Yes. One of the issues in comparing tax systems, tax rates, or tax approaches is to have a common effect. The Government of Canada doesn't have a common approach to these things. Some products are taxed for excise on the basis of the amount of alcohol in them in terms of absolute alcohol, while some products are based on the amount of volume, so it's very difficult to even get a comparison, because of the different approaches.
We've been asking the Department of Finance for a number of years to at least adopt a common approach, so that when everyone looks at this, they can see what the relative tax burdens are. We've not yet been successful, but certainly one of the early steps that could be taken to help everyone understand the different levels that are being applied is to come to a common unit of measure in terms of the application of tax.
Honest to God, I think only the people in the excise division actually understand the nuances of the different approaches and how they compare with each other. It's very difficult for us to do that. We do it; certainly it would be very difficult for the ordinary layperson to do that, but unquestionably it is one of the issues that need to be addressed--so your understanding is correct.
