Is there anywhere to go to look at the history of a course? Like who has been in the course, when they were last there, who all had access to the course, and thing like that?
There is a permission to allow viewing course analytics. This button will be visible from the front page of the course, in the right sidebar. If you don't see the button, you will need to talk to your school's canvas admin to either gather the info or to give you the permission.
It tracks all users that are part of the course, including page hits, submissions, scores, etc. It doesn't seem to track admins that can see courses without actually being registered as part of the course.
You can also see on the people page when the last time someone viewed your course. That should be visible to anyone in the Teacher role, if I remember right.
