No, we don't, but we know that the estimation of transactions is, as I mentioned, over $1 trillion. Given globalization, one can only expect that they will be increasing, so the amounts of tax are significant.
We do mention in the report—in 7.52—that the agency had been quite aggressive in going after some trusts. In 2005 they identified 72 trusts with capital gains of over $600 million that were created to avoid Canadian tax, and they reassessed them.
So we're easily talking about hundreds of millions of dollars.
