We've done a lot of work on the impact of various tax cuts. As for personal income tax, yes, the federal government might get about 20% of its money back over time, because of the expansion. For corporate income tax, yes, there have been a lot of studies; it really does stimulate investment. In fact, regarding the impact of the harmonization itself with the three eastern provinces, a recent study showed it was very effective in increasing business investment in those provinces.
Some people think, why doesn't the government cut taxes, because it can get its money back? Let's not go that far. We're talking about 20%.
