Future Students


Students can apply to the Toxicology program directly from secondary school or they can transfer from another program as an in-course student usually by the end of semester 3. For more information, contact the Director of the Toxicology program.


Admission Requirements

Course requirements to gain admission to the toxicology program include:
  • English (12 U)
  • Advanced Functions (12 U)
  • Two credits (12 U) from Biology, Chemistry, Physics
  • Two additional credits (12 U or M)

Biology, Chemistry, and Physics are strongly recommended for B.Sc. majors.

For more information, please visit the Undergraduate Calendar.


Co-operative Education

The Toxicology Co-operative Education Program gives students the opportunity to gain valuable hands-on experience that will complement their academics.  Positions in industry and government allow them to gain related skills in the experimental and regulatory aspects of toxicology. To participate, students can select the Co-op program at the time of application to the university, or alternatively students in the regular (non-Co-op) program may apply by December 1 of their first semester to transfer into Co-op. All co-op students must achieve a 70 per cent overall average which must be maintained throughout the student's academic program. Toxicology Co-op students complete three work terms after their third academic semester.

Sample work term placements for our Co-op students include:

  • Agriculture and Agri-Food Canada
  • Apotex Inc.
  • Campbell Company of Canada
  • Canadian Food Inspection Agency
  • Environment Canada
  • Health Canada
  • Kraft Canada
  • Mandel Scientific Company Inc.
  • Maple Leaf Consumer Foods
  • Public Health Agency of Canada

Toxicology Program

In the Toxicology Program at Guelph, students will:

• take eight core toxicology courses that provide a strong foundation in both biomedical and environmental toxicology where they will be concerned with issues such as the risk of cancer from exposure to environmental agents, including both natural and synthetic chemicals;

• study the metabolism of carcinogenic and other toxic substances, and the effects of these
substances on DNA;

learn about epidemiology (the distribution of toxic effects on large populations of organisms), and how toxic substances act at the molecular level (biochemical toxicology) as well as their effects on the whole animal (toxicological pathology);

• assess the effects of both natural and synthetic chemicals and their movement, distribution and breakdown in the environment;

• examine the structure and function of natural biological systems and learn how to use laboratory experiments to predict effects in the field;

• understand the metabolism and breakdown of toxic substances - especially the rates at which the processes occur in which many toxicants enter the environment in industrial effluents or through insecticides and herbicides;

• learn how to calculate the dose received by target and non-target organisms and how to determine safety factors, using the best available information to assess safe and efficient doses.
