What it is	You study how to run and launch businesses while learning environmental science and sustainability principles. This combines business skills with ecological knowledge, so you understand both profit and environmental impact. The co-op requirement means you alternate between classroom and paid work terms, giving you real workplace experience in green business and sustainability roles. It suits people who want to work in business but care about environmental problems.	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.	A Bachelor of Science Honours is a four-year degree where you specialize in one science discipline — such as biology, chemistry, environmental studies, or nutrition — and take supporting courses in math and other sciences. The honours designation means you complete a research project or thesis in your final year. Many students choose the optional co-op stream, which alternates study terms with paid work placements in related fields, giving you practical experience alongside classroom learning. This program suits students who want depth in a single science and are interested in research, lab work, or professional roles in health, environment, or industry.
