Hi everyone. Planning to apply for citizenship but I don't have a dates when I leave and arrive to Canada (all my vacation trips) Old passport with embassy.
This is a double whammy.
If you cannot submit the old passport and cannot present it at the time of the documents-check interview, that in itself tends to increase the risk of non-routine processing, and depending on a variety of factors may risk a skeptical approach by IRCC processing agents. You have a good reason for not having the passport, which helps in that at the least that takes away suspicions about a nefarious motive for not presenting the old passport. But it nonetheless leaves a gap in what IRCC considers to be very important evidence/documentation. The burden of proof is on you, the applicant, so the absence of important evidence hurts your case, makes it more difficult to make your case.
A complete and dated copy of all pages of the old passport, verified at least as to it being a complete and correct copy as of that date, made before sending it off to the embassy, could have avoided that problem. Probably too late now.
And then there is the problem of accurately and completely reporting all dates of travel if you failed to keep records of your travel. (Which is something I do not understand, since it is important information for multiple purposes, even just for purposes of proving compliance with the PR Residency Obligation, but it nonetheless appears to be a rather common failure by all too many PRs, unfortunately.)
If, as suggested by
TickleMeElmo, you can reconstruct the dates of your travels so that you can get real close to accurately reporting the dates for all trips (you need to be able to at least identify all trips even if you get some of the precise dates wrong), you can go ahead and apply. Depending on how confident you are about reporting the dates accurately, you should probably acknowledge if you are estimating some dates. If you pursue this course, be sure you have a larger than usual margin above the minimum and that you can affirmatively document, if requested, what you were doing, including when and where, for days in between reported travel dates.
The other option, as also suggested by
TickleMeElmo, is that you can simply wait to apply for citizenship long enough that your available passport covers a period of time which encompasses 1095 or more days in Canada, so the validity of your application is not dependent proof of dates and presence prior to your passport. (While it was for very different reasons, I waited nearly two years beyond the date I became eligible for citizenship to avoid possible, seemingly probable issues at the time, and I am confident I made the right decision.)
