This is a very interesting W5 documentary which highlights a very common problem. As long as interest groups pressure the authorities for "quick" sponsorships, the problem will continue. What is needed is a change in the legislation to give sponsored spouses temporary entry only, with a probationary period of several years before permanent residency is granted upon the relationship subsisting, much like it is done in the US. If there is a marriage breakdown, there is absolutely no reason for the sponsored spouse to remain in Canada. In addition, those found to have entered into marriages of convenience for money should be subject to penalties and prosecution. Such "deals" are fraudulent and constitute a contravention of the Immigration and refugee Protection Act. What is lacking is the will and the means to prosecute fraudsters.
