What it is	Environmental Science is the study of how natural systems — including geology, weather patterns, and ecosystems — work and how human activities affect them. You'll take courses across earth science, geography, and environmental studies to understand environmental problems and solutions. The Co-op version requires you to complete paid work terms at environmental organizations or research facilities alongside your studies, giving you real workplace experience in the field.	You study how to design and build solutions to environmental problems using engineering tools and methods. This program combines traditional engineering disciplines like civil and mining with environmental science, so you learn both the technical skills and the ecological knowledge needed to tackle issues like water quality, land use, and resource extraction. It suits people who want to solve real-world environmental challenges through hands-on engineering work rather than pure science or policy analysis, and the built-in co-op terms let you test that fit in actual workplaces.	You study how Earth's climate and environment work, using chemistry, physics, and geography to understand weather systems, ecosystems, and human impacts. This program combines natural science with social geography, so you examine both the physical causes of environmental change and how people and communities respond to it. It suits students curious about climate science who want hands-on experience through co-op placements alongside their coursework.

Ranges are what each university publishes, not guaranteed cutoffs, and limited-enrolment programs often admit above them. Confirm anything you are about to act on with the university; each column links to its source.
