What it is	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 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.	You study the natural systems that support life on Earth — combining biology, chemistry, geology, and geography to understand ecosystems, environmental problems, and how living things interact with their physical surroundings. This pathway is structured to integrate multiple science disciplines rather than focus narrowly on one, and it includes mandatory co-operative work terms where you apply classroom learning to real environmental jobs. It suits students curious about how nature works across scales, from molecules to landscapes, who want hands-on experience before deciding on a specific environmental career.
