There are a number of elements to your question. First of all, we'll take the salary of the staff. Those are public servants and their salaries are set by the Treasury Board based on their academic standards, qualifications, how they publish papers, and so on, like other academic positions in the public service. So I don't have specific control over their salary, and it's not based on their student ratio.
