What it is	You study mathematics and economics together as equally important subjects, learning how to use mathematical methods to analyze economic problems and data. This combined degree differs from studying either subject alone because you build expertise in both fields rather than majoring in one and minoring in the other. It suits students who enjoy both abstract mathematics and real-world applications, and want to prepare for careers in finance, data analysis, or economic research.	This program combines environmental science and social justice, exploring how environmental problems affect communities and how policy and activism can address them. You study ecology alongside politics, sociology, and ethics rather than treating environmental issues as purely technical. It suits students who care about the environment but want to understand its human and political dimensions, and the co-op option lets you work in nonprofits, government, or advocacy organizations while you study.	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.
