How do I delete a course that I am no longer using
While this functionality can be available to faculty, most institutions (mine included) restrict this functionality, and for very good reasons. You will most likely need to contact your Canvas Admin/support department and ask them to delete it. Depending on the course and your school policy, they may or may not help you.
If you do have this permission, then you can learn how at How do I permanently delete a course? However, I would advise extreme caution in using this feature if you have students in that course, and especially if the course includes student submissions of graded content.
I hope this is helpful,
