What it is	Environmental Science is the study of how living things, ecosystems, and physical systems like weather and geology interact with human activity. You'll combine biology, chemistry, geography, and environmental policy to understand problems like pollution, climate change, and resource management. The co-op option lets you do paid work terms at environmental organizations or agencies alongside your studies, giving you real workplace experience before you graduate.	You study the science and management of forests, learning about tree biology, ecosystem health, soil, and sustainable harvesting practices. The co-op option lets you work for forestry companies or government agencies during your degree, giving you real workplace experience alongside your coursework. This program suits students who want hands-on work with forests and ecosystems rather than purely classroom-based environmental study.	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.
