Biological Science – Environmental Toxicology specialization

Return to {$returnto_text} Return to: Programs (by degree)

General information

Environmental Toxicology is an interdisciplinary applied field, which focuses on the effects of contaminants on the environment and involves agriculture, health, industry, and urban development. This specialization within the Biological Science program  combines a strong base in biology and chemistry, with a focus on physiology, biochemistry, environmental science, and environmental chemistry.

In addition to the regular program, a co-op program is also available. Students in Environmental Toxicology interested in the co-op program , should contact the Faculty of Science Co-op Coordinator as early as the fall of their second year.

Admission requirements

Admission is competitive. The specific average or standing required for admission varies from year to year. Students are selected by taking into consideration a wide range of criteria including school marks, distribution of subjects taken, and performance in subjects relevant to the academic program. Possession of the minimum requirements does not guarantee acceptance. Preference will be given to applicants with the best qualifications.

Current Ontario secondary school students must complete the Ontario Secondary School Diploma (OSSD) with six 4U or 4M credits including English (ENG4U), Advanced Functions (MHF4U), and two of Biology (SBI4U), Calculus and Vectors (MCV4U), Chemistry (SCH4U), or Physics (SPH4U). In addition, a combined minimum 70 per cent average in math and science courses is required. It is recommended that all four MCV4U, SBI4U, SCH4U and SPH4U be taken. All other applicants should refer to admissions  for the requirements for their specific category of admission.

Program details and degree requirements

Although reasonable efforts will be made to adhere to the following program map, course requirements and term offerings may change.

Year 1

Semester 2 (15 credit hours)

Year 2

Year 3

Year 4


No more than 42 credit hours may be taken at the first-year level.

*Electives and breadth requirements

All students must complete 27 elective credit hours including at least one senior biology elective. Students not accepted to take BIOL 4410U  and BIOL 4420U  must take an additional two senior biology electives for a total of 33 elective credit hours. A senior biology elective is defined as any 4000-level biology course not specified in the course map. At least 15 elective credit hours must be in courses offered by the Faculty of Science including the 3 credit hours in a senior biology elective; the additional two senior biology electives required for students who are not enrolled in thesis cannot be used to meet this requirement. In order to satisfy breadth requirements, no more than 9 elective credit hours may be in biology (BIOL) courses; at least 12 elective credit hours must be in courses outside the Faculty of Science.

**Thesis Project or Senior Biology electives

Students in clear academic standing who have completed 90 credit hours of their BIOL program and six third-year required courses may optionally apply to take a two-course sequence consisting of BIOL 4410U – Biology Thesis Project I and BIOL 4420U – Biology Thesis Project II. Students not accepted to take the thesis courses must complete two additional senior biology electives instead. A senior biology elective is defined as any 4000-level biology course not specified in the course map. A student meeting the above requirements who does not take BIOL 4410U and BIOL 4420U may optionally apply to take BIOL 4430U – Directed Studies in Biology as one of the required senior biology electives. Opportunities for the Thesis Project and Directed Studies options are limited; for either of these options, students must apply through Science Advising by March 30 following completion of the first three years of the program.
