I guess that falls to me.
Clearly we're in a competition for capital around the world. We're trying to attract head offices, and we're trying to attain investment within Canada. It's really important that we try to create the most competitive tax regime possible within the country. The unfortunate reality—and I said this to a crowd in Calgary yesterday—is that we're actually forecasting that private investment will contract marginally this year, because even though nominal investment is growing, with the dollar going down 10%, we're actually seeing the cost of importing new technology, for example, falling. It's hard to find the hard evidence right now that a lower corporate tax rate is actually converting into stronger investment. The trouble with that is we don't have a counterfactual. The world could have been even worse off. Looking at the entire suite of policies over the last number of years, I think a variety of things have been done by the federal government and by provincial governments to create a more competitive tax regime, and corporate taxes are part of that.
