How do I delete a Discussion 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.
You can delete a Discussion topic at any time.
