Thank you, Mr. Chair, and let me through you thank the witnesses for appearing today.
I suspect very strongly that most of my questions are going to need to be answered by Ms. McKeen.
I'm sorry to keep on this, but there are a few questions I'd like answered.
First, can you explain and give us some examples of situations in which an officer would direct a transporter not to carry a traveller to Canada—in other words, the negative side of this?
