I can tell you that a number of measures can indeed be put in place to mitigate the impact of the carbon tax on low-income people. First of all, we have to understand that the most disadvantaged people use very little energy. Low-income people have no vehicles, for example, and that is true all over Canada.
Involvement is certainly needed in the area of housing. Targeted energy efficiency programs can be established. In other cases, some countries have chosen to provide energy rebates, and they literally put money back into the pockets of low-income people. So a number of mechanisms have been used by other governments, here in Canada and elsewhere, to mitigate the impact on the most disadvantaged.
Clearly, in the medium term, the impact of costs often improves when you succeed in moving from expensive energy to energy that is less expensive, for example, or in insulating houses. However, at the end of the day, we are recording clear savings, which probably explains the figures that Mr. Leach provided.
