Comparative Physiology

About the Program

Physiology is the study of living matter and its interaction between internal and external environments. It integrates physical and life sciences in order to understand body functions and the origins of disease in both plants and animals.


Honours Bachelor of Science

Program Options


After completing your first year, you'll be asked to confirm what program(s) you wish to study – your Programs of Study. They can be integrated in unique ways to obtain your U of T degree, but must be one of the following three combinations: one Specialist; or two Majors; or one Major and two Minors. You don't need to worry about that now, but if you'd like to learn more about this process, watch our handy video (7 min).

Admission Requirements

You apply to an admission category, which is a collection of similar programs. Once you've accepted an offer of admission to our campus, we go into greater detail about specific program and course selection options.

At the end of your first year, you will choose your program(s), which means that your first year is an excellent opportunity to explore the full breadth of offerings.

Regardless of what you study, remember that you will receive a prestigious University of Toronto degree when you graduate that tells everyone that you are ranked among the best in the world!

A new innovation in remote learning has taken root in a biology course at the University of Toronto Mississauga: bringing the lab to students. Biology professor Ingo Ensminger teaches Plant Physiology, a third-year course focusing on how plants are formed and function in their environments.

A group of U of T Mississauga students are ditching their lab coats in favour of gym clothes. The students are hitting the gym and getting their hearts pumping for a fourth-year physiology course created and taught by biology professor Bryan Stewart, which relies on a first-time partnership with the Recreation, Athletics and Wellness Centre (RAWC).

Meltdown: A Climate Change Summit

“Our house is on fire,” said Dianne Saxe, PhD, Ontario’s former commissioner of the environment, speaking to a packed lecture hall at UTM during the Sept. 24 event, Meltdown: A Climate Change Summit. “We need to reduce our use of fossil fuels.”

Tip Sheets

The Career Centre offers dozens of tip sheets with helpful information about topics related to searching for work, planning your career, and pursuing further education.

View to the U: An eye on UTM research

View to the U is a podcast that features U of T Mississauga faculty members from a range of disciplines who will illuminate some of the inner-workings of the science labs and enlighten the social sciences and humanities hubs at UTM.

Peter Kotanen

On this latest episode of VIEW to the U, Professor Peter Kotanen from the Department of Biology at UofT Mississauga discusses his research and current projects, which have “ecological interactions between plants and their natural enemies,” such as herbivores, insects, and pathogens, at their core.

Other Programs to Consider

Biology for Health Sciences

Biology for Health Sciences

This program focuses on areas of biological science that relate to the health of humans and will provide a strong foundation for students interested in pursuing a career in the health sciences

Ecology & Evolution

Ecology & Evolution

Ecology and evolution are sister disciplines, both encompassing the study of natural selection, life history, development, adaptation, population, and inheritance. Ecology and evolution are broad disciplines seeking to understand the origins, diversity, and distribution of organisms.
