There's a UU Fellowship in Bellingham, which is pretty active. A bit of a hike from Vancouver, though.
There are also UU churches in Nanaimo, West Vancouver, and Victoria (ok, that one is too far away)
I've seen that on the web site!
Even the West Vancouver one is pretty far. About 10 k in direct line, more than an hour's drive (it's across the water from me!). I'm surprised they don't have a group in Vancouver...
