in toronto they now have the machines determine who gets the lucky number. it is a very prompt service.
that being said, i was way ahead of my friend escaping their eagle eyes.. and as i passed thru the last double doors i was questioned extensively. the agent was disappointed i had a new passport and could not trace my last steps.
10 mins later and over 100 people went thru despite some voluntarily stopping to be searched, most from an international flight, and my friend was the next person to be questioned after me. she got the same battery of tests. her customs card was marked differently than mine... so somehow, they still know.
ps we had absolutely nothing to declare tho we both put a nominal amt in case they find some sand they want to charge me gst on. lololol
