If you are talking about the "residency obligation" (something necessary to maintain PR status) as opposed to the "physical presence requirement" (c.f. citizenship), is that documented somewhere, because I can't find any document that says minors do not need to meet that requirement?
I tried finding anything specifically about minors and residency obligations and couldn't find such a thing on the IRCC site, except the
PR card renewal information, and
something similar in their help centre (excerpting only rules that mention children):
...you must live in Canada for at least two years within a five-year period...
Time spent outside Canada may also count towards the two years if you are:
- a dependent child travelling with his or her father or mother who is a Canadian citizen,
It may also count if you are:
a child travelling with his or her father or mother who is a permanent resident
and who works full-time for:
- a Canadian business, or
- the public service of Canada or a province.
The fact that there are specific clauses for children with PR status who accompany (one of) their parent(s) to me suggest that the residency obligation does apply to children. Similarly, the
renewal forms for PR cards do not have specific clauses for children to exempt them from any of the residency obligation requirements, again strongly suggesting that the residency obligation does apply.
Looking at the
IRCC operational instructions (for citizenship) the requirement is that PR status must have been maintained (emphasis mine):
Permanent resident status is verified for all minor applicants and that status must have been maintained and there must be no unfulfilled conditions under the Immigration and Refugee Protection Act related to their permanent resident status.
which again implies (but does not outright state) that the
residency obligation must be met, also for citizenship.
Now,
@Canadiancoming 's son likely meets those requirements, because the rules require a PR to be able to get to
730 days in a 5 year window. The son was allowed in the country 1.5 years ago, so at that point he was assumed (by the CBSA officer) to be able to meet that presence obligation. There's no reason to assume that has ceased to be the case. The fact that there is
no physical presence requirement for citizenship means that just being able to meet the residency obligation is sufficient in a concurrent application for citizenship for a minor.
