C. canadensis seems possible to me, too. I have collected many of this species in my area and the appearance and size of this specimen are a good match. I find Clubiona epigynes very difficult to tell apart, though, and it is mainly because of the male and its more easily recognizable palp that I've been able to ID local females with any degree of certainty (after finding the two sexes together).

And to make matters worse, Dondale & Redner write that the distribution of the almost identical (in females) C. pacifica extends "inland to southern Alberta" -- close enough to make things much more difficult without a male.

BTW, where did you find her (habitat)?

I was sweep netting low vegetation, mostly asters, at the side of a road. This was at the beginning of a trail leading into a forest with a fast running river 100 feet away. Here's the location, but I was about 1/4 mile from the cedar swamp.
