AS far as i know, family members not accompanying at this stage do not hv to go for medical exam. I hv no kids but when i got my AIP, the letter said they will start performing security check + medical checking on my family members in home country (though i dunno how they do it), i called CIC and asked if i need to do any arrangement such as booking medical check up for my family members etc, they said NO, i dun need to do anything, they will check with our home country anyway.
Only family members eligible for sponsorship need to be examined.
If an eligible family member is not examined because you fail to disclose or the family member refuses to be examined, that person is excluded as a member of the family class for purposes of sponsorship.
If you declare the person and the visa office decides not to have them examined, then you may sponsor them in the future.
So, if you fail to declare a child on your application OR that child is not examined, then that child may not be sponsored in the future.
The case where I see people run into trouble here is in the spouse/partner case. Someone gets married and then tries to sponsor their spouse. The visa office notices they lived together for a year before the sponsor became a PR and reviews the original PR's application and sees that the partner was not declared. While some think this is deliberate (and I know there are cases like that) I think it is also cultural. The applications are evaluated according to
Canadian law, while many people think living together before marriage "doesn't count".
I've also seen cases where a visa office refuses to examine someone and later they are sponsored.
In reviewing case law, I've seen
one case of an undeclared child being allowed for sponsorship. In that case, the father did not even know of the child's existence at the time he immigrated and did not declare him. He was refused, but the court overturned the refusal.
It's always best to have a child examined, even if there are no plans for the child to come to Canada. Sometimes the other (custodial) parent will refuse. In such a case, I always wonder why the custodial parent is punishing the child - because it is the unexamined child that is the only one who loses in that situation. An examined child, for example, could choose to come to Canada for college - it's significantly less expensive. But a refusal to examine forecloses that option.
i went back my previous posts and Leon answered my question with this link. Hope this helps.
