The Climate Change Plan for Canada provides estimates of price increases in various commodities. These figures are based on the economic scenario that the federal-provincial analysis and modelling group agreed to more than a year ago, and the assumptions of the international price of carbon permits of $10 or $50, and assumptions of domestic market dynamics based on extensive discussions with and advice from key industry sectors. Actual price increase for various commodities could differ significantly using alternative approaches to mitigation.
