So on Tuesday, I have my Nexus interview at YYZ. For anyone who already has GE, what was the interview process like when adding Nexus? Not sure why but I have high anxiety going into my interview...

When arriving in US pre clearance at YUL, you use general public security lane which are to the left when facing security. After clearing security, the GE kiosk are on the right wall (when facing CBP inspection booths). You can activate GE kiosk using passport or NEXUS card.

When entering Canada, you will need NEXUS card to activate NEXUS kiosks.

Depends how much they like you and how "interesting" your travel history is. I was asked why I wanted it by both sides, and by the CBP officer if I had indeed listed every country I had visited on my application, and that was about it. I was an existing GE member applying for NEXUS. But it will vary for every person. That said, generally if there was anything really concerning in your history (e.g. routine, regular recent Syria visits, Robert Hanssen-esque escapdes with the Russians) you wouldn't get approved for the interview at all. If you're approved for the interview, you're really 95% of the way there. Answer the questions honestly and you'll likely be done in 15 minutes.

At YUL, as someone with a non-interesting travel history (Canada/Italy/Germany within last five years) the interview was a breeze upgrading from GE to NEXUS.

The US re-acquired my fingerprints and took a new photo for the NEXUS card (which was horrible - they need to get webcams that aren't logitech orbits from 2005). Canada asked me why I was applying [business] and then asked me if I knew how to use the NEXUS kiosk (said no).

As TheBOSman said, varies from person to person, but they can deny you rather than grant you an interview, so you're probably almost there if you got the interview in the first place, just answer whatever questions they have.

My nexus card expires on NOV 15, 2017 and I am arriving in YYZ on the same day about 8pm. Can I still use the nexus kiosk to enter Canada on that day?

Another technical question: If I am on a conditional approval and my renewal interview is scheduled on NOV 16, one day after the expiry of my card. If I got approval during the conditional interview, will the period of the new membership going to be 5 years and 364 days or 4 years and 364 days?

You can try. It may or may not work.

4 years and 364 days. Bonus time only applies to initial application, not renewal.

CBSA has updated its NEXUS document renewal page. It says pretty much the same thing as it used to, that passport updates can be done in the TTP system (used to say GOES) and that in-person visits to the office are not necessary. We all know that GOES didn't really push passport updates to CBSA, maybe the new system will.

It also says that address changes can be done at TTP System website, but the TTP website says only mailing addresses can be updated online. Physical address changes must still be done at an enrollment office.

I've already updated my kids' new passports in GOES before it was replaced with TTP. we moved a month ago, so I will stop by the office today to update my address, and ask CBSA if they can now see my kids' new passport info.

There’s really no evidence either way whether TTP is merely a cosmetic upgrade on the general public facing website or a wholesale infrastructure upgrade to include backend integration between CBP and CBSA but my guess is that it is the former and not the later.

Front desk person at Vancouver Airport enrollment centre told me yesterday that passport updates still need to be done in person, despite what CBSA says on the page I linked above.

Was he a CBP officer or CBSA officer who informed you that piece of information?

Their front desk person is none, just an employee.

Was there clarification made as to what "passport update" mean? Updating passport to update expiry and passport number or updating passport due to a new passport from a different country?

And yet YOW has said not to come in for passport updates for over a year now... it's almost comical how differently the message has been passed around.

LOL.

Pure speculation on my part but I'm guessing the technical design behind the scene involves each fully approved NEXUS member having a "transactional" record which is used by kiosks and kiosk, GOES/TTP and enrollment centre are three separate systems.

Changes to GOES/TTP or enrollment centre will update the transactional record but GOES/TTP and enrollment centre don't sync up after the initial application.

This would explain a lack of FT reports regarding "despite updating passport expiry date/passport# in GOES/TTP only I can't use NEXUS."

This would also explain CBSA officer at enrollment centre stating GOES/TTP don't get reflected (in their enrollment centre system). While what they state is factually correct, functionally, it is immaterial as kiosk are not using the "enrollment centre system" for immigration clearance.

This would also explain why CBSA website, despite recent updates to content, continue to maintain simple passport updates can be done on GOES/TTP.

I would guess you are right. The backends for CBSA and CBP are definitely separate which is why if you go to YYZ for a document update they each (CBP and CBSA) each type the data into their own PC

That's definitely not true on the new TTP site. I finally got around to getting my proof of Canadian citizenship by descent (a citizenship certificate) which was added at an enrollment center in mid-September and then a Canadian passport which I added mid-October (next trip into Canada). Both are reflected on the TTP portal. And the NEXUS machines use the NEXUS card regardless and US CBP expects you to enter USA on US passport so I've only ever used my US passport or NEXUS card at the kiosk so there's no way for TTP site to be aware of this other than the inputs from the enrollment centre.

When I asked about it at YYZ I was told that a new type of document (like evidence of a citizenship that wasn't previously on file or a passport for a country that you never had a passport on file for with GE/NEXUS) required a visit, whereas updates of an existing passport (example: Passport already on file is renewed) could be done on TTP site as long as it allowed it. However, as you said, information is conflicting from different people at CBP/CBSA.
