B.Sc.(Env.) Majors

The B.Sc.(Env.) program offers the following majors:

  • Ecology
  • Environment and Resource Management
  • Environmental Economics and Policy
  • Environmental Sciences

The "calendar" referred to above is the Undergraduate Calendar. More information about the degree course requirements may be found in the "Degree Program" section of the respective calendars.

Choosing your Major

To help you decide which major works best for you, you can talk to Faculty Advisors and your Program Counsellor.

News and updates about choosing your major and meeting the Faculty Advisors will be posted on the B.Sc.(Env.) Program Counselling home page and emailed to the enviro listserv. It is your responsibility to talk to the appropriate Faculty Advisors to collect information on the majors in which you are interested. The Undergraduate Calendar provides the Schedule of Studies (required courses) for each major.

A handout is distributed to students attending the Choose Your Major Event for the B.Sc.(Env.) Program, which provides information on how to contact Faculty Advisors to help inform your decision, and complete the required paperwork for declaring your major with your Program Counsellor.

Declaring or Changing Majors within the B.Sc.(Env.)

All B.Sc.(Env.) first year students are admitted as "undeclared". You must declare your major by the end of Semester 3; for co-op students this deadline is end of Semester 2.

You will need to obtain an Undergraduate Schedule of Studies Change Request Form in order to declare or change your major. The form is available from the Program Counselling Office or online. Your Program Counsellor will need to sign the form. Make an appointment with your Program Counsellor to discuss your choice and obtain her signature. The final step is to submit the signed form to Enrolment Services in the Office of Registrarial Services located on the third floor of the University Centre. Once you have submitted the form to Enrolment Services, check My Progress on the Student Planning system through WebAdvisor to ensure it is correct. Processing of your form may take several business days.

It is recommended that you consult with your Faculty Advisor for a better understanding of program and course information as well as when choosing restricted electives. The Undergraduate Calendar provides details regarding specific degree requirements.

Students who would like to transfer into a major that is not in the B.Sc.(Env.) program must apply to transfer through the Admissions Office in the Office of Registrarial Services. Transfer information can be found on the Admissions webpage. It is recommended you speak with the Program Counsellor of the program you wish to transfer into for academic advice.

Students who would like to transfer into the B.Sc.(Env.) from another University of Guelph degree must apply to transfer. Transfer information can be found on the Admissions webpage. Please contact the B.Sc.(Env.) Program Counsellor if you have questions.

Other Changes Requiring Program Counsellor Approval

If you are interested in the curriculum offered through a more recent calendar year than your admission to the B.Sc.(Env.) program, please consult your Program Counsellor. You will need approval from your Program Counsellor if you are using a Calendar Year other than the one assigned to you in your first year in the B.Sc.(Env.) program.


As of 2022-2023, if you are interested in a secondary area of focus, you have the option of declaring a minor. Minors are not mandatory for the B.Sc.(Env.) degree so the required credits are separate from the requirements and restricted electives for the B.Sc.(Env.) majors. Degree completion with a minor may require more than four years (five years for those in co-op).

Note that a maximum of 2.50 credits may be used for both minor and major requirements. For example, if you need GEOG*1300 for your minor, it will be double-counted with your major (i.e. it will count as a requirement for your major, as well as your minor).

To declare a minor, follow the same processes as listed above, indicating ‘Minor' rather than ‘Major' under "Specialization Type" on the Undergraduate Schedule of Studies Change Request Form. Consult with your Program Counsellor for more information.

See this List of Minors for the current calendar year. You may need to discuss the calendar year for minors with your Program Counsellor.
