What it is	A Science Major is a four-year degree where you study one science subject deeply — such as physics, biology, geology, or environmental science — along with complementary courses in math and other sciences. It differs from a specialized honours program in that you focus on breadth within your chosen field rather than pursuing a single narrow specialization. This program suits students who want solid grounding in a science discipline without committing to professional training like engineering or medicine.	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.	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.
