Tesla shows Fernie, Creston, Grand Forks, Castlegar, Osoyoos, Princeton on hwy 3 ... but NOT Cranbrook!
Putting one in Cranbrook would mean only 100km between each supercharger from Fernie to Creston without much of any dramatic elevation changes across the Rocky Mountain trench. After Creston heading West, there are considerable mountain passes to climb over.
Where I see a hole would be in Invermere (or maybe Radium) to link to the Golden superchargers going up hwy 95 (123km), or the Canmore supercharger via Kootenay Park (173km). The lake Invermere area is a common destination for those with 2nd (or 3rd

homes from Calgary. Calgary to Invermere is 275km. Fernie to Invermere is 211km, Creston to Invermere is 239km. So Invermere would make sense as a midway point between Fernie, Creston, Golden, and Canmore Superchargers.
Then there is the missing link between the Missoula MT Supercharger and Golden/Canmore. I think there might be a plan for one in Kalispell (335km to Invermere. 516km Missoula to Invermere). In this instance as well as for hwy 3 generally, it might make more sense to have one in Jaffray near the junction of hwy3 and 93/95 instead of in Fernie. There is already a BChydro ccs/chademo Flo charger there, and Fernie is more of a weekend destination for Albertan's with several level 2 chargers already there. Missoula to Jaffray is 355km with Kalispell halfway in between, and Jaffray to Invermere is 162km. Fort Macleod Supercharger to Jaffray is 210km, and Jaffray to Creston is 152km.
