My question is a little complicated because I wanted to talk about risk management. You gave an answer saying that when you're assessing risk you probably have a debtor profile or a taxpayer profile. And you go after that specific profile. You mentioned that if you live in a certain area like Rosedale and you declared a $14,000 income, you'd be in real trouble.
There's a lot of tax--I wouldn't say evasion. The tax law allows people to take certain credits, for example, the MURBs. They are those tax shelters they have.
When does Revenue Canada decide whether that shelter is not good or bad? When does it change its legislation? When does it change its treatment? How much notice does it give to these individuals? These individuals turn out to be our constituents, who are a little concerned at the unfair treatment they are getting by sudden changes in legislation without their knowing about it.
