Course Enrolment

Course enrolment is the process of adding the courses you plan to take over the next academic term(s) in ACORN. Before you enrol in courses, it is a good idea to spend some time to plan your courses, create a weekly schedule and understand the enrolment controls. You should also make sure you know how to use ACORN.

The following academic resources will help you map out your year. You can find information about programs and courses, see when courses are held, create a mock timetable and learn about any prerequisities that you may need.

Step 1: Find your Course Enrolment Period

Course enrolment takes place during different enrolment periods in ACORN. These enrolment periods apply to undergraduate students in the Faculty of Arts & Science and undergraduate students in the John H. Daniels Faculty of Architecture, Landscape, and Design.

Priority Enrolment Period

During this period, certain groups of students are given priority for enrolment into certain courses. In addition, the maximum course and term load is different in the priority enrolment period.

Non-Enrolment Days

All of the above enrolment periods are separated by non-enrolment days when course enrolment will be closed for Faculty of Arts & Science courses. The non-enrolment days for the Fall and Winter sessions are:

  • August 1, 2019
  • August 6, 2019
  • August 8, 2019


Step 2: View your Start Time

Your start time indicates the earliest date and time at which you can start enrolling in your courses. Since course enrolment starts on different days for different students, make sure that you know when you can start enrolling in courses. To find your start time, check the enrolment periods above.

On your start date, you will not be able to log into ACORN until your start time. For example, if your start time is 3:45 p.m. then that's the earliest time you can access ACORN on that day. The next day, however, you will be able to log in at any time during ACORN's hours of operation.

Start times are based on a student's year of study. For the Fall and Winter session, your year of study is determined by the total number of credits you have completed and will be completing during the preceding Summer session. For the Summer session, your year of study is based on the number of credits you have completed and will be completing during the preceding Winter term.


Step 3: Enrol in Courses

Now that you have planned out your courses, checked your start time and know how to use ACORN, you are ready to enrol in your courses.You can log into ACORN and save courses in your Enrolment Cart at any point before your first day of course enrolment. By saving courses in your enrolment cart, you are not automatically enrolled in those courses. You will have to enrol in each course individually. If a course is full, you can add yourself to the waitlist for that course.

At your course enrolment start time, you can start enrolling in the courses you have chosen. Log into ACORN and begin enrolling in courses using Search or the Enrolment Cart. You can continue to enrol in courses until the deadline to add or make changes to courses as long as there is space in the course and you meet the enrolment controls.

Remember that course enrolment is done in real time, on a first-come, first-served basis. Courses fill up fast, so prioritize your top courses and enrol in those first.


The waitlist is a feature that lets you "line up" for a course that's currently full, in case a space becomes available in the future. If a student cancels the course and you're next on the waitlist, you'll be enrolled automatically. An email will be sent to your U of T email account to notify you of the enrolment. If you get enrolled, be sure to add any practical or tutorial sections associated with the course.

Important to note:

  • In the Fall and Winter Session, you can be on the waitlist for up to 2.0 FCEs per term
  • In the Summer Session, you can be on the waitlist for up to 2.0 FCEs 
  • Being on a waitlist does not guarantee that you will be enrolled in a course
  • Waitlisted courses are counted in your maximum course and term load
  • Not all courses have waitlists. See the waitlist column in the Timetable.
  • Waitlists are available for lecture (LEC/L) sections only
  • See the Academic Dates to find out when waitlists will close

Cancelling courses

If you decide that you no longer want to take a course, cancel it as soon as possible. This applies to courses that you've added to the waitlist, as well as those in which you are enrolled. If you cancel the course before the deadline to add courses, your space becomes available to another student.

If the course's enrolment is managed by the academic unit, you will not be able to cancel the course on ACORN. Please contact the academic unit or your College Registrar's Office to cancel the course.

It is important to note that refund deadlines are not the same as course cancellation deadlines. Check Student Accounts for the refund schedule.


Step 4: Pay your Fees

After you enrol in courses on ACORN, the final step to complete your registration is to pay your fees. If you do not pay or defer your fees by the fees/deferral deadline, you may be removed from your courses.
