How to programmatically detect a canvas refresh or pan/zoom in QGIS

Question

For my python plugin I would like to remove a VertexMarker when the user pans/zooms there map.

Which is the best way to detect a canvas refresh or pan/zoom carried out by the user?

Can you suggest any plugins which have this functionality I can take a look at?

Thanks
