Given recent conversation, a REMINDER: Cutting-it-close is RISKY.
Scores (if not the majority) of PRs reporting serious status-related difficulties in this forum, ranging from 44(1) Reports, long delays in PR card renewal, and denied PR TD applications, quite adamantly report being in compliance with the PR Residency Obligation, but were cutting-it-close. And then there are those who were cutting-it-close and encountered compelling reasons to be abroad longer than planned, who then were in breach of the PR RO (more than a few wondering why H&C reasons do not save their status).
After the fifth year anniversary of the day the PR landed, a PR needs to have been present in Canada for at least 730 days within the preceding five years, as of EACH and EVERY day. BUT this is merely the minimum and while not exactly an ABSOLUTE minimum, it is close to being a fixed, definitive cutoff.
Make no mistake, those who proceed, as if being in Canada 800 or even 900 days (less than half the time) within the preceding five years will suffice to safely maintain their PR status, are taking chances. The purpose of granting PR status is to allow an individual to settle and live PERMANENTLY in Canada. Patterns of absence contrary to that purpose will, obviously, invite elevated scrutiny and, depending on the circumstances, potential difficulties, not the least of which could involve IRCC skepticism in assessing the PR's evidence of presence in Canada, making it more difficult to meet the PR's burden of proving days in Canada. In this regard, another reminder is warranted: if presence is questioned, entry and exit dates directly prove only presence on those specific dates, not any days in-between.
This is NOT to say that IRCC imposes an unreasonably high bar for such PRs. Actually, IRCC leans more in the direction of flexible, even liberal. Proof of 731 days presence will indeed suffice. What years of anecdotal reports in this forum (and others) reveals, however, is that scores and scores of PRs grossly over-estimate the extent to which just coming to and being in Canada for 730 days supports their case, failing to recognize the import of having direct and objective evidence to show actual days in Canada, the ability to meet their burden of proving compliance with the PR RO.
This is also NOT to say that cutting-it-close typically results in the loss of PR status. There is an increased risk of that. But the bigger and more common risk, the problems scores and scores of those who do cut-it-close encounter, are problems like those related to hampered travel while a PR card application wallows in Secondary Review, or needing to apply for health care or a drivers license without a currently valid PR card.
Obviously, those who cut-it-close and then encounter contingencies in life which result in actually falling short, are indeed at high risk for losing PR status. And over the years, the anecdotal reports reveal this happens rather often and despite, as the adage goes, the best laid plans.
