The important thing about this document is that beginning in 1995 a federal-provincial-territorial committee led by Status of Women Canada calculated each of these different gender gap measurements.
Page 3 lists the measures that were developed for incomes. If you look on the left-hand side of page 3, you will see that this index has already been calculated for 1986, 1991, 1994, and 1997. For purposes of monitoring the work that comes out of the Department of Finance, including the $100 versus $1,000 type of analysis, these three measures--the total income, the income after tax, and the total earnings indexes--are the specific tools that have already been in use in Canada for over a decade. They haven't been updated recently, but these are the tools that will show what happens if you do that.
If you have a proportionately greater reduction, you should be happy because you have a proportionately greater reduction, right? These tools will show how, on a macroeconomic level, that's not working. These are the tools that have already been road-tested and put into place here.
