That's an important question. Yes, I believe that was Professor Lahey who you heard from on that.
I think, in terms of the stock option, from the preliminary research my colleague and I are doing using the StatsCan raw data, we found that men were 6.5 times more likely to take up that option precisely because of the way in which they are situated in terms of the tax and income deciles.
I think there needs to be a general review of all tax expenditures. I know that's a thorny issue, but I think it has to be done, not just from the perspective of income deciles, but also from the perspective of men versus women. There have been a lot of very interesting studies recently that have shown, especially at the top end, what is happening in terms of tax expenditures reinforcing their economic position. There has been nothing done on men versus women, so that's what we're starting to do.
I would say it's very important for the government to be doing that because the government has the resources through Statistics Canada and through Finance to really start using a gendered lens as well as an income lens when they are making decisions about tax policy.
