This process to gain your Nexus status card can be a tedious one but it can be all worth while in the end.
This office location at Pearson airport Terminal 1 departures level in section 8 was the final step from creating an online GOES profile, paying the 50 dollar (Canadian dollars) enrollment fee and to being interviewed in person along with our enrollment document (acceptance) and all pertinent documentation.
The process is honestly not difficult. What took the most time was finding out that we were accepted and booking the appointment for the interview. Apparently if you're in a hurry and don't want an appointment that is months in advance you can try booking at Fort Erie or some other border crossing that isn't Toronto Pearson airport. Pearson is supposed to be very busy so we waited about 3 months for this interview.
Besides presenting your documents and being asked questions there is also 2 steps to recording your biometrics which were retina and fingerprint scans. The entire interview took only about 30 minutes for both my wife and myself in which we interviewed the same two agents side by side (one American and Canadian).
The procedures for use are explained in detail and the agents made sure to explain everything thoroughly.
The enrollment expires on your birthday but it's good for 5 years at which point you can renew online or at the office. If there any changes to your status, address, information etc they ask that you come into the office to update it and that can be done without an appointment.
I'm looking forward to traveling with this new status and to having things much easier at the border and airport.
