Yes, we have, although we haven't looked at the exact numbers. When the Senate committee looked at that issue, we came to the conclusion that you needed to find a way—whether through a tax deduction or some income-tax-driven measure—that would recognize, frankly, that governments are getting an awful lot of free service, because if the family members didn't exist, a lot of these people would have to be institutionalized, which would cost the federal and provincial governments a lot of money.
To some extent, there ought to be a recognition of that, and in particular, you need an element of respite care. I'll give you an example, because I was on the phone with someone early this morning. An 84-year-old woman looking after her mentally ill 87-year-old husband desperately needs a break or she's going to crack. Yet, not only do the facilities not exist, but she couldn't afford them if she had to buy them because they're not covered under medicare.
That example, by the way, is not a random example. There are examples like that. The same thing is true for people with mentally ill children, when the wife drops out of the workforce in order to stay home to look after the child. The family income has gone down substantially, yet that's not recognized in the tax system, though it is saving the health care system a lot of money.
