What it is	This is a four-year science degree where you specialize in one of many fields — from chemistry and physics to biology, geology, audiology, linguistics, or environmental science. The honours designation means you go deeper into your chosen subject than a general science degree would. The program includes optional co-op work terms, letting you gain paid professional experience alongside your studies, which suits students who want both classroom learning and real workplace practice in their field.	This five-year program combines biotechnology and chemical engineering, so you study both how to manipulate living systems at the molecular level and how to design and scale up chemical processes. Unlike a straight biochemistry degree, you learn practical engineering skills for industrial production and apply them through mandatory co-op work terms. It suits students who want to bridge pure science and hands-on problem-solving in fields like pharmaceuticals, food processing, or biofuels.	A Bachelor of Science (General) lets you study science broadly across biology, chemistry, environmental science, and related fields, choosing your own mix of courses rather than specializing deeply in one area. Unlike an honours program, it gives you flexibility to explore multiple sciences without committing to a single major or meeting the tighter requirements of a specialized stream. This suits students who are curious about science in general but aren't yet sure which direction appeals to them most.	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.
