What it is	Chemical biology combines chemistry and biology to study how molecules work inside living things — particularly how drugs and other chemical compounds interact with cells and organisms. The BSc&Mgt option adds business and management courses alongside the science, useful if you're interested in the commercial or leadership side of biotech companies. This program suits you if you enjoy both chemistry and biology equally and want to understand life processes at the molecular level, or if you're considering roles beyond pure research.	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.	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.
