When PR forms were filled manually more than ten years ago, I did not declare my stepson as stepson but instead simply declared him as son. Because, at that time the question on family declaration form did not specifically appear requiring him to be declared as stepson. Since then, we landed and have already spent couple of years in Canada. We now realize that this could be a mistake potentially affecting future of him and all of us. What if this is voluntarily disclosed to IRCC now? Will they accept any justification?
