Wow, that's a fantastic question! And you're thinking in the right direction! Basically anyone living in a "continental" region in this country, that is away from a large body of water, will see more extreme daily temperature ranges or swings than someone living by the moderating influence of water.
I do believe however that Southern Alberta - namely around Pincher Creek - see's even greater swings than the Chilcotin region of BC because of the occasional warm Chinook Winds that blow through that particular area. This "exagerates" the potential for an already wildly swinging temperature regime. For example in Pincher Creek, the temperature rose by 41°C (from -19°C to 22°C) in one hour in 1962 when a particularly strong Chinook blew through.
