Mr. Speaker, climate change policy should tangibly reduce greenhouse gas emissions without punishing the Canadian economy. The problem with the Liberals' approach is that we know they have no evidence to show it is actually going to work, that it is actually going to reduce greenhouse gas emissions. However, we do know that it is going to cost the Canadian economy and cost Canadian families.
Under our former government, we actually saw greenhouse gas emissions decrease, while the economy grew. I have a very simple question. What price elasticity assumptions did the government use in modelling its carbon tax?
