This subsidizing of oil and gas by governments in Canada is more a figment of the imagination of the preacher at the holy church of the environment. As of yet electricity doesn't have any tax collected to cover the cost of the infrastructure that the electric cars will run on - if you want to make a deal of taxes
 I believe that the Ontario government subsidy is $14,000.00 plus they are going to be building charging stations all across the country using tax dollars. On a cold winter night with a layer of wet snow on the highway driving into a head wind, electric cars with moderately old batteries are going to need these charging stations big time.
