What it is	Environmental Sciences is a degree combining biology, geology, chemistry, and geography to understand how natural systems work and respond to human activity. The co-op version requires you to complete paid work terms at environmental organizations or research facilities alongside your studies, giving you real-world experience before you graduate. It suits students who want hands-on learning and prefer to test career directions in the field rather than only in classrooms.	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.	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.	Life Sciences is a broad study of how living things work, from individual cells and genetics to whole organisms and ecosystems. You'll choose a focus area like microbiology, human biology, genetics, or plant science, and take courses across biology, chemistry, and related fields. The co-op option lets you alternate study terms with paid work placements in research labs, hospitals, or biotech companies, giving you real experience alongside your degree.
