You can see comments from your instructor in the Grades page. Most comments are located in the assignment sidebar. However, your instructor may also leave comments in your assignment submission as annotations.
In Course Navigation, click the Grades link.
Locate the assignment and click the comment icon [1]. View the comments in the assignment [2]. You can also view the author, date, and time of the comment.
Additional information about viewing comments in the assignment's rubric or annotations can be found in the following Canvas Guide: How do I view assignment comments from my instructor?
