Im a Jamaican and my wife wants to have the baby in canada, i will pay but how much will it cost?

I will assume your wife is also Jamaican? You will both need to enter the country with holiday visa's--unless you are forgetting to tell us something. If your wife is expecting -- you will need medicals --her doctor will have to permit her to leave your country and enter Canada--this will not happen if she is expecting. Canada will also not permit her into the country--you can not just go into another country to have a child to obtain entry into that country. Your child --if born in Canada--will not be automatically a Canadian citizen--so the chances of you having the child in Canada look pretty slim.
