Dear Amansethi86,Thanks sir for your precious information.
I would like to highlight also that in COPR it is written married as we have headed for divorce proceeding after we received COPR and visa. Does this may create any problem while landing. Can we correct the marital status at CBSA border after landing. Please guide further to conclude
CBSA or IRCC doesn't decide if you are married or not, it is the court's order either from your country or from Canada. Remember "You are married until court decides to divorce" doesn't matter if you are separated or not, your status on COPR as Married is not wrong as long as you are not divorced. But once you get the divorce from the court then you need to send your COPR etc. back to IRCC to get it fixed along with proper documentations. I would assume why IRCC is not responding to your requests.
I would suggest you try to patchup and bring your spouse alonwith you to Canada if he or she agrees. I am not saying because of him (I am assuming Husband) rather for your little ones (they have not done any crime to grow up without their father). After arriving in Canada if you reconciliation doesn't work then it is not at all difficult to get a mutual divorce here in Canada.
Thanks and Best Regards
