Okay. I don't have any data from a Canadian perspective, but I believe, from analysis I've seen in other countries, that it is one of the fundamental issues that governments need to address because it is a significant part of the tax gap, and once it gets rampant, if people don't trust their neighbour to pay the amount of tax they should pay, then the system tends to break down.
I think it is very difficult for the tax authorities to actually combat it. A lot of it is attitudinal within society that, frankly, today just shouldn't be accepted. Work around the whistleblower. Work around more resources to enforce those particular areas. We all know there are certain areas of the economy where there are more cash transactions that happen than in other areas of the economy, so to have a laser focus on those particular areas would be another way to try to combat it.
