Okay. I want to put that into perspective.
Not to minimize this, but I did some quick calculations. I come up with about 1.5% to 2% of our budget. To draw a comparison, we lose about that amount to our tobacco industry, which I'm not suggesting is where we should be gaining revenue, but we have taxed our tobacco so high that it is now more lucrative to sell tobacco than it is marijuana.
The reason I'm going in that direction, Mr. Cockfield, is that I think I heard you mention something. Maybe you can just give me a brief answer on this. How does this compare, this $5.3 billion to $7.8 billion, to tax cheats such as roofers who don't pay their GST? Just briefly, do we have any estimates on that?
