Mr. Chair, I think the member opposite is confusing a number of issues, but the offshore tax gap generally refers to federal income taxes that are not collected because of the under-reporting of foreign source investment income by Canadian individuals. By its very nature, international tax evasion is difficult to quantify since it involves people or entities deliberately and aggressively hiding money from the authorities. Estimating income from deliberately hidden or secret offshore investments is extremely difficult. Apparently, the member opposite has information that most of us do not have.
