Most of the big American shoots done in Vancouver still do their post in LA. But there's a pretty good FX community in Vancouver. Here's a few of the companies doing FX in town. (In no particular order)
Rainmaker Digital
Image Engine
Gajecki (sp?) Visual Effects
Lost Boys
Toybox Vancouver
Artifex
Check em out on the 'net. If you have a demo site, post it here.
Cheers
