"Easy process, at least it is if you already have US Global Entry. I was in and out in 15 minutes. They don't tell you where to find the office in Pearson though. It's on the Departure Level, in Terminal 1, between numbered check-in stations 8 and 9 - closer to 8. Look for \"Nexus Office\" as opposed to the way through immigration for those who are already Nexus approved."^^ . . "0"^^ . "5"^^ . . "2014-07-12T00:00:00"^^ . . "0"^^ . "21"^^ .
