CanVec was what I aligned to. That and local knowledge - I know parts of UBC

If the Vancouver license isn't compatible with OSM the wiki should be edited
- it says it's acceptable as is.

were still waiting for OpenStreetMap to change it's licence :) lol...
but anyway, geocommons.com is a good temporary home for the p files :) and
having the data on standby just waiting to use used is helpfull.
