Nope - no way. Because you
deliberately kept your wife and son a secret when you landed, they are excluded from the family class and any application you file to sponsor them to Canada will be refused under Section 117(9)(d) of the
IRPA Regulations. This part of the Act is there in the first place to prevent people from hiding family members that they feel will cause their application to be refused - and people do this knowing that a medical or criminal issue with a spouse or dependent will make them inadmissible to Canada also. Sadly, if there weren't any medical or criminal issues with your wife or child, adding them to your application as required would
not have caused your application to be refused. Now you've no way to bring them to Canada unless your wife can qualify on her own as an Independent Immigrant and, frankly, it really frustrates me that people allow themselves to be so completely uninformed about the consequences of such a decision before they make it - but, you were blatantly dishonest and, for the record, you misrepresented yourself and that puts your own PR in jeopardy.
