Madam Speaker, I thank my colleague for her question and her advocacy on this issue.
However, I would like to remind her that we were not in government 10 years ago. The carbon pricing system that was proposed at the time was the Harper government's, not ours. That government was in favour of imposing a carbon tax one day, against it the next, and then in favour of it again the day after that. The Conservatives are still doing the same thing today.
I would also like to remind my colleague that institutions such as the International Energy Agency and the International Monetary Fund have said that our carbon pricing system is a leading model for fighting climate change. According to these institutions, if only two-thirds of the countries in the world adopted the Canadian carbon pricing system, then every country on the planet would have already met the Paris targets.
