I would suggest you take a look at a map of Ontario ... an electric solution may be feasible for Norway or Pennsylvania or most of southern Ontario. Not so much for Emo in NW Ontario. As with most Ontario policies, this totally ignores many of the residents of the province ... there's a whole lot of remote in this province. CAA charging stations map - enlarge so you see how few charging stations there are in Northern Ontario ...
http://www.caa.ca/evstations/ A fairer solution to all residents would be the EV incentives for southern Ontario/fuel efficient for Northern.
Distances ... Erie to Philly is a total of 420 miles; Cornwall to Kenora in Ontario is 2,027 - 2059km (1260m-1280m). The Ontario routes will not even get you charger to charger ie. Hearst to Nipigon is 402 km (250m). If I have to go see a specialist in Thunder Bay in the winter, I can't make it with an EV; even if the range was there, travel charging would be daytime rates which pushes it very close to your 40 cents/khw while adding 2.5 to 4.5 hours at best on a 4 hour trip (Atikokan to Thunder Bay is 206 km/128 m or Fort Frances to Atikokan is 151 km/94m). There is a whole lot of nothing between those chargers ... very different from Southern Ontario and Pennsylvania. By the time that changes in Northern Ontario, incentives will be gone as there is no point in buying an EV only to have it sit in the driveway. The only possible "solution" is a hybrid ... based on US MSRP Volt is $34,000 (38,400 Cdn) vs Spark non-EV $12,660 ($10,000 cdn). Even with the incentive, I would be paying double for the Volt and would still have to rely on gas. My tax dollars at work
That doesn't even take into account variances in winter temps and snow-fall. The rated 5.7L/100km on the Spark is reasonably accurate - the 2013 Spark looks to be around 5.8L/100km as half our kms are gravel road. As to reducing emissions in Ontario, we have been doing our part since 1990 with domestic fuel efficient cars (Geo, Aveo, Spark) w/o incentives way before it was fashionable...
Your 98% charge at home doesn't work in my locale ... my home to the Fort Frances charger is roughly 73km/46m. Safeway, Canadian Tire, Wal-Mart reside in Fort Frances. While I do shop in Emo (half the distance), there are numerous times those stores do not carry what I need. The 92 m round trip in the winter would likely leave me walking...
It is a cold ride for the first 15 minutes of the drive to Emo in the Spark at -50C. Walking at that temp w/o wind leaves you about 10 minutes before frostbite hits. Dressed for cold temps while snow-blowing with the Kubota (not at -50C, it warms up to snow
), I can handle the 1 hour +/- it takes but hands and feet aren't happy by the end.

Not even going to touch on heating a home with electric or geothermal lake loop ...
