Mr. Speaker, when we were in government, working responsibly to reduce greenhouse gas emissions by regulation, protecting the environment at the same time as being conscious of protecting the economy, Environment Canada scientists and economists did cost-benefit evaluations of every piece of legislation. When we brought in legislation to reduce tailpipe emissions, which was very effective, the benefits were found to outweigh the costs, and we shared that information at committee. When we brought in legislation to phase out any new construction of coal-fired generating stations, we did a cost-benefit estimate and shared those dollar figures with the industry.
Why will the minister not share the cost-benefit studies that we know the department has done with regard to how much the carbon tax will cost the average Canadian family?
