What it is	This program lets you study science by mixing chemistry, physics, and other fields rather than focusing on just one. You design your own pathway through courses across multiple disciplines, so you might combine chemistry with environmental science or physics with biology depending on your interests. It suits students who want flexibility to explore where different sciences connect instead of committing to a single specialization.	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.
