Courses are automatically added to Canvas the semester before they are to occur.
If you do not see your course in Canvas, it may be hidden from the dashboard. Go to the "Courses" menu in Canvas and click "All Course" to find the course. Click the star next to the course for it to appear on the Dashboard.
If the course does not appear on the list of All Courses, check AccessAU to make sure you are listed as the instructor of record and work with the registrar's office to be added.
