Sorry, but this tax is a boondoggle and way for government to collect more money from taxpayers.  As for the necessity of curbing carbon emissions, well if you completely support all the climate science, Canada's numbers in this area are so miniscule as to make this big expensive effort almost ridiculous (except for the boondoggle of course).  

 If there's an international accord and I see the real carbon emission culprits (based on the projections of the climate change model) paying their proportionate share (i.e. China and India), I might feel differently about this.  But in a country like Canada, which has minimal emissions and is made viable only by the fuel that heats our homes, the sound and fury over this issues is laughable.  

By all means let's look for better sources of energy - but not at the expense of  taxing Canadians' ability to survive here.
