Before you answer those questions, I want to draw the committee's attention to chapter 20 of Marleau and Montpetit, page 864, that “...public servants have been excused from commenting on the policy decisions made by the government.”
So you don't have to answer anything you feel might compromise your ability to do your job in the ministry. Pick out what questions you want from Mr. Easter's list, and I'll add on 30 seconds.
