LORIS Error Messages

This link error means that there is either a tutorial or a lab linked together with the lecture that you have not selected. To correct this situation, select the lecture and the tutorial or lab from the list when performing the class search. Lectures carry the credit weight; labs and tutorials carry 0.0 weight.

This link error means that you have selected either a lecture or a tutorial/lab at the same time as a course in which you are already registered. Either select the lecture at a different time, choose another course or drop the course causing the conflict.

This error means that the course has seats reserved for specific reasons determined by the department. If there are seats remaining, contact the department about your eligibility.

This error means that you are attempting to register in a course that has a prerequisite. For example, before you can register in a first-year calculus course, you must write the online Calculus Preparation Evaluation (CPE). Similarly, some language courses may have a high school course as a prerequisite.

You are attempting to register in a course that has already reached its capacity. On the LORIS screen, a “C” will show beside the course. Choose another course or keep checking LORIS, because students make changes during the summer and a space may open up. When searching for this course, you can see how many spots are available. Make your interest in the course known to the department. If a department has authorized wait listing to be used and the course is full, you will be prompted to add yourself to the wait list. Refer to the "wait list" term for instructions.

This link error message means you are attempting to register in a course that is restricted due to year level.

This link error means that you have already selected this course and perhaps have dropped it. If now you want to take this course go to the Add/Drop Classes screen, from the drop down menu beside the course, click on “Re-Enrol.” Then click on “Submit Changes” at the bottom of the screen.

Year 1 students are limited to a maximum of 2.5 credits in a term, senior students are limited to 3.0 credits, and students on academic probation are limited to 2.0 credits. LORIS will not allow you to register in more. Contact your Academic Advisor for assistance.

This error means that multiple sessions of registration are open for your student number. Please log out of all LORIS sessions on any open browsers and/or devices and try again. A full restart of your computer or mobile device may be required. If the error persists, it may be that administrative staff are currently reviewing your record. Please wait and try again later.

Some programs have restrictions on certain courses or course sections in order to reserve space for students who are majoring in that particular program. These restrictions may be removed on a specific date, or may remain indefinitely. To see if the restriction will be removed, search the course in Browse Classes.

For more information, please refer to How to Waitlist.
