OTTAWA - An abridged timeline of carbon pricing developments in Canada:

— Nov. 19, 2008: Conservative speech from the throne promises, "We will work with the provincial governments and our partners to develop and implement a North America-wide cap-and-trade system for greenhouse gases and an effective international protocol for the post-2012 period."

— June 10, 2009: Conservative environment minister Jim Prentice releases two draft documents he says "lay the foundation for the development of a carbon market across Canada .... It does so by establishing a price for carbon in Canada — something that has never been done before in this country."

— December 2009: Conservative government says it is "working in collaboration with the provinces and territories to develop a cap-and-trade system that will ultimately be aligned with the emerging cap and trade program in the United States."

— Nov. 12, 2013: Prime Minister Stephen Harper's parliamentary secretary issues a public statement: "Canada applauds the decision by Prime Minister Abbott to introduce legislation to repeal Australia's carbon tax. The Australian prime minister's decision will be noticed around the world and sends an important message."

— April 7, 2015: Release of "Turning the Corner: A Practical Approach to Reducing Canada's Greenhouse Gas Emissions," by Canada's Ecofiscal Commission, recommending provinces take lead on carbon pricing.
