What it is	You study pure and applied mathematics along with statistics, learning how to solve problems using mathematical reasoning and data analysis. Unlike a straight math degree, you can choose to do co-op, which means you work at paid internships in industry or research between study terms. This suits people who want flexibility in their career path and value real-world experience alongside theory.	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.	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.
