BSc (120 credit hour) Major in Environmental Science

The 120 credit hour Major is suited to students who want to focus on Environmental Science, but wish to have a program that is somewhat less constrained than the Honours program. Environmental Science Majors complete 36 credit hours in Environmental Science courses. Research and other experiential learning opportunities are available through laboratories, field, special topics and internship courses.

A Co-op option is available for students enrolled in a 120 credit hour BSc Major program in Environmental Science. See Co-operative Education Program.

Program requirements

In addition to fulfilling the requirements outlined in the Academic Regulations and College of Arts and Science Degree Requirements, students in a BSc Major program in Environmental Science must complete the 1000 level courses (listed below) and the Common Core courses - Majors (also listed below).

1000 Level Courses (to be taken in first year, if possible)


  • BIOL 1010.03: Principles of Biology Part I or BIOL 1020.03: Introductory Biology I: Cells, Genetics and Evolution
  • MATH 1000.03: Differential and Integral Calculus I or MATH 1215.03: Life Sciences Calculus
  • STAT 1060.03: Introductory Statistics for Science and Health Sciences
  • CHEM 1011.03: Concepts in Chemistry: Structure and Reactivity
  • CHEM 1012.03: Concepts in Chemistry: Energy and Equilibrium
  • ERTH 1080.03: Geology I

  • ENVS 1200.03: Current Environmental Challenges: Analysis and Solutions (grade of B- or higher)

Students are encouraged to take three credit hours of their Language and Humanities requirement in their first year.

Also required but usually taken in the second year:

  • ECON 1101.03: Principles of Microeconomics or ECON 1102.03: Principles of Macroeconomics*
Common Core Courses - Majors

To be completed over the course of a four year degree program: Common Core Courses introduce students to the scope and magnitude of Environmental Science and are designed to provide students with an appreciation of the scientific, historic, legal and social aspects of environmental issues.

  • STAT 2080.03: Statistical Methods of Data Analysis and Inference*
  • BIOL 2060.03: Introductory Ecology
  • PHIL 2480.03: Environmental Ethics**
  • ENVS 2310.03: Energy and the Environment
