Madam Speaker, we chatted with people from the Australian government. They told us that over a two-year period, they took $16 billion of taxpayers' money out of the economy through their carbon tax, and it resulted in, oddly enough, an increase in greenhouse gas emissions in Australia, which is why they got rid of it. It was very clear that the true fact was that the carbon tax did nothing, and in fact, even with taking out a huge percentage of its GDP, greenhouse gas emissions still increased.
In the House of Commons on February 23rd, 2017. See this statement in context.
