Certainly. In general, what we see is that income splitting or pension income splitting, which has been implemented now, benefits higher income individuals more than lower income individuals. Part of this is because if seniors are unattached, they don't benefit. Thirty per cent of seniors are unattached. Seniors who are unattached are more likely to live in poverty. They're more vulnerable. The less tax you pay, the less you benefit from this type of tax incentive or tax expenditure.
The more income you make, the more you're going to benefit from this, particularly if there is a higher income spouse and a lower income spouse. They'll benefit more in that situation. What we say is if you look at this from a perspective of gender analysis or inequality analysis, you'll see that the tax expenditure would be far better spent improving GIS and keeping OAS at 65, for those who need to retire at 65. Not everybody can work past 65, and in fact, Canadians who can work are continuing to do so. With the financial crisis, their pensions have been decimated, so they're continuing to work.
