Current Ontario electricity rates range from about 14.7 cents/kWh off-peak to 21.7 cents/kWh on-peak, so the prices you quote are actually $8.82 to $13.02 for a full 60kWh charge, maybe a couple dollars more when you factor in efficiency losses in charging.

Remember you pay for delivery, regulatory fees and taxes in addition to the straight-up electricity rate.

Still a cheaper energy source than a comparable gas powered car, particularly for high-performance vehicles, but it will take a lot of driving to make up for the higher up-front cost.  A Chevy Bolt, for example, will set you back almost $20,000 more than a similar sized and equipped Chevy Sonic (before subsidies), so even if all charging is done off-peak you're still looking at 275,000km+ before the cheaper fuel cost offsets the higher upfront cost.

The economics of electrics make a lot more sense when comparing a Tesla Model S vs. a BMW 7-series or some such, but most of us can't afford either a Model S or a 7-series.
