Maybe I can take this, Mr. Chair.
It is probably possible for us to have an assessment of the tax paid by these subsectors.
Your question about the relationship between.... I think you mentioned the total tax deduction compared with what they paid. I don't think we can really do that. There are limitations to being able to do that. The tax system is based on self-assessment.
Corporations do report their net taxable income. They also report some fields that are required to reconcile book income to taxable income, for instance, but they're not obligated to report all items and, in their financial statements, if you will, what led to taxable income. There are some limitations there.
