Right. Southern (and to a degree, central) B.C. is much, much milder than the Canadian prairies. Warm enough for grapes, cherries, apples ... major orchard and wine country. People often retire to Victoria (on Vancouver Island) when they get tired of fighting the cold Prairie winters.

In the northern parts of B.C., I don't know. That's boreal forest country, and I suspect it's similar to southern Yukon (say Whitehorse), which is about the same temperature-wise as Edmonton up to Christmas, perhaps, and then ... wow ... the bottom drops out of the thermometer. Seems like the moderating influence of the Pacific air masses, systems out of the Gulf of Alaska, give way to those collossal high pressure systems from the high arctic.

(Fine folks in Yukon, though; I want to go back there. Always up for another pint or two at The Pit in Dawson City. My uncle runs a trapline up thereabouts; could be an educational winter.)
