I think it must also have something to do with the fact that much of the available moisture is still likely frozen not too deep into the ground, therefore the trees / shrubs are drier than they would be than their southern counterparts.
Yeah, like so much of the weather in Alberta, it seems weird to people that we have such a fire issue when there's no heat. As already covered off, it's basically a combination of the low overall humidity combined with the high winds.

I don't know that it's got much to do with moisture still being frozen, because here in southern Alberta we've already had some wildfires as well. It was really bizarre to have such a deep snowpack everywhere, which took forever to melt - and within a few days we had grass and brush fires starting. It literally goes from snowbound to soggy to bone dry in a week here. Part of that has to do with the soil too, it doesn't retain water very long.
