OMG that is so incredibly off base and myopic. 
The issue here is that this isn't really about global climate change at all. In fact - true climate change activists should feel disgusted and used like a cheap hooker on this one. 
Its a pure tax grab, wrapped up in the most crass and userous manner in a do good climate change concept. (note - not a plan - they don't have a climate plan - just a plan to take whats left in your wallet) 
Think  - Think globally - Ontario already is a relatively clean jurisdiction. if we drive out manufacturing, where do you suppose they will go? Germany? Sweden? Away?  No, they are going to Mexico, China, Taiwan, Philippines, Etc. All massive carbon producers. Even the US is dirtier than we are and guess where their pollution ends up - here. 
So now what have we really done - lost our economic base - AND INCREASED GLOBAL CARBON PRODUCTION in the process. 
Think, think, think beyond the bumper stickers and populist causes of the day.
