Does anyone know where I could source similar data to google's for buildings in a large city in Canada? I am looking for 3d, but if not possible, I could use 2D shapes instead.

Check the google 3D warehouse. i don't know if they offer collections of buildings, but you can search for individual ones. They will come as either a collada or sketchup format.

Try OSM's data (http://wiki.openstre...SM-3D#Buildings). I don't know what the building data coverage is for Canada's cities, though.

If that doesn't work (let us know if it does!), you can always fall back on OSM. Its buildings have been getting better, to the point where they're often acceptable for scales of 1:20,000 and smaller. No 3D though. (Maybe wait a few years for that!)

I was under the impression that commercial licensing is not available for Google Warehouse data? I will most likely be purchasing a dataset which includes 2D footprints from DMTI. (http://www.dmtispati...treetfiles.aspx) It's a fairly cost effective solution, but unfortunately their footprint data is approx 1.5 years old.

It's hard to imagine footprint data that's more recent than 1.5 years. Certainly not Google's. I work with buildings in Ottawa and Toronto all the time, and not only are Google's at least that old, their selection and depiction are also questionable. In any case, you'll have lots of revising and editing to do -- depending on the purpose / scale of the map, of course.

We've got downtown Vancouver pennisula buildings from 2004, entire downtwon core. Not sure which area's you're looking at though.

http://www.arcgis.com has Toronto data showing building footprints. It comes originally from the City of Toronto but they don't show it on their mapping site. You might be able to purchase data from them but it may be a little expensive.
