Hi, I have a friend who is facing a serious problem. I am helping her as I'm a paralegal who works in litigation / family law matters. But I don't have extensive experience in immigration law. My friend is a Mexican Citizen who was successfully sponsored by her Canadian husband and received her permanent residence last year. She and her husband have now been facing difficulties in their marriage due to alcoholism, financial issues, etc. I am helping her apply for her divorce through the courts. My concern, though, is something that her husband recently brought up to her in the process of her asking for a divorce. He mentioned to her that he had a marriage which he had annulled and which he didn't claim to IRCC at the time he sponsored her (the details of whether that marriage was actually properly annulled are suspect). So now she is worried that because she wants to divorce him, he could go back to IRCC, tell them he lied about his marriage history, and claim that they weren't legally married at the time of her sponsorship. What would happen in a case like this? She didn't lie on her application but he as the sponsor, it appears, may have. I hope she won't face problems with her PR because of this...
