What it is	Biomedical Science is the study of how the human body works at the cellular and molecular level, using tools from biology and chemistry to understand disease and develop treatments. The co-op option requires you to complete paid work terms at labs, hospitals, or research facilities alongside your studies, giving you real experience in the field. This program suits students who want hands-on exposure to medical science before deciding whether to pursue medicine, dentistry, or research careers.	You study how the natural world works alongside the human systems that affect it. The BES focuses on environmental policy, conservation, and sustainability through social and geographic lenses, while the BSc emphasizes the physical science side: geology, ecology, and environmental processes. Both paths suit people interested in solving real environmental problems through either policy and community work or scientific research and analysis.	You study chemistry, physics, astronomy, or geology at an advanced level, choosing your focus after first year. This program includes a co-op option that lets you work for employers in research, industry, or government between school terms. It suits students who are curious about how matter, energy, and natural systems work and want both hands-on lab experience and real-world work placements.
