Summer 2026 Course Selection

Course selection for Summer 2026 begins on Tuesday, March 3rd, 2026 and will open in windows based on certain criteria. Course Selection Windows are posted on the Office of Registrarial Services' webpage. 

Once your window opens, you will be able to add courses until May 11th, 2026 for 6-week courses, or May 15, 2026 for 12-week courses. However, we encourage you to add when your window opens as some courses fill up quickly. 

If you have any questions about your program and/or the courses you should be taking, please email oac.pco@uoguelph to connect with your Academic Advisor.
