How many house were sold, reported on a month by month basis,
in Hamilton, Ontario Canada, starting January 2004 through to July
2005.

If the data is only available for Hamilton, combined with
neighboughing Burlington, Ontario Canada, then that is okay too
(ideally both Hamilton and Burlington reported seperately).

The following site contains the type of information I am looking for,
but not specific for Hamilton or Burlington.
