Looks like hell has frozen over — there’s now an Ontario open buildings layer that’s compatible with the OSM licence: The Open Database of Buildings. Thanks go to StatCan for aggregating all the data sets into one huge database.
A small sample is here: scruss/Neighbourhood_Buildings.geojson
A certain sarcastic file format will be pleased to know that it’s all packaged as one gigantic shapefile.
