I'm going to answer your question briefly and then I'm going to leave.
In theory, you can say that you have to seize the property of criminals, but it's very difficult for police departments to get convictions and effective seizures. The current practice of lawyers is to negotiate criminals' property in exchange for a guilty plea.
Broadly speaking, the problem is that the trials are too long in Canada. In comparison with the United States, sentences in Canada are far too lenient, and it's too complicated to secure seizures. We have to start by seizing property here before thinking about attacking tax havens. That's definitely where you hit organized crime, but there are so many tax evasion methods that it's virtually unthinkable to achieve any major effectiveness here.
The United States had to take a number of approaches to attack Switzerland's bank secrecy which citizens enjoyed, not all of whom were members of organized crime. These citizens had a number of billions of dollars in tax havens. The solution would be to go after the money in the pockets of the criminals, and that's where you have to take innovative steps, as my colleague said earlier.
