What it is	Engineering I – Discovery Track lets you explore multiple engineering specializations during your first year before committing to a specific stream like chemical, civil, electrical, mechanical, or software engineering. You can also choose to combine engineering with management or social studies. The co-op option means you'll alternate between classroom and paid work terms, giving you real experience in the field while studying.	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 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.
