If the system can be "gotten around" the problem is with the system, not so much the people trying to "get around" it. Either an action is illegal or its not. For example, if Parliament doesn't like people leaving Canada after applying for citizenship, pass a law forbidding it. Don't subject otherwise sound applications to delay and suspicion because you don't like someone's otherwise legal behaviour.
This is the problem with what is going with this government right now. They don't change the law, but they come up with all kinds of other bureaucratic ways of effectively creating new law without going through Parliament. They moan about creating a longer residency requirement, but in reality that residency requirement is sort of already in place. People are afraid to travel after submitting their applications, effectively making the residency requirement about six years as it is now for many people. Of course, a lot of weddings, funerals, and much needed vacations in the sun are being missed by people afraid to engage in otherwise perfectly legal activities lest they be subjected to the bureaucratic slow walk through the Black Hole of an RQ.
Of course, there is nothing statutorily illegal about CIC's slow walk either, but there are certain principles of fairness and reasonableness in the performance of public duties that the current backlog and waiting times clearly violate. Why in the world there isn't a class action law suit on this in order to establish some legal benchmarks of fairness in the process is beyond me. We clearly aren't going to get this from the political system.
