In my experience, Canvas definitely puts the due dates of UNPUBLISHED assignments on the student's calendar. I cannot tell you how frustrating it is, and I have not seen a solution yet. Often when I copy the spring semester class to the fall semester, Canvas adjusts the due dates, and I tweak the assignments--leaving some unpublished because I don't want to use them that particular semester (but may use them in the future). Invariably I will get emails from students about these unpublished assignments because they want to know how to complete them. They cannot see them (they're unpublished) but their Canvas Calendar is telling them that the assignment is due. From my experience, Canvas puts the due dates of published and unpublished assignments on the student's calendar. I don't know how to fix that.
