It can't understand the reason behind the significance IRCC puts on physical presence from Canada ..
Agencies like IRCC have a mandate to apply and enforce the law. The current law requires a PR to be present (or be entitled to credit as if present) at least 730 days within the preceding five years.
IRCC is compelled by law to enforce this. In the general yet practical sense, Canada is a nation governed by the RULE OF LAW, so of course actually applying and enforcing the law not only has much significance but is an important priority. Indeed, in short, that is what IRCC does, as in apply and enforce Canadian immigration law. Including the PR RO.
I could offer a partial, somewhat shallow explanation, together with some probable speculation as to the reasons and relevant policies, as to why Parliament enacted the PR Residency Obligation, largely reiterating what should be rather obvious. Recognizing that immigration policies are complicated, involving a wide range of complex and interrelated factors, objectives, priorities, and contingencies. Just matters related to WHO is granted PR status, for example, is itself a very complex subject involving, just on the surface let alone getting into the weeds, policies about attracting skilled workers, accommodating refugees, and facilitating family unification, with due consideration for the impact of immigration on communities, the workforce, as well as the availability and cost of essential and non-essential government services, locally, provincially, and nationally. It is COMPLICATED.
However, the primary reason for the PR RO, as articulated by the IAD and Federal Courts, is simply that the purpose of the grant of PR status is so that individual can
PERMANENTLY settle and live in Canada; thus, PRs are expected to actually settle and live in Canada. There is, nonetheless, a liberal and generous allowance for time spent abroad so that PRs can attend to all sorts of various matters that might compel them to spend time abroad. Close family illness for example. As the IAD and the Federal Courts have oft emphasized, the PR RO is very generous. An individual can actually spend a lot more time abroad (up to three-fifths overall) than in Canada and still maintain
PERMANENT RESIDENCE status in Canada.
For you, for any PR who has applied for a new PR card or who is abroad and applying for a PR Travel Document, or who is otherwise being examined by IRCC or CBSA (such as in a Secondary PoE examinations when entering Canada) as to compliance with the PR RO,
the key, overriding question is that posed by @zardoz:
A valid question at this point might be "Were you, in fact, in compliance with the Residency Obligation requirements, when you submitted the application?". If not, you may be in for some "interesting times".
As
@zardoz alludes, if you are not in compliance with the PR RO, dealing with this is what is important.
And, if my previous post did not make it clear,
if you are NOT in compliance with the PR RO, the odds are that a request to withdraw the PRC application will NOT stop IRCC from proceeding with the residency determination.
