he did not declare his wife and daughter when he landed as a PR in Canada that the problem if have idea tell me pls i need to know at soon as possible
A person applying for a PR visa has to declare his spouse and children on the application. He has to declare them when he lands in Canada. If he didn't, he can not sponsor them later.
CIC takes this very seriously. Why didn't he mention them on his application in the first place? And why didn't he declare them when he landed? (It doesn't really matter what reason he had, though; they cannot be sponsored by him.)
