What it is	You study how the natural world works alongside the human systems that affect it. The BES focuses on environmental policy, conservation, and sustainability through social and geographic lenses, while the BSc emphasizes the physical science side: geology, ecology, and environmental processes. Both paths suit people interested in solving real environmental problems through either policy and community work or scientific research and analysis.	A Science Major is a four-year degree where you study one science subject deeply — such as physics, biology, geology, or environmental science — along with complementary courses in math and other sciences. It differs from a specialized honours program in that you focus on breadth within your chosen field rather than pursuing a single narrow specialization. This program suits students who want solid grounding in a science discipline without committing to professional training like engineering or medicine.	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 how Earth's climate and environment work, using chemistry, physics, and geography to understand weather systems, ecosystems, and human impacts. This program combines natural science with social geography, so you examine both the physical causes of environmental change and how people and communities respond to it. It suits students curious about climate science who want hands-on experience through co-op placements alongside their coursework.

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.
