What it is	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.	This is a four-year science degree where you specialize in one of many fields — from chemistry and physics to biology, geology, audiology, linguistics, or environmental science. The honours designation means you go deeper into your chosen subject than a general science degree would. The program includes optional co-op work terms, letting you gain paid professional experience alongside your studies, which suits students who want both classroom learning and real workplace practice in their field.	You study chemistry, physics, astronomy, or geology at an advanced level, choosing your focus after first year. This program includes a co-op option that lets you work for employers in research, industry, or government between school terms. It suits students who are curious about how matter, energy, and natural systems work and want both hands-on lab experience and real-world work placements.
