Nothing comes immediately to mind in terms of putting a dollar figure on the cost of child poverty. There's been a lot of work in terms of some of the social and emotional outcomes for children living in low-income families. But we can certainly look into that.
As Garnett pointed out, it is important in terms of the intergenerational transmission of low income. Adult children who were raised in low-income families tend to do pretty well. I don't know how good a proxy that is, but it is worth noting that Canada does well internationally on that front.
