The answer should be yes.  Changing the content of the file causes the change 
of mtime.  mtime change is considered a change in the inode.  Any inode change 
will result in a ctime change.

An unrelated topic.  Solaris has a special file read mode that allows a
file being read without atime update.  It's a nice feature for backup
software.
