There are multiple reasons why the interviewer, a processing agent, and the Citizenship Officer might want more proof you met the physical presence requirement, ranging from continuing residency-related ties abroad to the extended absence after applying.
The emphasis is on they
MIGHT want more proof. They might not. You will most likely next be scheduled for the oath
IF after reviewing and assessing your information they conclude your account of days present in Canada, that is your declarations as to dates of travel outside Canada, are complete and accurate.
Chances are good there will be no problem. No RQ. No RQ-lite.
BUT since there are some reasons why they
might have questions, reasons why they might want more proof, there is some chance you will be sent:
-- a request for additional residency documents, which is CIT 0520 and sometimes called RQ-lite, OR
-- a full blown RQ, that is a "Residency Questionnaire" which is CIT 0171
These are discussed in numerous topics here. Key information and documentation typically requested includes:
-- Entry/exit records from certain countries including home country
-- Documentation showing occupant/resident interest in dwelling (household) where you have been living in Canada
-- Documentation supporting your activities in Canada during the eligibility period; this is usually to show employment
-- -- in case where applicant was not employed, such as a stay-at-home parent child care-taker, documentation to show children's attendance in school and other related documentation that is evidence of the parent and children's presence in Canada
-- Banking or other financial records which are evidence of a life being lived in Canada
Again, chances are good you will NOT have to provide this kind of information and documentation. But you might.
The reasons why an applicant might face further questions about residency or presence have also been discussed in many other topics. I do not have time to revisit all the relevant questions in detail, but here are some which might raise questions in your case:
Obviously, most married couples live together, or at least spend a significant amount of the time together, so just the fact that a spouse is living and working abroad raises a question about how much time the applicant was abroad with the spouse.
Leaving Canada after applying, or an otherwise extended absence after applying, has long, long raised suspicions about how complete the applicant's account of presence in Canada is. This is a subject which in particular is discussed in many other topics.
An Observation about Proof:
Passport stamps do NOT prove much at all. At most all they prove are those very few days the applicant entered Canada, and only if the applicant's passport was stamped for that entry. Canada does not usually stamp passports when a PR leaves Canada, so stamps in a passport rarely are proof of when a PR left Canada.
Obviously, stamps showing an entry into another country do not show when a person was in Canada. They only conclusively show dates the person was outside Canada.
Stamps showing an entry into Canada do NOT prove the PR was in Canada the next day after that, let alone a week later, let alone a month later.
In most cases there is an inference the PR was in Canada from the date of a known and reported entry to the next date the PR reports and is known to exit Canada. The presence calculator works on this principle: inferring that days in-between a date of entry and next reported date of exit are days IN CANADA.
If, however, IRCC perceives reason to question the possibility the applicant was outside Canada more than reported, the applicant might not be given the benefit of this INFERENCE. The applicant can be required to provide more evidence, more proof, that he or she was actually present in Canada during those days in-between reported date of entry and next reported date of exit. Like proving the applicant went to a job in Canada regularly. Like proving the applicant maintained a household in Canada each month. Like proving the applicant's children actually attended school regularly in Canada. Like submitting financial transaction evidence showing the applicant was living a life in Canada. Like submitting documentation which shows the applicant was not in his or her home country except as reported (this would be the Entry/exit records). And so on.
Please do NOT be alarmed by this. Again, unless the interviewer had reason to suspect you were evasive or deceitful,
ODDS ARE GOOD YOU ARE OK. It is their job to press you some when there are circumstances like yours, such as the spouse NOT living in Canada. I have gone into the detail above more to help you be prepared in case they do ask for more information and proof. They might. And passport stamps will not do it.
Good luck.
