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.	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.	This program combines foundational study in mathematics with hands-on work in chemistry, physics, astronomy, geology, and related fields. You'll take core courses in pure and applied mathematics alongside lab work and theory in the physical sciences, giving you breadth rather than specialization in a single discipline. It suits students drawn to quantitative problem-solving across multiple scientific areas who want flexibility to explore before committing to a specific path.
