The whole point is one needs to inform IRCC in case of any circumstances change (Marriage) after you have been issued a COPR. In my case, I was single when I was issued a COPR. However I got married after COPR but before landing. In which case, I am required to raise a webform to communicate IRCC regarding the changes and wait for their instructions.
This is not optional, it s mandatory to communicate these changes and yes the expectation is that IRCC will examine my spouse and add him as my dependent and further reissue new COPR's for both of us. This is basically to ensure that your spouse is admissible to Canada, which has a direct impact on the principal applicant's admissibility also.
If I try and land on my existing COPR, then the status on my COPR (Single) is not matching my actual status, which could be interpreted as misrepresentaion in the event that my spouse has not been declared already.
I understand your point and yes i agree it is mandatory to inform IRCC after change of status. My point is, final decision was made prior to change of status, and you did your part to inform IRCC and no way this is misrepresentation. From my personal experience, with current backlog it takes time to get response, and quite often it is generic reply.
Since you haven't heard anything from IRCC and I guess you dont have time, You can go ahead and complete landing procedure, and put an application to sponsor your spouse. You dont have time since your COPR will expire soon....If you are looking for advice, this is the one and totally within the guidelines.
If you continue waiting, with no reply until your COPR expires, then you need to submit new permanent residence application, pay all the fees and meet any requirements in effect when you apply again
