Why is ACORN telling me that my access is suspended?

If ACORN displays a message about your access being suspended, this is because of inappropriate use. Please contact your faculty or department registrar to request to have your access restored.

Students are expected to use ACORN responsibly, which means that you are not permitted to flood the system with requests or automate actions such as course enrolment.

What is ACORN?

ACORN is U of T’s student information system, and it stands for Accessible Campus Online Resource Network. Students use ACORN to enrol in courses, check fees and finances, update address and contact information and much more. The purpose of ACORN is to provide a more convenient, personalized and guided experience for students using U of T’s online services.

What is ACORN’s Peak Load Mode?

The ACORN dashboard with a yellow notice spanning the top of the page, and several areas that say that they are unavailable.
ACORN’s Peak Load Mode is a simplified version of ACORN that is used on peak enrolment days to reduce load on the system and improve performance. An example of a peak enrolment day is when priority course enrolment controls are removed for Arts and Science courses in August. The University will announce these dates ahead of time.

Note: When peak load mode is active, please do not refresh your browser while your course enrolment actions (e.g. enrol, switch section, drop) are in progress, or take the same enrolment actions in multiple browser tabs. Many students will be using ACORN at the same time, so enrolment actions will take longer than usual to complete, but are in progress even if the system is slow to respond. Refreshing your browser or repeatedly requesting the same action will only slow the system down further and increase the likelihood of your request being rejected entirely.

Why are some of ACORN’s services temporarily unavailable?

Due to the high volume of traffic during key enrolment days, the ACORN team has temporarily removed some ACORN features not essential to course and program enrolment to reduce the load on the system and its supporting infrastructure.

What features and information are unavailable during peak load periods?The areas that are unavailable in ACORN are shown.

  • Notifications
  • Today’s Timetable on your Dashboard
  • Your Invoice & Net Cost
  • Financial awards and aid information
  • Multiple degree invitations, if applicable

How was the name ACORN chosen?

The Office of Vice-Provost, Students ran a contest in early 2012 called “Name the New ROSI”. The winning entry submitted by a student in the Doctor of Dental Surgery (DDS) program was announced on April 18th, 2012. The name was selected because of its simplicity and the acronym ties to U of T’s logo oak imagery. ACORN stands for “Accessible Campus Online Resource Network”. The adjudication panel for the Name the New ROSI Contest met in early April and reviewed the nearly 1000 entries for the contest. Submissions were received from undergraduate and graduate students representing a range of programs from across the University’s three campuses.
