How do I close a Discussion for comments in my course?
Canvas recently introduced a new page design called the New Canvas User Interface (UI). Depending on your Canvas view, your page design may vary from the images shown in this lesson. However, the functionality and location of the components remain the same.
To manually stop students from posting replies to discussion posts, use the close for comments link. You can also pin discussions to the closed for comments section on the discussion index page.
Note: You can automatically set your post to close for comments on a specific date by creating discussion availability dates.
