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.	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.	This program combines science study with teacher education, so you earn qualifications to teach science in secondary school while completing your degree. Unlike a regular science degree followed by teacher training, you work toward both goals at the same time, with coursework in science disciplines alongside education theory and practice teaching. It suits students who know they want to teach and want to study science deeply rather than broadly.

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.
