I loved your Trip report! Looks like you had a great time.
As you can tell by my Screen name I spent a lot of time in YYC(Calgary). I left Calgary in 2008 to try my luck in Atlantic Canada and I haven't been back to Calgary since. Seeing your pictures of Deerfoot Trail and the Trans Canada highway approaching Kananaskis made me a little homesick.

-25c for a daytime high? wow, you went to Calgary on one of our warmer days, hee hee.
Curious, why Calgary? You were doing Disney and Vancouver but what made you put Calgary into the mix?
