One other thing to think about while others are discussing the licensing topic:  What is the quality of the buildings?  Has that been reviewed?

 * Are they in the right place?
 * Are they the right size?
 * Are they squared off (rectangles)
 * Are they aligned to each other and the road (not slightly mis-aligned)
 * Are they current (not buildings which have been torn down or
   otherwise changed)
 * If there are attributes like "height" in your dataset, is that
 * etc...

I've not worked much on buildings, but probably others could add comments about what are the criteria for "good buildings".

Good morning,

The Region of Durham has recently purchased Building Footprints data for the entire Region, and it is available as Open Data:

We would like to import these to Open Street Map to engage the community and help improve the overall map. We are supporters of OSM and wish to regularly partner in improving the data.

In particular, we are hosting a mapathon on March 29, which asks for student input to add attributes to the buildings based on OSM guidelines for the Building Canada 2020 project:

We have read your Import guidelines and are here to express our interest in contributing our building data. The intention is not to overwrite those buildings that the community has built, but bridge the gap to include the rest of the 200,000+ buildings in Durham (largely residential), which are missing from OSM.

Please let us know how we can contribute this valuable data on behalf of the community.
