Seen the Govenor General and her husband in 2D&F and some minders in military uniform in 3DEF.
I was in 1 and was asked to stay seated on arrival until they had left. Though that didn't work as intended as there was a car waiting at the jetway steps (staff ones on the jet way not the rear stairs one) and no one there to open it, so they were waiting there while everyone else just walked along the jet bridge.
We were also late leaving as they waited to after everyone else had boarded. Like after the ground staff had walked down with the printed out list and after scheduled departure time.
