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.	Life Sciences is a broad study of living organisms, their cells, genetics, and chemistry at the molecular level. You'll take core courses in biology, chemistry, and biochemistry, then choose a focus like microbiology, biotechnology, or human biology depending on your interests. The co-op option lets you alternate between school and paid work terms in research labs, hospitals, or biotech companies, giving you real experience alongside your degree.	You study the natural systems that support life on Earth — combining biology, chemistry, geology, and geography to understand ecosystems, environmental problems, and how living things interact with their physical surroundings. This pathway is structured to integrate multiple science disciplines rather than focus narrowly on one, and it includes mandatory co-operative work terms where you apply classroom learning to real environmental jobs. It suits students curious about how nature works across scales, from molecules to landscapes, who want hands-on experience before deciding on a specific environmental career.	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.

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.
