Yes. It is becoming more and more of an issue. We eliminate some every year, but I do not underestimate the skill of people who work on Bay Street—as Mr. Brison used to—in finding ways around the rules.
We work at it. The people and my officials are here, if you want to get into specific tax loopholes. Some of them are very complex. They all have esoteric names, so one is not really supposed to know what's going on. We have various tax havens around the world. The OECD took a leading role on this at the G-7 meeting we just had in the U.K. The ministers, all of us, had a detailed discussion about doing more together on tax loopholes.
One of the challenges we have, of course, is arbitrage, that companies are free to move around the world in terms of where they choose to pay tax, or they pay some here and some there, and so on. We need to coordinate our efforts internationally.
