It depends who you get...again I have gone through Toronto airport at least 50 times in the past 2 years with AP. The very first time you use it each year you go into the back (secondary), they give you priority and stamp AP, plus give you I-94 and stamp passport. Sometimes, the guy can be a dick and ask lots of questions. Othertimes, it's hello and goodbye. Bring job stuff, etc for the first time. Also, all conversation is taped and videoed, so don't lie or mess around!!
The very interesting thing about Toronto is that each time you use it after the first time, the initial officer just writes in pen "reparolled Oct 1/03" and you are on your way very quickly. In Miami, or other aiports in the U.S., I always have to go to secondary for a brand new I-94 card and stamp in passport and on AP, which is time consuming and a pain in the as*!!
The Toronto system is MUCH quicker!!
