Q. Can I add a TA to a canvas course?

No, but TLC can.

If you provide TLC with the name and e-mail address of the individual we can add them as a TA to the course. If the individual is affiliated with HLS this can be done right away. If the individual is not affiliated with HLS then we need to have permission from the Registrar's Office to add them, in this case they will not added right away.
