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.	One Health is the study of how human health, animal health, and the environment are connected, drawing on biology, genetics, microbiology, and veterinary science. Unlike traditional biology or health science programs, it teaches you to see disease and wellness across all three systems rather than in isolation. The co-op option means you alternate between study terms and paid work placements. This suits people interested in public health, disease prevention, food safety, or environmental health who want hands-on experience before graduation.

Ranges are what each university publishes, not guaranteed cutoffs, and limited-enrolment programs often admit above them. Confirm anything you are about to act on with the university; each column links to its source.
