What it is	This is a broad science degree where you choose from fields like biology, chemistry, physics, computer science, geology, and others. You take foundational science courses in first year, then specialize by selecting which science subjects to focus on. Co-op is available, letting you do paid work terms at science-related employers alongside your studies.	An Honours Mathematics degree means you study pure and applied mathematics at depth over four years, with required courses in calculus, algebra, analysis, and proof-based theory. Unlike a general math program, this honours stream demands rigorous mathematical reasoning and includes optional specializations through electives in computer science, physics, statistics, or economics. It suits students who enjoy abstract problem-solving and want a foundation for graduate studies or technical careers.	This pathway lets you study the fundamental sciences — physics, chemistry, astronomy, mathematics, and biology — together rather than committing to a single discipline right away. You'll take core courses across all these fields in your first year, then gradually specialize based on your interests. The included co-op option means you'll do work terms in research labs or industry, giving you hands-on experience alongside your coursework.
