I currently live on Salt Spring, so I can't speak to what's available in Vancouver right now, but I just signed up for a CSA myself and its the only thing I've done that has provided any real feelings of having actually done something smart and productive in the face of the American threat. I just wanted to say that I think it's great you're doing so, and I hope more people consider it! I know the upfront cost is off-putting and for some it's insurmountable, but if you can, it's a great choice!
