for employers in research, industry, or government between school terms. It suits students who are curious about how matter, energy, and natural systems work and want both hands-on lab experience and real-world work placements.
