What it is	This is a four-year science degree focused on understanding natural systems and how human activity affects them. You study biology, chemistry, ecology, and earth science together rather than picking one specialty. It suits students who want a broad grounding in environmental problem-solving and are comfortable with lab work and field studies.	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.	A Biology degree at Glendon lets you study how living things work, from cells and molecules to whole organisms and ecosystems. You'll take core biology courses and choose from specialized areas like genetics, microbiology, human biology, or biotechnology. The iBSc variant integrates bilingual (English–French) instruction throughout your degree, rather than offering biology taught only in English.
