Thanks for the offer Daniel! However I've already processed the data through my own, similar workflow. I did a building import a couple years ago so I had everything set up on my computer already anyway. I originally tried dividing the tasks into rectangles so that they would better match a bounding-box download in JOSM. I didn't like the results so much though; if I kept the tasks around the same size (in terms of buildings), the size and shape of the tasks varied a bit too much for my comfort, with some tasks getting very large ( as in http://tasks.osmcanada.ca/project/168 ). I found that irregular task shapes didn't cause any trouble for the last import I worked on, though they did make validation a bit harder. For better or worse though, I've observed that not much task-level validation actually happens in projects like this, if all goes well and the data was good in the first place.

So, if you require the data to be pre-processed over the selected area just let me know. However, I would suggest using squares instead of various polygons to define tiles because it is simpler to manage OSM data when downloading it in JOSM.

What I'm proposing to do is essentially just to finish off the building import that was started over a year ago in Ontario, though just within the bounds of the City of Toronto. That larger import, at the time, never reached the central parts of the city and there are about 55,000 buildings that can still easily be imported from the ODB. There is an outline of the proposal here ( https://wiki.openstreetmap.org/wiki/Toronto_building_import ) And I've uploaded some task-level OSM data to GitHub ( https://github.com/Nate-Wessel/TO-building-import/tree/master/tasks ) if anyone cares to inspect it. Hopefully this import process will address most of the concerns raised about the initial import, including those I raised myself ;-) Anyway, this email is just to notify y'all that I've been working on this again and to start the necessary discussions and get any feedback. I'd love to begin to move forward in the next couple of weeks if there is support for this effort here, and on the imports mailing list. Please let me know what you think!
