I created the event with
http://osmvictoriabc.eventbrite.com/

I sent a message to the local are mappers about it.
With a few responses so far. Mostly people are busy, it might also me short notice.

So it might be some remote mapping.
over on the oftc.net IRC #osm-ca might be a good place to connect & coordinate mapping activity.

There are lots of buildings that still need to be mapped.

Cheers,
Sam
