What it is	You study chemistry alongside medical and biological sciences, learning how molecules, cells, and chemical processes work in living systems. This combines pure chemistry with applied health science rather than focusing only on one discipline. It suits students interested in understanding the chemical basis of medicine, pharmacology, or biochemistry without committing to a professional health program like medicine.	You study science and business together in one program, combining technical subjects like chemistry or biology with courses in marketing, entrepreneurship, and business strategy. Unlike a regular science degree with a business minor added on, this program integrates both throughout, so you learn how science discoveries become commercial products. The co-op option lets you alternate school terms with paid work placements. This suits students who want a science background but also care about bringing ideas to market or running a company.	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 the natural systems that support life on Earth — combining biology, chemistry, geology, and geography to understand ecosystems, environmental problems, and how living things interact with their physical surroundings. This pathway is structured to integrate multiple science disciplines rather than focus narrowly on one, and it includes mandatory co-operative work terms where you apply classroom learning to real environmental jobs. It suits students curious about how nature works across scales, from molecules to landscapes, who want hands-on experience before deciding on a specific environmental career.
