What it is	You study how to design and restore buildings while minimizing environmental impact, combining architecture, history, and ecological design. This program emphasizes conservation of existing structures and sustainable materials and methods, setting it apart from general architecture programs that focus mainly on new construction. It suits students interested in heritage preservation and green building who want hands-on experience through co-op placements.	You study how to run and launch businesses while learning environmental science and sustainability principles. This combines business skills with ecological knowledge, so you understand both profit and environmental impact. The co-op requirement means you alternate between classroom and paid work terms, giving you real workplace experience in green business and sustainability roles. It suits people who want to work in business but care about environmental problems.	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.
