So OpenStreetMap is CC by sa 2.0 licensed. As such, we can only use
data sources that have compatible licenses. Looking at the
contributors to the atlas:
http://www.crd.bc.ca/maps/natural/sponsors.htm , I would say that hte
data is probably not avaiable for us.

For instances, there is a great Canadian data source at
http://www.geogratis.gc.ca/ that we cannot use because although the
license is almost compatible, it has a few nasty sections, such as
termination, etc.
