What it is	This program teaches you economic theory and quantitative analysis — how markets work, how people make financial decisions, and how to use data and math to test economic ideas. The co-op requirement means you'll alternate between classroom semesters and paid work terms at companies, government agencies, or research organizations, giving you real-world experience alongside your studies. It suits people who enjoy both math and thinking about how societies allocate resources, and who want to build practical skills before graduation.	Environmental sciences combines biology, chemistry, economics, and Earth systems to understand how environments work and how human activity affects them. The co-op option lets you alternate between study terms and paid work placements with environmental organizations, government agencies, or companies, giving you real experience alongside your degree. This program suits people who want practical skills in environmental problem-solving and prefer learning through both classroom study and workplace application.	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.
