If you are using an interactive session, then ctrl-C can't kill the local ssh process (think about it for a moment and you'll realise why). For interactive sessions you should use the Disconnect escape sequence described in the "ESCAPE CHARACTERS" section of "man ssh".

Usually "<enter>~." unless you have overridden it.

Cleanup channels when using ControlMaster and ~.

Also note that there is a known bug when using ControlMaster (ie mux mode) where the escape sequence ~. does not work in the ControlMaster client.  If this is what you're seeing please try the attached patch.
