Legally, the appointment is made by Governor in Council, but its statute requires as a condition before that that the House approve the appointment. But it doesn't happen legally until the order in council is made. That's part one of the indices of being in an executive-type position. But that's not to suggest the government is going to have inordinate or inappropriate control of the appointee. There's a difference between legal and parliamentary.
