Well, we have more than 180 expenditures now built into our tax code for individuals and for businesses. When we add up all the expenditures for which we're giving people credit, such as different activities, we end up losing more more than $100 billion annually in revenue. These numbers are actually calculated by Finance Canada on their website. That's the starting point for me. To ask questions about whether we're getting value for money from a $100 billion in forgone revenue....
There are some good things. I don't think anybody would argue that the RRSP has not been really fundamental to retirement savings, but I do think it's time to have a fundamental review of the working of our tax system.
Finn, you were part of the review of our business tax about 20 years ago. We got some benefit from that, but I think we have to go to the next step and ask ourselves whether we have a tax system that works for all Canadians and all Canadian businesses or whether it's too chopped up to really provide any benefit.
