What it is	A Science Major is a four-year degree where you study one science subject deeply — such as physics, biology, geology, or environmental science — along with complementary courses in math and other sciences. It differs from a specialized honours program in that you focus on breadth within your chosen field rather than pursuing a single narrow specialization. This program suits students who want solid grounding in a science discipline without committing to professional training like engineering or medicine.	You study physical sciences — chemistry, physics, geology, and environmental topics — with a focus on how they connect to human health and the living world. This stream emphasizes the intersection between earth and life sciences rather than pure physics or chemistry alone. The co-op option lets you do paid work terms at relevant employers alongside your degree. It suits students interested in environmental health, toxicology, or science careers that bridge the natural world and wellness.	Environmental Engineering combines math, chemistry, physics, and biology to solve real-world problems like water treatment, air quality, and waste management. Unlike a pure science degree, you learn engineering design and practical problem-solving alongside the science fundamentals. The program includes mandatory co-op work terms, so you gain industry experience while studying. This suits students who want to apply science to environmental challenges and prefer hands-on learning alongside classroom work.
