Hey Bjenk, On the Address data, the Talk-CA group has had several discussions about it. The problem boils down to Canada Post, which treats the information as proprietary - they provide any individual going to their site the right to lookup an address in order to utilize their service to mail items. The actual database is theirs and even the postal code on my home is theirs, I'm just allowed to use it. This all likely has more to do with the fact that they have a service that links the addresses to mapped locations that is, of course, available only for those willing to pay for it. If they allowed OSM to integrate this information, they would lose that revenue stream.
Suffice it to say that, apart from an individual adding their address manually to the map, Canada Post is not about to allow any party to use that information freely.
