AND WORSE . . . sometimes much worse.Look, there are people on this board who give credible information. There are some whose information is not credible.
For someone in the OP's situation, remaining silent is about the worst possible approach they could take during a Port-of-Entry examination. The burden of proof is on the PR. The absence of key evidence, like what the PR attests to, will for sure hurt more than it helps, but make no mistake, it can slam the door shut hard.
To be clear, being uncooperative could delay formal proceeding with a 44(1) Report and Removal Order. Maybe even delay it beyond a period of being detained at the PoE to more thoroughly vet and verify the PR's identity and status. So the PR gets to proceed into Canada (after a half hour, or three hours, or at least within a day or three) without being issued a Removal Order . . . BUT at best, at the very best, all this approach really accomplishes is dramatically increasing the risk that there will be a severely negative outcome.
Some assertions are irrelevant, unreliable, foolish, or simply wrong. Some are downright stupid. This ain't about a box of chocolates.
Some further context for @ishaannayyyar:
This is among those uncommon reports I previously mentioned, about just being questioned about RO compliance by a PR only a little in breach. No 44(1) Report. It is a reassuring report. It is a report consistent with anecdotal reporting here generally.Chances of you being reported are quite low. I was in a same situation in 2018, was short of residency obligation by around 8-10 days. I was sent to secondary and was let go with a warning. They do ask you to stay in the country for 2 years straight so as to conform to residency obligation.
I do not recall other details in the situation reported by @IndianBos but among similar reports the typical scenario involves a PR arriving at the PoE after an absence for nearly if not more than three years. Remember, if a PR arrives at the PoE more than three years since the PR was last in Canada, that is on-its-face almost conclusive evidence (subject to credits not relevant here) the RO is breached: it is impossible to meet the RO if the PR has been outside Canada for more than 1096 days in a row.
That is, in that scenario, where the PR has been abroad so long since the last time in Canada it is more or less blatantly clear there is a likely RO breach, the border officials are effectively mandated to address the PR's RO . . . and as often reported in this forum, many PRs not much in breach are nonetheless waived through, with or without an admonition, almost certainly with a note made to the file.
It is also worth noting that the RISK will vary depending on other circumstances (not just the more obvious ones, like not answering questions increasing the risk dramatically). A PR just a little in breach while still within the first five years probably has a significantly lower risk than someone who has been a PR for much longer and who has continued to be outside Canada not just more than in Canada, but so long as to be in breach of the RO, even though just by a little.
Among the unspoken factors, the extent to which the PR "deserves" to keep PR status should not be underestimated let alone overlooked. Yeah, that's a vague factor, prone to subjective discretion. But no advanced degrees in political science or psychology necessary to forecast the trajectory if the PR refuses to answer questions. We ain't talking about a box of chocolates.
