Course Selection Information - Winter 26

New for the 2025-2026 Academic Year

Course selection windows will open according to the windows outlined by the Office of Registrarial Services. Some changes have been made to course selection:

• All students can now register for both Fall 2025 and Winter 2026!
• Waitlists are available within WebAdvisor so students do not have to continually monitor for space availability. Please note the following:
  • You can join a waitlist if you meet the course requisites and restrictions.
  • You can see your spot on the waitlist to monitor any waitlist movement.
  • You can only place yourself on a waitlist for a course that you are not yet enroled in.
  • You can add yourself to the waitlist for only one section of the same course (even if the course is offered in multiple semesters!)
  • You can add waitlist on sections capped at zero (0) - these spaces may later become available depending on course demand.
  • You can add to yourself to waitlists that go above your maximum credit limit. If space opens for you to register, you would need to drop another course before registering into the approved waitlisted course.
  • If you register yourself in an open section of a course and you're already waitlisted on a different section of the same course, you'll be automatically removed from that waitlist.
  • If a space opens up in a section and you're the next person on the waitlist, you'll receive an email at your uoguelph account, and you'll have until 11:59 p.m. EDT the next day to register for the class yourself on WebAdvisor. If you fail to register within the timeframe provided, you'll be dropped from the waitlist, and the seat will be offered to the next student on the list.

WebAdvisor Waitlist Guide

    • Pre-reqs and co-reqs are noted within the course description on WebAdvisor

    • Check the restrictions on the course (on this website below and/or on the Registrar's Course Restrictions page)

Credit Overload Requests

To be considered for a Winter 2026 credit overload (students wishing to register for more than 2.75 credits) please complete the Credit Overload Request form by Thursday, January 8, 2026.  Credit overload requests will only be considered for approval by the B.Sc. Academic Counselling Centre beginning Thursday, December 18 2025,  pending space availability.

Restrictions

When a student wishes to take a course that they are not (currently) eligible to take, it is usually the course instructor who determines whether the student will be permitted to enrol. Campus-wide contacts for students to consult can be found on the Undergraduate Course Waiver Contacts page.

Many 1000-level courses were restricted to first-year students until Wednesday, July 23, 2025. A detailed list of these and other Priority Access course restrictions is posted on the Registrar's Office website. If restrictions are further lifted, the release dates will also be posted on that website.
