When I did my interview I was told explicitly that as a trusted traveller it was my responsibility to initiate the conversation and voluntarily declare any items (or state I have nothing to declare). Of course, this first time entering the US by car I pulled up to the booth and started off by saying I have nothing to declare. The (US) officer was taken aback and still went through his top 10 questions, including asking if I had anything to declare (no), if I had any alcohol or tobacco (no) and if I had any food (no). I remember thinking to yself, what part of "I have nothing to declare" don't you understand. From that point on I made a point to let the officer lead the questioning. And in 98% of the cases, this works. However, recently, when entering Canada by land @ Sumas (BC lower mainland), there is one old guy who works the Nexus Lane and I think he firmly believes it his personal mission to pull Nexus cards as a job security measure (i.e., less users = more need for Regular Lanes). This guy is a total jerk. He just sits in the booth until you say something. Then when you start off by saying "I have about $200 worth of stuff" he barks out "What is stuff and what do you mean about? Don't you know what the items are and what they cost?" He is the only person who has ever referred me for secondary and actually threatened to pull my card (BTW when the secondary person talked to me they just rolled their eyes and went through the motions). I know other people who have had him as well and make the same remarks. So, bottom line is YMMV. As I said, most officers are 98% a positive experience and guide the conversation but there are some bad apples out there.

I have my wife's and mine appointment scheduled for September. There's a a appointment sooner to a location closer to us. Can I book one of ours and we both show up together?
I doesn't show how many spots open.

It only shows the first appointment available when you first go to the "schedule (or reschedule) appointments" page, but when you click the date, you will see if one or more additional appointments are open on the same day.
You can also switch to week or month view. In whatever view, the time periods with availability are shown in different shading than unavailable time periods.
If you get two appointments on the same day, they don't need to be consecutive. They see families consecutively (or together) as long as they had appointments on the same day. BUT YOU MUST EACH HAVE AN APPOINTMENT.
When I was looking for a cancellation to move up the appointment for my daughter, there was a block of five spots for the next day. A whole family was unavailable on a Saturday of a long weekend, making five other people happy. So don't despair - cancellations come in groups as well as individuals. Keep looking if this one only has one spot.

GOES email notification app. status change
 

I did not realize that I would receive notification of change of status of my renewal, I had been checking my account every few days. However, I did receive an email this morning which was nice.

For those in the renewal process:

Renewal application transmitted June 8th.

Renewal approved August 10th (and notification of change in application transmitted same).

No interview required. And that was with some changes in my profile including change of province of residence, DL change along with that, and change of employment status from employed to retired. Nice.

Letter states Global entry can be used immediately and Nexus once card received and activated, which is even not an issue since my current Nexus membership is good till October.

Very smooth and efficient.

So why not report the guy here:

right, it was only showing a 7:20pm opening for that day. i didn't want to reschedule mine to that day and time not knowing if i could do same for my wife for same date and time. That's why I was wondering if I booked mine for that time, and couldn't do same for wife, could we just go together anyway and would they see both of us?

Curious that a Canadian citizen re-entering Canada by air requires a Canadian passport? A drivers license (enhanced or otherwise) or birth certificate (or naturalization card) are not enough?

Tossing in another "waiting time" data point - I applied (first time application) June 3, received conditional approval this morning Aug 10, so just about 10 weeks for conditional approval. An appointment opened up at YYZ for tomorrow, so waiting time from conditional approval to appointment ends up being about 26 hours and I get to take a scenic Sunday drive. :)

The AC web site confirms this (and also confirmed by an email response on this question to me by AC)- that the nexus card can be used to either check-in or board the plane for either domestic or transborder flights.

Which Canadian airports with US preclearance facilities have the new Global Security machines whereby the nexus card as well as the passport would be recognized? I am also asking about the connecting lanes as well as the direct entry to US preclearance lanes?

But it takes forever for the agents to figure out how to process it.

It would be "off-book" if the agent saw you both, although I am sure that it has happened a non-zero number of times. I am also sure they won't commit ahead of time, by any medium, to do it, and I am sure I've read upthread of people having the same hopes dashed.

Your choices (1) are to wait for two same-day openings and be 99% sure you will both be seen at the time of the first appointment, regardless of whether one appointment is at 9 am and the other at 7 pm, or (2) take your chances that you both go on the earlier date with just one slot, and one of you does not get the interview that day, and has to make a second trip on a later date. End of the day, the gamble is not a bad deal. You wait just as long for the second card as you would by leaving both appointments on the same day, but one of you gets their card sooner and could use it on your own travel in the mean time, the second person knows the drill ahead of their turn, and you're only out the cost of the second round trip, which obviously varies with where you live and where the interview is. Mine was at YYZ so the parking cost me $22 (half what the card did!) whereas my daughter's was in Ft Erie, so we had to drive half a day there and back but parking was free. If neither of you plans to travel alone, then the benefit of getting one card sooner is nil, but maybe you would be the rare beneficiary of someone having a good day.

Bottom line: no sure thing, never promised, may have happened: your gamble.

The DL and Birth Cert stopped being acceptable in 2009, I think it was.

I was under the impression that a Canadian could always get back into Canada with or without a passport. In other words, Canada cannot refuse entry to any of its citizens. I've never tested this and haven't seen the exact rule allowing it, but a coworker recently had her passport stolen at CDG just before returning to Canada and had no issues whatsoever. I guess her DL and distraught appearance over having her travel wallet stolen were sufficient for the border agents.

Can someone confirm that these are the only documents that I need to bring to my interview:

1. Passport
2. Driver's License
3. NEXUS Conditionally Approved Letter
4. Bank statement with current address (just in case)

I only mentioned my passport and DL in the application. I've been reading about people having to bring their birth certificates, so I'm a bit confused.
