What it is	A Chemistry degree teaches you the theory and practice of how substances interact, break down, and combine. You'll study pure chemistry alongside molecular biology and biochemistry, giving you a broader foundation than a straight chemistry program. The co-op option lets you alternate between classroom semesters and paid work terms at companies, so you can test whether lab or industrial chemistry work suits you before graduating.	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.	You study physical sciences — chemistry, physics, geology, and environmental topics — with a focus on how they connect to human health and the living world. This stream emphasizes the intersection between earth and life sciences rather than pure physics or chemistry alone. The co-op option lets you do paid work terms at relevant employers alongside your degree. It suits students interested in environmental health, toxicology, or science careers that bridge the natural world and wellness.

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.
