What it is	You study computer science — writing code, building software, and solving problems with computers — while working in paid job placements throughout your degree. The co-op requirement means you'll alternate between semesters of classes and semesters working at real companies, giving you professional experience alongside your education. The Management option adds business and organizational courses if you want to move toward leadership roles; the straight Computer Science path suits you if you want to focus purely on technical skills and software development.	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.	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 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.
