Calgary to Grande Prairie
One road that most people don't take is the Spray Lakes road. Take the exit off the Trans Can 2mi east of Seebe to highway 40 south toward Kananaskis. Then exit to the west (right) and follow the road toward Spray Lakes Road. This route will take you into Canmore through spectacular scenery, lots of wildlife, and less traffic. I was last there in January 2008, windchill -75C...riding in a Jeep. Canmore can be a bit of a pain, given the crowds, but Banff is worse.
