text: GST is applied on top of the "carbon tax" (which isn't applied on carbon leakage from hydro dams etc. only fossil fuels) so this is a huge windfall for the federal government"s coffers.  "all carbon tax money stays in the province it was raised" is not true unless Ottawa also sends the extra GST back to the provinces too.
  
  Also, the cap and trade is a floating market mechanism so making sure that each year is a certain price per ton is nearly impossible...this could be a big warm on national unity if the cap and trade provinces don't have the same price as the carbon tax province every year.
