Okay. I have just one very quick point.
I agree with Kevin's comments about selected, targeted tax credits, but there are some tax credits that are very important, and in fact aren't wrong to do, in my view. One of them is the GST tax credit. The whole concept of that was to make the GST progressive so that low-income people wouldn't pay as much. So I think there's a good argument for that credit, and I don't think one should detract from it.
On the other hand, when you get into various targeted credits.... For example, Quebec had a special tax holiday for high-tech companies in two Internet towers in Montreal. That created very significant distortions, but it was ultimately eroded by high rental prices charged for the two Internet towers. So that kind of very targeted thing often doesn't accomplish what you're really hoping to achieve.
