Going from 15% to 15.5% is an increase in tax, not a decrease in tax for the lowest income tax bracket. I will not argue with you. You can go to the CRA website. I went to the CRA website three weeks ago to do some analysis.
For the poor or anybody, go to the 2005 tax return and to the 2006 tax return. There is an increase, but because it was for half a year the increase turned out to be 15.25%.
