I might add that Canada doesn't have the muscle of the United States to have as effective a deterrent. We're a small country. They're a large country; they have much greater resources.
UBS, for example, had 28,000 employees--more employees in the United States than they had in Switzerland. In the rest of the Americas, there were about 1,100 employees. UBS assets here, in terms of its branch operation and its subsidiary, were in the nature of about $2 billion, which is a grain of sand.
Even in the United States, it was not possible for the IRS to bring UBS down after Lehman Brothers collapsed, because the world financial system would have collapsed.
This problem is international in scope. Canada has limited resources to deal with it.
