Let me open parenthetically regarding my earlier answer. I should have known the answer by heart. The child disability benefit remains up to a maximum of $2,730. That's the precise number, which I didn't remember by heart. The answer was faster than I thought it would be.
Now regarding income splitting, there are three reasons that militate against income-splitting measures. The first reason is simplicity. We're assisting families with the Canada child benefit in a very simple manner: it's a single non-taxable transfer every month. A family's transparency and simplicity is greatly enhanced through this particular measure. The second reason—and I think we all agree on this—is that it's those families that need it most that should receive support from the Canadian government. Our resources, as I said earlier, are always going to be limited. We need to invest in those families that need our support most, and income splitting doesn't do that. The third reason is that we are in a modern economy in which the two spouses often work. Incoming splitting will impose on the spouse with a lower income the same marginal tax rate faced by the spouse with the higher income. Nowadays the spouse with the lowest income generally is the woman. Income splitting discourages labour force participation on the part of those lower income spouses. It's the women that typically are lower paid. Since income splitting imposes the same marginal tax rate on the same people in the couple, we think that's not the way the tax system should operate.
