I think, Reader will be available soon in South (Latin) America.

If you type PRS-500 in a "model" window at this page:
http://esupport.sony.com/CA/perl/sel...CS&PRODTYPE=74

you will see:

Model Find
The model you have entered is only available in the following regions:

Latin America
United States

And here you can choose a model from a list...
http://esupport.sony.com/LA/perl/sel...CS&PRODTYPE=74
...and get manuals for Latin America region:

Reader from Canada is not available... But it's ok from Latin America. Strange...
