What it is	This program teaches you how to design and manage the built and natural environments — from city neighborhoods and transportation systems to parks and land use. The co-op requirement means you'll alternate between classroom semesters and paid work terms at planning firms, municipalities, or environmental organizations, giving you real experience while you study. It suits people who want hands-on learning, enjoy solving problems about how communities develop, and are willing to commit to the co-op schedule.	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 the natural systems that support life on Earth — combining biology, chemistry, geology, and geography to understand ecosystems, environmental problems, and how living things interact with their physical surroundings. This pathway is structured to integrate multiple science disciplines rather than focus narrowly on one, and it includes mandatory co-operative work terms where you apply classroom learning to real environmental jobs. It suits students curious about how nature works across scales, from molecules to landscapes, who want hands-on experience before deciding on a specific environmental career.

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.
