One thing that surprises me about Lake Louise is that they claim only 140" annual snowfall where as Sunshine claims 360". Does LL under report and SS over report or are these numbers pretty accurate?
Sunshine did seem to have more snow than LL by a long shot. Not sure if SS is situated better but their top elevations are not much different. Sunshine is better protected where snow comes over a ridge (upslope snow - kind of a Jay Cloud effect) compared to snow for LL comes across a valley.
