The PR Residency Obligation has not changed in nearly two decades. PRs are still *obligated* to spend at least 730 days within the relevant five years IN Canada. Once the PR's date of landing is more than five years past, the relevant five years is the most recent five years. That is, days in Canada more than five years ago DO NOT COUNT toward meeting the PR Residency Obligation.
While compliance with the PR RO is a necessary element in the PR card renewal process, the renewal of a PR card has NO relevance in determining whether a PR is in compliance with the RO. As stated in the post you quote:
"If it was a renewal, it is possible that he does not meet the RO even if he has 3 years left on his card. . . .
. . . Once you have been a PR for more than 5 years, you always have to have at least 730 days in Canada in the past 5. It is not enough to meet the RO for one PR card renewal and then think it will not be looked at again until the next renewal. "
Yes, this remains true. Again, the PR RO has not changed in nearly two decades.
Thus, NO MATTER when you are issued a new PR card, NO MATTER how much longer it is valid, how much longer it will be until it expires, whether or not you are in compliance with the RO will depend on how many days you have been IN Canada within the preceding five years as of the date you arrive at a PoE returning to Canada.
This year's circumstances may lead to more flexibility, even leniency, in how strictly the RO is enforced. That is, relief for those breaching the RO, based on H&C considerations, may be broadened or expanded some. There is no hint of a general policy about this, so it remains highly likely H&C relief will continue to be evaluated on a case-by-case basis depending on the individual PR's circumstances.
Gambling on H&C relief more than a year from now would, indeed, be gambling.
RISK OF DEPORTATION:
"Will this approach result in deportation since I will not have 730 days cumulative [when I return to Canada]?"
The procedure is not so simple as to support a simple yes or no response to this question. The overall RISK is that the failure to comply with the RO can lead to the loss of PR status when a Removal or Departure Order becomes enforceable. So, yes, when you return to Canada if you have been outside Canada for more than 1095 days within the preceding five years (thus, IN Canada less than 730 days within the preceding five years), that can lead, eventually, to being deported.
The procedure is discussed in numerous topics here, from being examined at the PoE, issued a 44(1) Report for Inadmissibility due to a breach of the RO by a CBSA officer in Secondary, and then interviewed by another officer who determines whether to issue a Departure Order (sometimes called a "Removal Order"), and then being allowed to enter Canada and given 30 days in which to appeal . . . up to and including the process in an appeal, and how H&C factors are weighed.
As noted, there may be some additional flexibility or leniency exercised in the coming months, perhaps as long as a year, due to this year's unusual circumstances. Nonetheless, some basics remain true:
-- RO requires presence in Canada for at least 730 days within the previous five years (PR card dates NOT relevant)
-- best to get back to Canada BEFORE breaching the RO
-- failing that, best to get back to Canada as soon as possible, with as small a breach of the RO as possible
-- relying on H&C relief is a gamble
