Several points:
- Tesla never gives out information on Supercharger build out - the only info is on their Supercharger map - Coming Soon, Coming in 2018 etc
- Permiting for Superchargers is generally a local matter. I wouldn't expect the govt of Ontario to have anything to do with it or any knowledge of it, unless Ontario is different from most places in Canada and the US
- The perception is that Tesla has throttled back the Supercharger build out to help achieve profitability
- Superchargers may be under construction and we won't know unless someone spots them - unlikely in remote areas. Superchargers even in densely populated areas have appeared already built and ready to go without anyone here or on Supercharge.info knowing in advance.
- All this may change if Tesla really does go private. Funds may open up.
