Don't carbon taxes affect low income earners the most?

Although a flat tax on fossil fuels would seem to make the tax system more regressive, high income Canadians use more energy than low income earners, and would therefore pay more tax.

Many low-income Canadians will require financial assistance to deal with additional costs that they can't avoid - those living in apartment buildings who have no control over heating costs, for example. Providing support for those who face costs that are unavoidable in the short term is a critical component of an acceptable carbon tax policy.
