I had a colleague bring me this question this morning: "Can you make a course unavailable to students once the course has concluded (including "read-only" format - I don't want them to be able to see the course at all)?"
The short answer is NO, you cannot currently make your course unavailable without deleting it, which is not recommended. I checked with someone who knows a vast deal more about the inner workings of Canvas than I, and she says that while we currently do not have the capability of making a course unavailable, the company has said that it is working on an "un-publish" option.
I don't know when that will happen, but I will definitely keep you posted!
