Those are astounding amounts.
Next, in your conclusion you say that if we assume that 10% of the trillion dollars in reportable transactions has avoided corporate income tax in Canada, it would represent an amount of $100 billion in taxable income that should have been taxed. Then you make an estimate of the billions of dollars that is part of this massive tax chasm that exists.
The assumption of 10% comes from where? Is it possible that the assumption is actually low and that, potentially, the percentage of those transactions avoiding corporate income taxes in Canada is much higher than 10%?
