Thanks for quoting; I have emphasized the points here that seem to be what you are missing: that although the government in many different ways says you "should" have exact identification (often stating this as 'must'), this is actually not true in statute.Upon arrival at a Canadian port of entry, travellers must satisfy a CBSA border services officer (BSO) that they meet the requirements for entry into Canada. For Canadian citizens, permanent residents and persons registered under the Indian Act, this can be done through questioning and through verifying documentation such as a:
As this part clearly says: for citizens and PRs, they can meet the requirements by undergoing questioning and checking of documentation; they even say "documentation such as", meaning none of these individual things are hard requirements. (Even if strongly recommended, including by me, to carry the best documentation possible).
Which is precisely what I have been saying.
For those who 'know stuff' about this topic, none of this is a surprise. The fact that you keep throwing up more sources that do not contradict what I'm saying - you're just demonstrating that you do not.
Or in more simple terms: there is signal, and there is noise. You are noise. Readers can decide for themselves which of those to, ahem, attenuate.
