Not weird. Not even unusual.
While
@iceman55 mostly covered things, I differ slightly in regards to the characterization of the request for information and documents covering, in addition to the full eligibility period, up to the present (which would be the date you submit the CIT 0520 response); from what I have seen "
to present" requests are not unusual even though requests covering only the eligibility period (or less) are probably more common.
There is a tendency in this forum to extrapolate general practices, sometimes even the rules, based on individual experiences. Why such utterly poor logic persists baffles me. What happens in individual cases ONLY indicates what might happen, based on extrapolating what *can* happen based on what, at least in SOME instances, has happened. Far, far more information is needed to extrapolate trends or patterns beyond that, beyond extrapolating what might happen, let alone to draw conclusion as to what the norms are, let alone what will necessarily happen in individual cases.
Most RQ-lite requests (using CIT 0520) we see reported in the forum are limited, not as broad or expansive as yours (and a couple others recently referenced in the forum). Many of those reported here are requests for very specific documents, often covering only a very limited period of time, not even the full eligibility period. The actual scope of the requests varies widely from individual to individual.
Moreover, these requests are usually generated in the local office, and there can be wide variation in the policies and practices comparing one local office to another.
And it warrants taking note that just recently there has been a sudden increase in reports from applicants getting the CIT 0520, after a long period (years now) during which we saw rather few getting CIT 0520 . . . not too long ago I recall someone posting here that these requests were "
rare" these day . . . but then, abruptly, there are suddenly more in a few weeks than previously seen for a period of several months. This may be merely coincidental. Or it may be the first indications of an effort by IRCC to engage in broader quality assurance screening.
So, as
@iceman55 suggested, just getting this does not mean there is reason to worry . . . the odds are this is about verifying the information in your application, eliminating questions. It does not mean there is any significant concern let alone serious issue.
That said, YOU know your case, you know it better than anyone at IRCC. If there is a problem the odds are very high YOU already know what that likely is.
There should be NO PROBLEM if you were qualified for citizenship when you applied, and you properly completed the application, honestly providing accurate and complete information as requested (in the application and in response to subsequent requests), and your documents reasonably support your claims about where you have lived and worked, and are consistent with your travel history, and you continue to meet the requirements for citizenship (no criminal charges, no prohibitions, in compliance with the PR Residency Obligation).
