Topic is my question. Will I submit my US passport at the time of application? Do they already have those records internally?
At time of application the applicant submits copies of biometric pages from all relevant passports and travel documents.
IRCC may request, later in the process, a copy of all passport pages, or require the applicant to present the original during an interview.
Of course IRCC has a good deal of information regarding PRs applying for citizenship, "
internally" one might say, and access to additional information maintained by other government agencies or institutions. The latter includes access to a client's CBSA travel history (at the least a record of entries into Canada). Nonetheless it is the applicant's responsibility to provide a complete and accurate travel history, and IRCC primarily relies on other sources (which can also include search of "
open sources" like social media; LinkedIn is among the more common sources IRCC has been known to consider) to determine if the applicant's information is complete and accurate.
That's it? "I promise that this information is correct and I'm not completely making these numbers up"? That's very generous but I assumed I'd at least have to submit scans of my passport pages again.
If IRCC perceives reason to question the accuracy or completeness of the information provided by the applicant, such as where it identifies a discrepancy between the travel history reported by the applicant and another source of information (such as the CBSA travel history), that can trigger RQ-related non-routine processing, ranging from various versions of RQ (Residence Questionnaire), from so-called RQ-lite (asking for a few documents) to the full blown RQ (requiring the applicant to submit a broad spectrum of documents and information), to investigatory referrals to CBSA's NSSD to conduct more extensive background screening.
The burden of proof, as to days actually physically present in Canada, is squarely and completely on the applicant. IRCC does not use its access to other sources to meet the proof of presence requirement. It uses its access to other sources to verify the applicant's information, and again if there appears to be a discrepancy between the information IRCC accesses versus that reported by the applicant, it is the applicant's burden to prove actual presence.
Thus, for example, while the physical presence calculator relies on an inference that a PR is IN Canada all the days between a known date of entry and the next reported date of exit, if and when the applicant's information is subject to question, the applicant may be required to provide objective evidence to prove actual presence between the known date of entry and next known or reported date of exit.
