Thank you, Chair.
Thank you all for being here. This is a very interesting discussion.
If I had just tuned in, I would get the impression that there is this enormous, enormous problem worldwide that corporations are cheating governments. We had a witness in last week who estimated that in Canada it's approximately $5 billion to $7 billion. Now that's a lot of money, but when we put that in perspective to our overall budget, and if we take something like tobacco sales, for instance, from which we've pretty much lost the revenue because of the high price of tobacco or the high price of taxation, it's about the same. I think tobacco sales are about $4 billion.
I want to steer this committee and I want to make sure that, as a committee as a whole, we keep this thing in perspective. Not to say that we can't and shouldn't go after tax evaders—and I think a number of you have made that very clear—but I'm wondering...
I guess I want to direct my first question to Mr. Saint-Amans. From the OECA perspective, first of all, is there an estimate worldwide of how much tax is being lost through tax evasion? Have there been studies to determine which countries are most effective? Finally, have there been studies done to see if there is a correlation between that and what happens when taxes are raised?
In this country, we've lowered our corporate tax, and I think most corporations—again, some of the testimony we've heard bears this out—understand that they need to pay taxes. Is there a correlation when nations or jurisdictions raise their taxes to a point where people start to cheat more?
First of all, to the OECA.
