@kevinw , I just checked and if students clicks on the assignment it shows their grade and comments/feedback in the upper right corner. So it seems like nothing special other than the URL to the assignment. Yet, linking to content within Canvas doesn't work that well because the Canvas page you're linking to has the sidebars. This means that if you redirect to that page you're going to end up with duplicate side-bars. The normal sidebars on the page and the sidebars on the page you're linking to.
