Yes, I expect as EV's become more common, so will charging. As I understand, other than Tesla, every EV sold from now on will be CCS (Chademo obsolete here? Only for existing cars?) There are plenty of places that are too far off the beaten path to expect Tesla to cover - some of the more rural areas of western Canada, for example. But if the demand is there, there will be CCS chargers. (For example, Jasper to Canmore Ice Fields Parkway, with frequent stops, currently looks to be an iffy drive, assuming a SC eventually shows up in Jasper. But if everyone wants to drive it, there will be a CCS in Lake Louise, and maybe at that halfway point or some park stops eventually. Even if it's a way to go from say, 20% to 50% to make me more confident of the drive, it would help. Ditto going south route in BC and then going down into the USA.
Plus, Biden is promising thousands of chargers across America. Those will obviously be CCS. At that point, CCS adapters solves Tesla's "lineups at chargers on holidays" problem.
