Hi all,
Canadian Geomatics posted this data set a few months back from Natural
Resource Canada.
It's Building footprints from Lidar or high res imagery.

>From what I can tell when placing the data over imagery it's very bang on.
Highly accurate, good shapes (unlike the bing files) and well placed. As
far as I can tell no one else has uploaded these to OSM. The areas in
manitoba are mainly where there's little to no other building info.
I can write an upload plan on Manitoba wiki as the data is complaint
license wise. Anything else I should be looking for? The local mappers here
are pretty excited about it.
