How do I add a colleague to a course that I was already taught? When I go into People - there is no longer and add button available to do that.
This means that you need to change the section and course end dates in order to add someone to the course. If you cannot change the date yourself, you will need to contact your Canvas Administrator and ask them to change the end dates for you. At our institution, we do not allow changes to be made to a course after the semester is over including adding someone into the course. We have instructors request development courses, copying past courses into them and then adding instructors into the development course.
I echo exactly what Robbie says, except to add that if you have the Copy Course button available from settings, it's a quicker process than creating a Dev course and importing content. We also do this at my school rather than adding people to existing courses so that the new person does not see any student data. Depending on how your Registrar interprets FERPA guidelines it's possible not cool to add someone to a course with teacher access if there is student data present.
