Why study Environmental Science?

Tackle some of the most important issues we face today: climate change, natural resource management and sustainability. Examine the endangerment of species, natural systems and the effect of pollution. As an Environmental Science student, you’ll follow a path where geography, geology, biology, chemistry, computer science and engineering intersect.

Through labs, lectures and projects, you’ll learn to assess the impact of human activity on natural cycles and landforms. You can choose to apply your skills during an internship or field research. You’ll also:

  • Study the causes and consequences of environmental change
  • Learn to gather and interpret statistical data
  • Acquire technical knowledge of computerized mapping and Geographic Information Systems (GIS)
  • Learn to develop effective and efficient policies for environmental management
  • Choose to specialize in Ecology, Hydrosphere or Geoscience

After graduation, your knowledge and technical skills will prepare you for a career in research.

Program highlights

  • Science First-Year Experience Program - For students from other Canadian provinces. Connect with other first-year science students and engage in interdisciplinary, research-based approaches to the foundational sciences.

Program structure

A Bachelor of Science degree takes a minimum of three or four years (90 – 120 credits) of full-time study, depending on your academic background.

Program options

  • Honours in Environmental Science (69 credits)
  • Specialization in Environmental Science (69 credits)

Academic streams

Once students are admitted, they may choose from one of three academic study streams:

Honours programs: Students applying directly to an honours program should list it as their first choice. If not admitted to honours, they will automatically be considered for the next highest program (i.e. specialization or major).

Minimum cut-off averages should be used as indicators. The cut-off data may change depending on the applicant pool. Applicants who meet the stated minimum requirements are not guaranteed admission to these programs.

After your degree

There is a growing demand for geographers and environmental scientists. Many employers require researchers to conduct environmental assessments for major projects, or seek technical specialists in computer-assisted cartography and GIS. Environmental Science alumni have established careers in a range of fields including:

  • Environmental impact assessment
  • Resource conservation
  • Environmental consultant
  • Geographic Information Systems analyst
  • Water scientist

Recent graduates have become researchers with the NAFTA Commission for Environmental Co-operation and the Secretariat for the UN Convention on Biodiversity.
