How do I delete a user from an account?
You can delete a user from your account. This process cannot be undone and will remove the user's data (including grades and ePortfolios) from all courses and groups.
Note: If your account manages user information through a student information system (SIS), changes will also have to be made in the SIS. Any changes made in Canvas will not be passed back to the SIS.
