Thank you so much for detailed explanation!You have to understand two things:
1. Flagpoling is no legal word. It simple means going to the border and turning back without entering the US. When you went to the US border but turned around, you simply withdrew your application to enter, and thus there was no refusal. This is called administrative refusal, where the person withdraws their application to enter. An administrative refusal is you withdrawing your application to enter the US. It is not a visa denial and neither is it a refusal. Also, you were not fingerprinted, nor were you subject to admission examination.
A US visa refusal, even if it happens, has no impact on your Canadian PR, unless you committed a crime, an immigration fraud etc. Since you did not enter the US, you do not have to enter it in your travel history.
As regards disclosure, when you never filed an application to enter, and no determination was done, it is not a refusal. Eg. IF you file your application for Canadian PR, but then withdraw it, it is not refusal
However, if you fly to the US and are asked to turn back in the next flight, when you tray and cross land border, are stopped and asked to turn around, all these will count as refusals. Most applicants who flgpolling don't even have a US visa. They merely got to the border and turn around. Usually you can turn around before you reach the US border, but if in case you reach the border and inform the officer that you wish to turn around, it is merely withdrawing your application to enter.
2. All your visa refusals should be declared in your application, not doing so can lead to misrepresentation. As per law you have an obligation to be truthful. Section 16(1) of the IRPA states:
- 16 (1) A person who makes an application must answer truthfully all questions put to them for the purpose of the examination and must produce a visa and all relevant evidence and documents that the officer reasonably requires.

You said we don’t need to write a flagpoling under travel history. However, what do you think about writing a flagpoling for citizenship application? I guess we supposed to because we left Canada, but we never entered US. This is so confusing.
