It occurs to me that it probably costs a lot for Hydro to install the transformer, run the 1Mw feed, etc. That money plus probably some monthly electricity minimum charge becomes due I assume when the equipment is hooked up. Plus, there'd be a peak power rate to pay for a small number of visitors at a very isolated charger. A single supercharger too far from others is not going to be very useful. So most likely Tesla's strategy is to do all the ground prep first - fairly cheap, it seemed to be 3 or 4 guys and a small backhoe. Then, when all the sites are ready, do a blitz to install equipment all the way along the Trans-Canada in one swell foop, opening up the route and "open the floodgates" of traffic.
