What it is	Environmental Science combines the study of living systems and Earth's physical processes — like climate, water, and soil — to understand how natural environments work and respond to human activity. Unlike a program focused only on biology or only on geology, this degree integrates both to tackle real-world environmental problems. It suits students interested in conservation, resource management, or environmental consulting who want a broad scientific foundation rather than specialization in a single discipline.	Biology is the study of living organisms — from molecules and cells to whole organisms and ecosystems. At University of Ottawa, you focus especially on molecular biology and biochemistry, exploring how life works at the chemical level. You can choose a standard four-year degree or add co-op work terms where you alternate between studying and working in research labs or biotech companies.	Life Sciences at UTM lets you study how living systems work, from the structure of molecules to human health and evolution. You can focus on areas like molecular biology, biotechnology, human biology, or anthropology depending on your interests. The program includes optional co-op work terms that let you gain hands-on experience in labs, hospitals, or research settings alongside your coursework — useful if you're considering health professions or research careers.	Medical Sciences is a four-year undergraduate program where you study human biology, chemistry, and related sciences to prepare for health professions or medical research. Unlike a general science degree, it focuses specifically on the foundational knowledge needed for medicine, dentistry, pharmacy, or graduate health programs. The program includes optional co-op work terms, letting you gain hands-on experience in labs, hospitals, or health settings alongside your coursework. It suits students drawn to understanding how the human body works and considering careers in health care or biomedical fields.
