What it is	You study how to repair, restore, and upgrade old buildings while making them environmentally sustainable. This program combines architecture, engineering, and environmental science — it's more specialized than a general architecture or engineering degree because it focuses specifically on conserving heritage structures and reducing their environmental impact. It suits people who care about preserving historic buildings and solving practical problems with green technology.	You study how Earth's physical systems — rocks, soil, water, and climate — interact with living things and human activity. This program combines geology, geography, and environmental science rather than focusing on just one. The co-op option lets you do paid work terms with employers in the environmental or resource sector alongside your coursework, giving you real experience before you graduate. This suits people interested in understanding environmental problems and possibly working in conservation, resource management, or environmental consulting.	You study physical sciences — chemistry, physics, geology, and environmental topics — with a focus on how they connect to human health and the living world. This stream emphasizes the intersection between earth and life sciences rather than pure physics or chemistry alone. The co-op option lets you do paid work terms at relevant employers alongside your degree. It suits students interested in environmental health, toxicology, or science careers that bridge the natural world and wellness.

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.
