We have micro-simulation models, but tax policy is the responsibility of the Department of Finance. We model the impact of various tax measures.
In my presentation I talked about the broad range of measures that the government is taking. I highlighted two specific ones. One is the child tax benefit supplement, and you pointed out that the change at this time is with the income threshold, whereas the working income tax benefit is literally a doubling in terms of the dollar amount. I think the advantage of the working income tax benefit is that it permits the provinces to adjust it so that the income security benefits they are providing their residents aren't adversely impacted by the design.
