I would actually not recommend re-using the same course shell for another round of your course with new students. Rather, what many schools do is to create a brand new course shell, add the new students to that new shell, and then import (copy) the content from the past course into the new course. This way, you can keep all students in your past course without needing to remove them. If a student in that past course ever challenged you on a grade or needed to access something from in the course, you'd have to re-enroll the student temporarily so that he/she could access the course.
I'm not sure if you are using a paid Canvas environment or if you are using the FFT (Free For Teacher) version of Canvas. If you are using a paid Canvas environment (your Canvas URL would look similar to https://SchoolName.instructure.com where SchoolName is the name of your school), you should talk to your Canvas administrator or someone from your school's Online Learning / eLearning / Distance Education team about what the proper procedure is for getting a new course shell. They probably have a process already in place. If you are using the FFT version of Canvas, you should be able to create a new course shell and then import content into the new shell from the past course.
How do I copy content from another Canvas course using the Course Import tool?
I hope this will be of some help to you. Please let Community members know if you have any other questions about this...thanks!
