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.	Physical & Environmental Sciences is a degree where you study the natural world through disciplines like physics, chemistry, geology, astronomy, and environmental science. You choose which areas to focus on based on your interests. The co-op option lets you alternate study with paid work terms in science-related workplaces, giving you real experience alongside your classes. This program suits students who want to understand how Earth and space work and prefer hands-on learning combined with classroom study.
