The map on the Tesla Supercharger page has been updated an there are now grey coloured "Coming Soon" SCs. There appear to be some that we have not seen before, including Owen Sound. It also looks like they have the following locations (guesses from the map): Ft. Erie, St Catherines, Hamilton, Brantford, about three in the GTA, Belleville, Ottawa, Petawa, North Bay, Sudbury, Owen Sound, and about 11 locations in Quebec.
edit - On second thought it looks more like Owen Sound than Tobermory - post above changed to reflect this.
