This conversation is OFF-TOPIC here. Colouring way outside the lines. But the underlying issues, and misconceptions, are relevant to IRCC processing generally, thus citizenship processing as well, and are in particular relevant to misconceptions about IRCC's processes in verifying client accounting of presence or residency in Canada.
It warrants noting that the main problem with PR card renewals appears to be user-based. For some strange reasons, similar reason perhaps underlying why this conversation is taking place here, where it is OFF-TOPIC . . . so many clients fail to colour inside the lines.
I will (I expect) address some aspects particular to PRC application processing, but first will address matters common to both PRC and citizenship application processing.
Among the most common situations complicating PRC and citizenship applications is the extent to which clients make mistakes or fail to follow the instructions. This forum, including the threads in which PRC renewal is the subject for discussion, is rife with example after example of client error, from entering inaccurate dates to the omission of relevant information.
IRCC personnel do not have a crystal ball which will systematically correct all errors, inaccuracies, or omissions. While IRCC is doing a remarkable job adapting to and accommodating client error, so that the vast majority of those who make an error do not suffer dire consequences for having submitted information inconsistent with the facts or instructions, the cumulative impact of even small errors undoubtedly affects how long it takes to process applications.
Many errors are common errors and IRCC has clearly adapted to handling most of these without stumbling, with minimal slowing. Scores of citizenship applicants, for example, look at a passport stamp for when they exited their home country and report, in the presence calculator, that was the date they entered Canada. This can easily be off by a day or two. More than a few here will blame Canada because it did not make an entry stamp in the passport upon the PR's arrival in Canada. Many blame Canada even though the PR was there and had every opportunity to keep a perfectly accurate record of the date. Even though the PR himself or herself is the ONE BEST SOURCE for each and every date the PR entered or exited Canada. But in their application they get the date wrong. So IRCC compares the CBSA travel history and the client's account, and they do NOT match. For the majority of applicants this is no big deal. IRCC will sort it out. This submission of false or inaccurate information does not even result in non-routine processing.
But it is NOT as if IRCC can just shrug and assume the applicant's false information is a minor error a day or so off. The processing agent will need to make an effort and take the time to more thoroughly cross-check information, to more conscientiously examine and compare other dates in the presence calculation, to assess address and work history more closely and likewise compare that information with other information in the application and other information known to the processing agent. Some of these errors may trigger additional inquiries, such as some Internet searches for open source information.
The amount of time small errors add to processing an individual application still kept in the routine processing track (thus not put into another queue to wait for additional processing) may not be much. BUT it will certainly add up. If the average amount of additional time for handling SMALL errors is a mere 15 minutes, in say 20% of the applications made, the cumulative impact is likely in the range of at least THIRTEEN THOUSAND or so worker-hours a year (based on processing approximately 200k applications annually, which IRCC is likely to well exceed this year, and adding proportionate time to account for efficiency rates, which probably adds at least ten minutes for every fifty minutes of substantive work). THIRTEEN THOUSAND or so additional worker-hours a year. No math necessary, just some simple arithmetic. Just one tiny, incremental step in the process to accommodate client error, at just one step in the process. It adds up.
And again, that is for the smallest, and rather common sort of errors, the sort a very large percentage of us will make if we are not especially careful. Clue: Those who make applications without having kept complete records of all international travel are NOT careful at all, let alone being especially careful, AND it is clear their number is huge.
Then there are those who make more substantive, bigger errors. Many make such mistakes. Way fewer than the number who make the small errors, but nonetheless many thousands . . . we see scores and scores of them reporting in this forum alone. Photos not meeting specifications. Lack of proper proof of language ability. Dating the application a different date than the presence calculation. Failing to include a requested police certificate. Failing to disclose who assisted with the application when handwriting, signatures, envelope, or other indications suggest that it is probable someone did assist. Applicants declaring their home address to be a location which is inconsistent with other indications about where they actually live (many applicants use the address of a parent, or close family member or friend, for various reasons, but it is NOT where they actually live). Just scan topic headings here: there is no shortage of "oh-no-I-made-a-mistake" queries in this forum.
Then there are the scores of applicants whose circumstances are just complicated. Life is complicated. The lives of immigrants tend to be more complicated. Many will have significant periods of transient address or work history. Many are maintaining continued ties abroad. More than a few like me whose work has this or that strong foreign element (all my services are provided to a foreign client). And then there are those who have personal situations which can complicate things. When, for example, there is a citizenship application for a married person alone, separately, and no application for the applicant's partner, and it appears likely the reason is that one has been living abroad, that means the processing agent again must more closely examine the information to verify the applicant's account . . . recognizing that if a person's spouse is living or working abroad, that increases the probability the individual has also been living abroad, since married couples tend to live together. So a processing agent needs to do a little more work, take more time, to go through the applicants information and verify it. (Adding even a couple small errors to situations like this, which is common, can really ratchet up the effort and time necessary for IRCC to do due diligence.)
Then there is that (hopefully small but obviously more common than one would hope) category of client who fails to read and follow the instructions, many of whom will read something into the instructions which simply is NOT there. How many reports does this forum see from applicants who read item 10.b. in the application (10-2017 version), which asks "in the past (4) years, were you in another country (other than Canada) for a total of 183 or more days?" and then instructs those who check "yes" to submit a police certificate, and somehow get the idea that even if they were in another country a total of 183 days or more they should either check "no" or otherwise do not need to submit a police certificate? Recognizing that what we see in the forum tends to be only a small percentage, the tip-of-the-iceberg so to say, the forum reports suggest there are scores and scores of applicants who either check "no" or otherwise do not submit a police certificate even though the factual response to this item is YES.
This is just ONE example of how many applicants almost deliberately misread or otherwise do not follow rather simple instructions. (Late last year there were some forum participants insisting applicants could and even should ignore some time abroad, such as time before becoming a PR, and answer "NO" even though as a matter of simple fact the applicant was abroad more than 183 days in the preceding four years.)
The police certificate request is also commonly not properly addressed by an inordinate number of applicants who fail to add up dates they were in another country, somehow reading this as asking about staying in the other country for six consecutive months, even though the instructions and the examples provided clearly provide otherwise.
Whether the reason is the applicant acting as if time abroad prior to becoming a PR does not count (despite being within the preceding four years), or the reason is the applicant did not total time from trips in different years, the instructions are clear enough that these sorts of responses could reasonably be considered MISREPRESENTATION, with serious consequences. BUT IRCC is not interested in punishing PRs or citizenship applicants. IRCC is remarkably understanding and accommodating when dealing with these situations where the applicant falsely declares "no," when the factual answer is "yes." BUT AGAIN, THIS WILL HAVE AN IMPACT ON HOW MUCH ADDITIONAL EFFORT AND TIME will need to be spent dealing with this single applicant. And the more applicants who make this sort of unforced error, the more it adds up.
