I'm all for a local pollution tax (if you're dumping crap in our local waters, you should pay a bunch of tax to the region) but carbon tax should be a global thing, otherwise it puts Ontario manufacturers at yet another disadvantage against international counterparts.
If you want to save the world, then it would be better to give massive tax breaks to green innovators that set up and employ people here. You'd be helping people get good jobs, and saving the planet at the same time.
