The question is relevant. A few years ago I prepared a report entitled “Paradis fiscaux: l'aveuglement volontaire du ministère québécois des Finances”, [Tax havens: the willful blindness of the Quebec ministry of finance]. This report said that this expertise you are seeking is right here within the various departments of finance in Canada, at both the federal and provincial levels.
In fact, for years, the main targets of the federal and provincial departments of revenue were black market workers, servers who receive tips, provincial notaries, the small neighbourhood restaurateur; they took a close look at the black market economy, at under-the-table activities, at small sordid operations. They never or almost never found any documents—and I certainly went through all of the documentation with a fine-tooth comb—on those who own large fortunes, multinationals and the tax avoidance issue. It is but recently that we began to hear about abusive tax planning. It has only been talked about for a few years.
This documentation on the small-scale fraudster who is easy to nab and who is beset by large numbers of tax agency representatives is very present at the Department of Finance. Moreover, I refer you to this abundant documentation, as this very abundance is suspect, given the very few documents there are on the far bigger fraudsters.
