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.	You study the science of living systems — cells, organisms, genetics, and disease — with flexible depth depending on which specialization you choose. The co-op option lets you alternate between classroom semesters and paid work terms at research labs, hospitals, or biotech companies, building real experience alongside your degree. This stream suits students drawn to biology and chemistry who want either a traditional path or the chance to test careers in health and life sciences before graduating.	You study the science of living things — from individual cells and genes to entire ecosystems and animal behaviour. The Environmental Science degree focuses on how organisms interact with their environment, while other options let you specialize in animal biology, plants, genetics, or microbiology. This program suits people curious about how life works and interested in careers ranging from conservation and wildlife management to research, teaching, or health sciences.

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.
