Why don't you address the issues that 1) Ontario is not reducing GHG emissions, it is simply exporting them to the US to release, 2) good high-skilled, high-paying jobs are being destroyed in Ontario and Illinois is happy to take those jobs, 3) China and India are not only producing more GHG than Canada, but their annual output has increased more than Canada's total output, 4) if Canada doesn't export oil to Asia, the Arab countries will with no net change in GHG, and 5) Canada's output is insignificant, at just 1.6% of world output and falling.
I am not suggesting that Canada do nothing, but it has to be sustainable for Canada and Canadian jobs, it has to do more then simply shit GHG emissions to other countries, i.e. actually cut emissions and it should not be subsidising foreign manufacturing .
