What it is	You study the structure and behaviour of atoms, molecules, and reactions: how substances interact, break down, and transform. Unlike a general science degree, this is a focused program in chemistry alone, and includes a mandatory co-op term where you work in a lab or industry setting. It suits students who enjoy hands-on lab work and want practical experience alongside theory before entering chemistry, materials, or pharmaceutical careers.	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.
