Activists don't like Trudeau's middle of the road approach, since, by his governments own admission, carbon pricing would need to be an economically crippling 2-3 times higher than the current plan to move the needle on Canadas 1.6% contribution to global GHG emissions.  And most conservatives would rather scrap the tax entirely.  So overall,  Trudeau's carbon policy is window dressing that will drag on the economy while yielding limited environmental benefits.  This after Ontario's green jobs fantasy has already been dispelled.   Despite the high likelihood of failure to realize benefits, it's still a tax, so it's hard for the Liberals not to get excited about it.
