What it is	You study how human activity shapes the natural world and how to address environmental problems through science, policy, and social change. This program combines natural sciences like biology and chemistry with social science perspectives, rather than focusing only on the pure science side. It suits students curious about climate, conservation, and sustainability who want flexibility to explore both the science and the policy angles.	Water Science combines biology, chemistry, physics, and geography to study how water systems work and how to protect them. You'll examine lakes, rivers, and groundwater from ecological and physical angles rather than focusing only on engineering solutions. This program suits students interested in environmental problems who want a science-based approach grounded in both living systems and earth processes.	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.	You study chemistry, physics, astronomy, or geology at an advanced level, choosing your focus after first year. This program includes a co-op option that lets you work for employers in research, industry, or government between school terms. It suits students who are curious about how matter, energy, and natural systems work and want both hands-on lab experience and real-world work placements.

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.
