Sam, your case seems complicated due the legal re-org your employer seem to have done, as IRCC analyst has identified. I feel you should better speak to a proper immigration attorney with sound legal knowledge on these company laws, not a random RCIC. That legal person might be able to tell you more accurately which document IRCC might be expecting in your scenario.Thank you for the detail response. I took letter from emlpoyer and provided Canadian Business registration number as well as address of other canadian locations. infact letter stated that we havemain Head Quarter in Michigan USA and provided that address also in the letter along with company website link. reason per GCMS they said "unable to verify company as company closed Canadian Operations in Oct 2022" for which letter also states reason for the closure and what I did after that closure.
I will check if they can provide me with something else as my compan got took over by big company so in that letter they mentioned parent company name also.
do you think should I wait for IRCC to ask if they needed any further documents and then reply as they might be satisfied what I have provided as a letter on companty letter head.
I personally feel you have submitted to IRCC all you humanely could. I see there is no point in troubling your employer asking for more letters without knowing what IRCC exactly wants. However most of us in these forums are not legal experts to give you 100% assurance to point to the exact needed document or detail IRCC needs.
If I were in your situation I would have taken legal advice by now and not hesitate about the associated costs.
