Roberto,

I haven't tried it myself, but the following should work:

myCanvasItem.setCanvas(None)

I assume you're having problems getting rid of the python object because 
it is still owned by the canvas it was on. If you remove it from the 
parent canvas before you try to delete it you may have more luck.

Cheers, Solly
