Your most likely going to be leaving the TC-1 at Lake Louise and head on up to Jasper and North from there. Your good to go, all good road and places to stop. However you can't boondock in any National Park or Provincial park.
Myself I don't travel on the TC-1 west from Lake Louise because of traffic. The section of Hwy TC-1 west from Lake Louise to Salmon Arm is mostly a two lane road with a huge amount of truck traffic heading west and east through out Canada. It is the main truck route between Calgary and Vancouver and is also the main route that a lot of people use as well for accessing BC.
It is a good road , just a LOT of traffic that gets bottles up on the two lane sections, and that's where you see people making stupid moves.
