What it is	You study the natural systems that support life on Earth — combining biology, chemistry, geology, and geography to understand ecosystems, environmental problems, and how living things interact with their physical surroundings. This pathway is structured to integrate multiple science disciplines rather than focus narrowly on one, and it includes mandatory co-operative work terms where you apply classroom learning to real environmental jobs. It suits students curious about how nature works across scales, from molecules to landscapes, who want hands-on experience before deciding on a specific environmental career.	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.	You study physical sciences — chemistry, physics, geology, and environmental topics — with a focus on how they connect to human health and the living world. This stream emphasizes the intersection between earth and life sciences rather than pure physics or chemistry alone. The co-op option lets you do paid work terms at relevant employers alongside your degree. It suits students interested in environmental health, toxicology, or science careers that bridge the natural world and wellness.

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.
