Open Source Geocoding Engine

[Poopalasingham Elankeswaran]

Hi there,

I am doing research on Address gecoding with Mapserver and
PostgreSQL/PostGIS. Does anyone have any idea in this area? It is not like
Goole Map or Mapquest. This has to be specifically for Southern Ontario,
Canada. I need to search list of addresses and displaying them together on a
Map or save all the corresponding points to a shape file.

Is there any Open Source Geocoding Engine?

Thanks,
