What it is	This is a four-year science degree where you specialize in one of many fields — from chemistry and physics to biology, geology, audiology, linguistics, or environmental science. The honours designation means you go deeper into your chosen subject than a general science degree would. The program includes optional co-op work terms, letting you gain paid professional experience alongside your studies, which suits students who want both classroom learning and real workplace practice in their field.	Medical Sciences is a four-year undergraduate program where you study human biology, chemistry, and related sciences to prepare for health professions or medical research. Unlike a general science degree, it focuses specifically on the foundational knowledge needed for medicine, dentistry, pharmacy, or graduate health programs. The program includes optional co-op work terms, letting you gain hands-on experience in labs, hospitals, or health settings alongside your coursework. It suits students drawn to understanding how the human body works and considering careers in health care or biomedical fields.	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.
