a friend of mine applied under spousal sponsorship. The only thing that he is worried about are some under the table jobs he did in Canada and he did not report them in the Spousal application. He did not even mention about it to his lawyer. Would it be possible for Immigration to find out? He had reported them to his former caseworker as income before but canada revenue has no records of them..Would he be considered misrepresenting facts under spousal sponsorship?
