In Canvas, deleted pages, files, and announcements can be recovered by typing "/undelete" after your course URL.
1. Click Home to navigate to the home page of your Canvas course.
2. Type /undelete to the end of the URL link and press enter.
3. A Restore Deleted Items page will appear, which will include a list of recent restorable items.
These will have brief descriptions that include what type they are, and the date of their creation and their last update. If an item is not on this list, it cannot be restored.
