To all ROSI / ROSI Express / Degree Explorer Users:

This year, fall/winter course enrolment will run from June 24 to August 6, 2025, with our heaviest enrolment day happening on July 25. View the full schedule on the SIS SharePoint site.

If students contact you about slower than usual processing times during enrolment, please inform them that this is due to high system traffic. Advise them to only use one device to access ACORN and to avoid refreshing unnecessarily, as this can increase the load on the system. During heavier enrolment days, access to non-enrolment functions may be temporarily restricted to help manage system performance.

To check for ongoing system updates, students can visit the ITS System Status website and course-related questions should be directed to their registrar.

We will be working directly with divisions that have active course enrolment to monitor the system and to communicate any issues.

We also ask staff to limit use of ROSI-related processes that may place additional burden on the system during enrolment days. Please view the critical dates calendar.

Thank you for your support during this year’s fall/winter enrolment.

Sincerely,
Student Information Systems
