What it is	Environmental sciences combines biology, chemistry, economics, and Earth systems to understand how environments work and how human activity affects them. The co-op option lets you alternate between study terms and paid work placements with environmental organizations, government agencies, or companies, giving you real experience alongside your degree. This program suits people who want practical skills in environmental problem-solving and prefer learning through both classroom study and workplace application.	Water Science combines biology, chemistry, physics, and geography to study how water systems work and how to protect them. You'll examine lakes, rivers, and groundwater from ecological and physical angles rather than focusing only on engineering solutions. This program suits students interested in environmental problems who want a science-based approach grounded in both living systems and earth processes.	An Honours Science degree lets you study a science subject deeply — biology, chemistry, physics, computer science, or another physical science — and choose your own focus within it. Unlike a general science program, an Honours degree requires a concentrated major and typically includes a research or capstone component. The co-op option means you alternate between school terms and paid work placements in science-related jobs, which suits people who want real workplace experience alongside their degree.

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.
