What it is	An Honours Science degree lets you study a science subject deeply — biology, chemistry, physics, computer science, or another physical science — and choose your own focus within it. Unlike a general science program, an Honours degree requires a concentrated major and typically includes a research or capstone component. The co-op option means you alternate between school terms and paid work placements in science-related jobs, which suits people who want real workplace experience alongside their degree.	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.	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.
