I'm not sure it's a question of resources as much as it is a question of reliable and accurate data, which I'm not sure exists anywhere. It involves offshore financial centres, which by definition are not very co-operative when it comes to revealing the dealings that their institutions have with Canadian corporations or Canadian residents. I think it's a matter of trying to get the appropriate data. A parallel that I sometimes make is trying to estimate the amounts that the Mafia makes. It's very difficult. You can try to estimate but you cannot get reliable estimates.
