Perhaps think globally or regionally. In Ohio, which is closer to Ontario than most provinces, they still produce most of their electricity through coal fired plants.  (Other than the power that Ontario pays to give them.....)

Also, at this moment, the electrical charges are free of road taxes etc. that forms a huge part of the pump price per litre.  If/ when those are equally applied to electrical vehicles, what would the savings be?  Cost comparison should be apples to apples or fuel at $.60 cents per litre.
