A nice abuse of owl:sameAs indeed :)
http://sws.geonames.org/6077244/ is Montr�al *Post Office* since its feature
code is S.PO, called simply "Montr�al" by laziness of the data curator ...
and mistaken as the city by some dumb script not leveraging geonames
classification to sort out homonyms.

Indeed. No one has taken the time so far to name Montr�al Post Office in
other languages.
But http://sws.geonames.org/6077243/ which is indeed the *City* of Montr�al,
does provide suite a bunch of them.

So data curation is needed :
- Specify the name(s) of http://sws.geonames.org/6077244/ on geonames side
to ease disambiguation (will do it)
- Correct the DBpedia dumb matching (I have no power on that one)

Cheers

Bernard
