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.	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.	This program trains you to teach science — biology, chemistry, or computer science — at the middle and intermediate school levels in French-language schools. You earn your Bachelor of Science and teaching qualification simultaneously by combining science courses with education coursework, rather than studying science first and then adding teacher training afterward. It suits students who are fluent in French, strong in science, and committed to teaching younger students.
