What it is	This program combines science courses with business studies, so you study both scientific subjects like chemistry, biology, or computer science alongside accounting, management, and economics. Unlike a straight science degree, you gain practical knowledge of how science-based industries operate and how to manage projects or companies. It suits students who want a science career but also care about the business side — whether that's starting a science company, managing research teams, or working in science-related industries.	This is a first-year science program that teaches you foundational chemistry, physics, and related subjects before you specialize. Unlike going directly into a single honours program, you spend your first year exploring different branches of physical science, then choose your final degree path — either a pure science degree or a combined science and engineering degree. It suits students who are strong in math and science but aren't yet sure whether they want to focus purely on theory or blend science with applied engineering.	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.
