Actually, I think you made two points that I'd like to respond to.
The first is on the health care. As we do the broader analysis on fiscal sustainability, building on the work we did in 2010, we do, as in all of our work--to respond to Mr. Wallace--actually look at sensitivity. We'll show you different numbers. We have different scenarios for health care. If there are things going on in the development that we're hearing out of federal-provincial discussions, we could build some richer scenarios for you. We'd be happy to do that on health care. We could build that into these fiscal projections.
Just on the fiscal cost point of view, I think the Department of Finance does cost changes, up or down--personal income taxes, corporate income taxes. We do get information. We do model it. We don't get a detailed corporate income tax model. We do our own rough estimates using private sector models.
It is possible to say. We need to know, for fiscal due diligence purposes, what a 1% or 2% cut in corporate income tax will mean fiscally. There is a cost to it, notwithstanding that one of the economists you alluded to.... Even the Department of Finance assumes that if we reduce corporate income taxes, there will be a fiscal cost.
