The OP stored the ls arguments (including the filename with its space)
in an array, and the array expansion isn't happening correctly:

  address@hidden:tmp$ lsargs=(-l -a -r -t "dir with spaces")
  address@hidden:tmp$ ssh toto <<EOF
  ls "address@hidden"
  EOF

  Pseudo-terminal will not be allocated because stdin is not a terminal.
  ls: invalid option -- ' '
  Try `ls --help' for more information.
  address@hidden:tmp$ ssh toto <<EOF
  printf "<%s>\n" ls "address@hidden"
  EOF

  Pseudo-terminal will not be allocated because stdin is not a terminal.
  <ls>
  <-l -a -r -t dir with spaces>
  address@hidden:tmp$ ssh toto <<EOF
  printf "<%s>\n" ls address@hidden
  EOF

  Pseudo-terminal will not be allocated because stdin is not a terminal.
  <ls>
  <-l>
  <-a>
  <-r>
  <-t>
  <dir>
  <with>
  <spaces>

I'm not sure there's a good way to do this.
