Frequently Asked Questions

“Reserve Capacity Criteria”

  • Although a course may appear to have seats available, the seats in the allotted “reserve capacity” that you have access to may be full at this time.
  • Oftentimes, faculties release a specific number of seats to students outside of their faculty. Once faculties are certain that there are enough seats for their students, these seats will be released.
  • We encourage you to try enrolling in a different section (if available) or a different elective with space and continue to try to swap into your preferred elective on Mosaic once the reserved seats are released.
  • To confirm the reserved seat release date, you must reach out to the home faculty of the course offered.

“Pre-requisites Not Met”

  • Please refer to the course website (Course Descriptions and Outlines – MBA Program ( to view the prerequisites.
  • If you do meet the prerequisite, reach out to us at so we can investigate this for you further. Please include your full name and student number in your inquiry.

“Department Consent Required”

  • This error message means this course is currently full.
  • Course enrollment will be monitored carefully.  Please try back often to see if a seat has become available.
  • In the meantime, we also suggest you register in an alternate course.

Note: You may get the “Department Consent Required” message even when the course does not appear to be full. This means someone has dropped the course and a seat is being given to the next student on the wait list.

  • There are no available seats left for enrollment.
  • You can continue to monitor Mosaic for an opening in your desired course until the end of the add/drop period each term (see Dates and Deadlines).
  • We recommend that you log into Mosaic to search for other potential courses that could fit your needs.
