Both two and three level domain cases are handled where the two
level domains can be anything.ca that are not listed as a known
geographic TLD like on.ca (for Ontario province) and where the
three level domain would be under a known two level TLD such
as anything.on.ca.

A fourth level geographic domain, for example under a city name,
may not be handled properly, but could be added.  If we drive
spammers to be desperate enough to use those then we've already
had great success.  :-)
