Good morning, @bgcormier5 ...
Adding students may or may not be something that you, as an instructor, can do yourself...depending on if your school already has processes in place to automatically enroll students from your school's SIS (Student Information System) into Canvas. This Guide, How do I add users to a course?, should be of help to you.
Sing out if you have any other questions about this. Stay safe...be well.
