I can start, and Shawn can add.
The market basket measures have five components. The food basket was based on the office of the nutrition policy from Health Canada from 1998. We're expecting to update that based on the 2008 food basket, so that it will reflect the nutrition guidelines as of today.
There's a transportation component. For the element for transportation in rural areas, where it's necessary to have a car in order to get around, the standard in the original estimate was a five-year-old Cavalier, a GM product that is no longer in production. We're working with our colleagues at Statistics Canada to see what would be a more appropriate vehicle.
We're also looking at shelter cost, which is a housing component. As colleagues have described, the issue is with respect to home owners without mortgages, who don't have the same out-of-pocket expenses as those who have them. We're looking at how to adjust for that, as well as for the many low-income individuals who benefit from rent-geared-to-income supplements. We want to reflect that too in assessing their disposable income.
Those are some of the characteristics we're looking at with respect to improving the elements in the basket.
