It's better late than never to build Refineries. What if Trump puts a tax on Canadian oil crossing the border to increase the cost of Canadian Oil making it higher and less competitive just like the threatening of the Automotive industry. Trump can control Canada in that way and thats scary. If the Federal Government just sits idle like it has been it will get worse and all of Canada will suffer from the money thats being lost everyday and I do mean all including environmentalist's and green energy after all it takes money to get into green energy and thats something the country won't have in the years to follow. 

If environmentalist's want to do some good in the country quit fighting pipelines and use that energy to fight for well abandonment and reclamation. That creates work for them and oilfield workers and it's great for the environment.
