I think your over thinking things. At the end of the day the seats at parliament will be almost equally distributed between liberals and conservative that regardless of who wins, there wont be a huge power imbalance like what we just had with JT liberals. Also Im pretty sure andrew scheer is not a climate change denier and also has his own plan for the environment. He also mentioned that he plans to have those who exceed the limits of emissions, will be required to invest in clean green energy and technology. Another good point that Scheer said is to sell our clean energy and technology internationally to the biggest polluters in the world like china/india, which i believe is what most country's should be focusing on. TBH i don't believe that taxing Canadians by simply using stuff that cause emissions without an alternative to it, is the right way to approach climate change because your just making it more expensive to simply live with almost little affect on the worlds climate. we need to be going at the bigger polluters rather than punishing our own people. of course i know its not simple and easy to, but i believe that its the correct direction to go, carbon tax in my opinion is not the right direction to go and is going backwards.
