I have Canadian citizenship and my husband has permanent residency. During the 4 years we were outside Canada, we were studying some courses in the English language and other things in Canadian universities (online) and we were receiving student aid (OSAP) (without knowing that this is only for those actually residing in Canada). Now my husband received a letter asking him to provide proof of our children’s expenses, housing rent and many details. Of course, we do not have any of these papers because we have not entered Canada for 4 years (do you have a solution to this problem)?
