What it is	You study how to design systems and structures that protect the environment and manage natural resources — combining biology, chemistry, civil engineering, and earth science. Unlike a general engineering program, this one focuses specifically on water treatment, waste management, air quality, and land remediation. It suits students who want to solve real environmental problems with engineering tools and are willing to do mandatory work terms alongside their studies.	You study how to extract useful patterns and insights from large datasets by combining computer science and mathematics. Unlike a standalone computer science or math degree, you learn to write code, build algorithms, and apply statistical and mathematical theory specifically to solve data problems. This program suits you if you want technical depth in multiple areas and are willing to do paid work terms alongside your classes over five years.	You study computer science and mathematics together over five years, learning how to write code, analyse data, and solve problems using mathematical theory and statistical methods. Unlike a single major, this double degree gives you depth in both fields so you can build algorithms and understand the theory behind them. It suits people who want flexibility between pure mathematics and applied programming, and who value alternating work terms with their studies.
