I respectfully disagree with both corrections:
There is no point in providing info on travel documents that you haven't used to enter Canada.
As I suspected,
Natan was referring to travel documents which need to be included with a citizenship application (and then presented at the interview), rather than in making unnecessary ATIP requests looking for information the PR should already have.
And for now that would indeed be any and all travel documents which the PR has possessed
within the relevant time period, which is since landing or during the previous six years (if landing was more than six years prior to making the application),
including expired or cancelled travel documents (if they could have been, in any way, used during the relevant time period). And whether or not the individual used the travel document. The required submission is for any travel document the applicant might have been able to use, not just those the applicant did use, and thus
it is irrelevant whether the travel document was used to enter Canada or not.
The OP's query, after all, is whether the absence of stamps in the passport might cause concerns during the documents-interview check.
Note, otherwise, that beyond wasting taxpayer money, obtaining
travel history or records of exits and entries from the government can
NOT be relied upon to be complete. They are almost always
accurate, as to those border events identified, but not necessarily complete.
While the government records are increasingly complete, again they cannot be relied upon to be complete. There is
NO reliable substitute for PRs keeping complete, contemporaneous records of all international travel, including day trips to the U.S. There is only one person in the world who can reliably record each and every trip a person makes abroad, and that is the person himself or herself. He or she was there, in person, each and every time.
And it is easy to guess who pays the price for any discrepancies or omissions in the travel declaration. No matter what sources the applicant used to populate the exit and entry dates. No matter what excuses might be available. The applicant pays the price for errors and omissions.
Thus, for example, all citizenship applicants should be aware that if they obtain the CBSA travel history, any other Canadian records of entry to or exit from Canada, and perhaps all U.S. records of entry into the U.S. as well, just because a trip does not show up in those records it would be a mistake, indeed a misrepresentation, to not declare the trip.
Remember, IRCC can research and investigate a wide range of sources (and on more than a few occasions has), looking for any information which might controvert an applicant's declarations. Among the more noteworthy examples (from official decisions regarding actual cases) is a case in which CIC (before the change to IRCC) considered a conference flyer which indicated the applicant was among presenters at a conference in Switzerland during a time the applicant declared he was in Canada. Did not go well (it was not the only discrepancy in that individual's case; nothing in the decision indicated how CIC obtained the conference flyer). In another case, CIC relied on LinkedIn account information showing the applicant to be employed abroad during a time the applicant declared to be in Canada -- in this case, the name on the LinkedIn account was not the applicant's name, but was a name CIC had determined the applicant sometimes used (note, there are several cases in which CIC/IRCC has researched and used LinkedIn account information against applicants). And of course, documentation submitted by the applicant can be scrutinized for inconsistencies (more than a few cases have focused on location of credit card transactions, including transactions apparently in Canada when the applicant reported being abroad, and the converse),
and remember inconsistencies which potentially indicate presence in Canada during a period the applicant reported being outside can also be used
against the applicant, despite the fact that such information superficially indicates additional presence in Canada (among Federal Court decisions illustrating this was the case where an applicant submitted school attendance records for her children, which included dates of attendance, in Canada, during a period the applicant said she and her children were abroad . . . she was denied citizenship, and this was big factor against her).
