What it is	This is a first-year science program that teaches you foundational chemistry, physics, and related subjects before you specialize. Unlike going directly into a single honours program, you spend your first year exploring different branches of physical science, then choose your final degree path — either a pure science degree or a combined science and engineering degree. It suits students who are strong in math and science but aren't yet sure whether they want to focus purely on theory or blend science with applied engineering.	Environmental Geoscience is the study of Earth's physical systems — rocks, landforms, water, and climate — combined with how human activity affects and depends on the environment. It differs from pure geology because it emphasizes the interactions between natural processes and people, drawing on geography and environmental science alongside earth science. It suits students curious about how landscapes form and change, and interested in solving real-world problems like pollution, resource management, or climate impacts.	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.
