Plant Galls of Illinois
which is admittedly pretty far from BC, shows a similar Willow Cabbage Gall caused by a gall midge Rhabdophaga brassicoides, for whatever that is worth.

Rabdophaga salicisbrassicoides
Ron Russo's book Plant Galls of CA and other Western States shows a willow bud gall like this as Rabdophaga salicisbrassicoides. I think it's probably the same gall you found in the Illinois book. Nearctica lists R. salicisbrassicoides but not R. brassicoides, so probably the name you found changed at some point.

BC is closer to the western US than Illinois at least.

Just for the matter of thoroughness... Nearctica lists nine R. salicis* species, which sounds as if there are at least nine Rabdophaga species that occur on willows. Russo's book describes four of them. Only one matches this photo. Don't know what the other five look like or where they occur.

I have photos of this gall from California -- haven't gotten around to posting it.
