I am NOT an expert and I am not qualified to offer personal advice. I should not, cannot, and will not try to advise what you should do in your particular situation. For lots of reasons. One obvious reason is that I have not reviewed the entirety of the application you submitted, and without doing that any personal advice would be based on insufficient information.
But this is not a difficult question and is one you should be able to answer for yourself. Regardless which version of the application form you submitted,
they all require the applicant to verify they will notify IRCC of any changes in the information submitted. The observations I posted above, back in August 2020, still cover this subject and that should be more than sufficient for you to answer this question for yourself.
I will reiterate one key distinction: some of the information asked for and provided in the application is historical. History does not change. Other information in the application can change while the application is pending. Applicants verify they will notify IRCC of changes. Failures to timely do so constitute misrepresentation by omission, even if this is rarely enforced.
So, information regarding work history, address history, or travel history, for example, does not change because it cannot change. Current home address, in contrast, can change and applicants are obligated to notify IRCC if this changes (even if the failure to do so often does not trigger a problem, and perhaps typically does not even result in concerns about the applicant's credibility, or not by much anyway, so long as the applicant continues to get communications from IRCC and responds appropriately).
How does this apply to information about immigration status in other countries?
Question 13 in the application varies depending on which version of the application was submitted. The most recent version, compared to older versions, being:
Current version: "13. Do you currently, or have you ever held immigration" . . . [status in another country]?
2018 version (just for example): "13. Have you ever held immigration" . . . [status in another country]?
My sense is that the change in the application form indicates IRCC wants applicants to inform IRCC if they obtain immigration status in another country after applying. I do not know, no clue actually, how IRCC responds to an applicant's failure to timely give notice of the change.
You know which version you submitted.
Probably safe to say that for applications using an older version, one of those from before this question referenced status currently, the failure to notify IRCC cannot be the basis for denying the application for misrepresentation, let alone pursuing a criminal charge. And my sense (without really knowing) is that it is not likely there will be a formal allegation of misrepresentation even for those whose application asked for current information about status in other countries; however, the failure to timely notify IRCC probably has some impact on the how IRCC officials perceive the applicant's credibility.
Overall: again, how you personally approach this is a decision for you to make. Best I can offer is that if you failed to timely notify IRCC of a change in the information you provided in the application, doing so sooner rather than later is probably better.
Collateral Observations: In other posts you indicate your spouse has a Canadian PR application pending. If you are sponsoring that application but living outside Canada, that could mean you are NOT eligible to sponsor and could jeopardize that application. Additionally, I am not certain but there is at least a significant chance that IRCC already knows about any status you have obtained in the U.S., because of the information sharing protocols between the U.S. and Canada.
