Hence the problem throughout this thread... every agent has different rules or does not know the rules.

Some agents may indeed not know all rules, or interpret them differently and that can cause problems. Also, sometimes an agent's discretion to overlook something maybe interpreted as it being "the rule" and this can cause confusion as well.

The rule is a Canadian citizen shall be allowed to enter if an officer is satisfied following an examination that the person is a citizen. The "Place of Birth" field on a foreign passport can be one piece of the puzzle used to satisfy an officer, but a citizenship certificate, being proof of citizenship, is much better evidence.

I don't think that is reliable. You could have been born to parents who were diplomats or military of a foreign country (children born to such aren't entitled to Canadian citizenship), or if you are old enough, lost citizenship before the 1967(?) citizenship act came into effect.

I had thought of that, which made me think it was funny that's what the agent told me. Regardless, I always travel with my citizenship card when using my Irish passport, despite what she told me.

Even the citizenship card may not be accepted as proof of one's current status as it can be revoked. Only a valid Canadian passport is trusted as evidence for claiming entry as a Canadian citizen. If you are traveling on the passport of another country then the rules for citizens of that country apply. If there is a visa requirement, then there could be a problem if you lack it.

Like I've mentioned before on this thread and others, if Canada would only get with the times and issue second passports like the US, Europe and Oz do, I'd never have to worry about this, since I only travel back to Canada on my Irish passport when my Canadian is in for visas. I don't know how Canadians are able to get any frequent business travel done with only one, it would severely limit my ability to conduct business.

Though my personal favorite (sorry if its a little OT) is how up until a few years ago, there was no way to "renew" a Canadian passport other than to follow the same procedure as if you had never had one before. The part I'm referring to, of course, was that your then currently valid passport which you were replacing was not acceptable as a document proving your citizenship. You know something is wrong the passport office doesn't accept their own passports as a proof of citizenship.

I was told by a border agent that I must always enter the US as a declared US citizen -- they want to hear the declaration. Once when crossing I didn't take my US passport and was asked, "what is your status in the US." After answering, "citizen" the agent said, "prove it!" He then informed me that I could be in "big trouble" by declaring and not proving -- I told him that I was merely answering the question honestly but intended to travel as a Canadian. Apparently that is not adequate.

Our son recently received his US citizenship and we called about updating his NEXUS information to reflect his US birth cert and passport. We were informed this could only be done at a point of entry office and therefore had to go to YEG to make the change. We went to YEG and they made the change there.

The fine print for NEXUS seems to indicate it is the user's responsibility to update any information that changes -- however the US agent updating my son's profile at YEG said the system would have flagged him at the next use had we not updated his passport information and would have just made us update it as we cleared customs in the back office. Oh bother!

I don't understand why they can't just integrate the issuing office system with the NEXUS / border clearance card information.

IMO, the officer was right. When you went with your Canadian documentation and not your American, that means you aren't given the rights of a US citizen, you are given the same rights a Canadian citizen traveling in the US has.

I don't believe legally, you have to travel on your US passport though. As I said above, US allows, but does not recognize, dual citizenship. That means you can either choose to enter as a Canadian, or as an American, but not both.

Of course, legally and what they want you to do can be two different things. My mom, who is also dual, has had an officer or two who wasn't happy when she would sometimes travel on her Canadian passport into the US when her city of birth was an American one. She basically got told a couple of times that she should travel to the US on her American documents, but think it was more about US pride and patriotism then about legality, as they didn't have a problem letting her through.

It's not fine print - its pretty clear in the regular print in the Nexus guide that you have to update your information if it changes. The officer who you did your initial interview with should have told you this before you left the office as well. Theoretically, you can lose your Nexus privileges for not doing this. You are even supposed to update your employment status/employer if that changes.

The passports are the most important update, though. Unlike other documentation like your DL, your passport is able to be connected to your Nexus in such a way that you're Nexus is automatically flagged if a passport connected to it is no longer valid (i.e. expired, reported lost/stolen, etc.).

are there any special security line in the transborder area of YYZ for NEXUS users?

i know there is for domestic, but i am not sure about transborder

No.

Only if you have an AMEX Platinum card.

Is the AMEX Platinum card line shared with AC/Elite and above + *G?

No.

i think i have to correct you on that.....

According to AC.com and GTAA (older press release)

Its available for Transborder as well..... I believe (based on my experience with the Domestic side) its the same line as the AMEX Plat

I guess I got my answer here regarding NEXUS security line...... http://gtaa.com/en/news/torontopears...0-6a0101e35f47
