What it is	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.	A Bachelor of Arts and Sciences lets you combine study in both humanities and natural sciences within one degree. Unlike most programs that require you to choose either arts or sciences, this one lets you take courses across both — for instance, pairing creative writing with chemistry, or anthropology with animal science. It suits people who are curious across multiple disciplines and want flexibility rather than specializing narrowly from the start.	You study psychology combined with applied health sciences — how human behaviour, biology, and social factors shape health and illness. Unlike a straight psychology program, this stream emphasizes practical health applications and the ability to work across healthcare and social systems. The co-op option lets you work in healthcare settings, clinics, or community agencies while studying. It suits students interested in both understanding the mind and applying that knowledge to real health problems.	This program combines arts courses — drawn from fields like English, history, economics, and creative writing — with business studies to prepare you for careers that value both analytical and communication skills. The co-op option lets you alternate study terms with paid work placements at real companies, giving you experience before you graduate. It suits students who want a broader education than straight business but need practical skills for the job market.
