Thank you.
The other question, Minister, is in relation to closing tax leapholes—loopholes. Well, people leap through them, I think.
International tax evasion and aggressive tax avoidance have a terrific fiscal cost to governments and taxpayers. They undermine the revenue base and undermine public confidence in the tax system and in the fairness and equity of the tax system, quite frankly. In economic action plan 2013, we've strengthened the integrity of Canada's tax system, I think, by going after these loopholes that people are leaping through. Do we have some specific numbers on the amount of dollars that are out there? I know it's very hard to estimate, but we must have some numbers on the amount that we stand to collect by closing these loopholes.
