I agree that the use of closed software for this is not ideal, though I
think it's far from the most worrying thing about this whole process.
Perhaps that says more about the rest of the process though... I'm glad
we're at least talking about cleaning up the data now!
If anyone is interested, I've documented some open-source code for
cleaning up building geometries for another import:
https://github.com/Nate-Wessel/hamilton-import
Some of the same PostGIS scripts could easily be reused here, especially
the simplification step, which takes account of any shared walls.

someone else replying 'I'm not installing postgesql for you to accept
simplification'? Does anyone else find it a little ironic that the
community would move forward with proprietary software over open
software?

Are you talking about the older CANVEC data or the data that Stats
has released which is really municipal data?
Thanks John

Ah, good dialog ensues. Municipality by municipality, in
conjunction with BOTH the StatsCan and Bing data, the right
things are getting noticed, the right things are getting
human-realized at what the next steps are to do. It gets better.
Yay. Stitch it together. One municipality at a time. One
province at a time. Pretty soon, after a few revisions of data
and back-and-forths between municipalities and province-wide data
checking, you've got something. There, you go.

too complex (urban cores)

Unfortunately there are over 3,000 in Canada so yes ideally each
would be treated separately in reality each municipality doesn't
have a group of skilled OSM mappers who are capable of setting up
an import plan and doing the work although there is nothing to
stop them doing so.
