Environmental Sciences (Regular/Co-op)
80–83%OUAC WSECo-op available
Prerequisites
- English (ENG4U – min. 70%)
- Advanced Functions (min. 70%)
- Calculus and Vectors (min.70%)
- Any two of the following: Biology, Chemistry, Earth and Space Science, Mathematics of Data Management, or Physics
What to watch for
This one is in the Faculty of SCIENCE, not the Faculty of Environment, and that matters: it requires English, Advanced Functions and Calculus and Vectors (all 70%) plus two sciences, admission average low 80s. Specializations (Ecology, Geoscience, Water Science) are chosen after first year, and the Geoscience path lines up with registration as a Professional Geoscientist of Ontario. If you want environment without the calculus and with a policy/society focus, the Faculty of Environment runs separate admission programs — Climate and Environmental Change, and Environment, Resources and Sustainability.
