What it is	This program introduces you to how Earth's physical systems — climate, geology, water — interact with human society and geography. You explore environmental challenges through both natural science and social perspectives, rather than focusing on just one. It suits students curious about environmental issues from multiple angles who want hands-on experience through co-op placements.	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.

Ranges are what each university publishes, not guaranteed cutoffs, and limited-enrolment programs often admit above them. Confirm anything you are about to act on with the university; each column links to its source.
