About the Program

This program offers teachings in biology, the study of living organisms and involves observation and analysis of the tree of life. The foundation of biology is based upon the core concepts of evolution: natural selection and speciation.


Honours Bachelor of Science

Program Options

Specialist, Major, Minor

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!

Discover Your Potential

Vanessa Parise

Vanessa Parise’s journey as a U of T Mississauga student is defined not by the hurdles that tripped her up, but by how she brilliantly picked herself back up to maximize her post-secondary experience.

Eugenia Addy

As a UTM science student, Eugenia Addy (formerly Eugenia Duodu) became a volunteer with the Visions of Science Network for Learning, encouraging low-income and underprivileged children to pursue science, technology, engineering and math (STEM). Today, at 32, Addy (PhD ’15) is Vision of Science’s CEO.

Marc Johnson

Biologist Marc Johnson knows the value of an early introduction to science. His own childhood featured stacks of Little Golden Book nature guides and free-range access to the Presqu’ile Park nature centre near his grandmother’s cottage on the northern shores of Lake Ontario.

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

Molecular Biology

Molecular Biology

Molecular Biology is an interdisciplinary science that draws its major themes from biochemistry, cell biology, and genetics. Its emphasis is on the structure, chemistry, and functions of nucleic acids and focuses on the biochemical basis of cellular genetics.
