Because your son is a PR, he will not be denied entry into Canada by CBSA, but his leaving is not without risk.
It is possible that he could be issued a 44(1) report for not being able to meet his Residency Obligation (R.O.), but even then, he would be admitted. If this happens, it would be the beginning of him possibly losing PR status, but based on your reasoning for why he will not be in compliance, could be strong H&C grounds, in my opinion.
Best option is for him to remain in Canada until he has accrued at least 730 days. Is that more important to you and your family than leaving for a traditional ceremony? Only you can make that decision.
Good luck!
Hi, Thank You for your response. The ceremony is very important for my family as it would be the last one of its kind and the most difficult part for us is that we dont have close friends or relatives around here who could take care of our boy for the two weeks we are gone from December 23, 2023 to January 8th ,2024. So, that leaves us with the only choice of taking him with us. Also, since me and my husband continues to remain as PR as we fulfill the Residency Obligation, how/ when can we get our child back to PR status?
