What it is	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.	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.
