Thanks Nikem for the link.

I didnt install the libvorbis liobrary (could find it in the Toumas repository). But I had the older OGG support package installed.
I only installed the ogg-spupport-lms.deb file (had to do from command line, using dpkg, it didnt work from the Application manager).

Now Canola does show and play all my ogg files beautilfully.
Thanks for the helping hand everyone.
