In this paper the canonical representation of an A-contraction T on a Hilbert space H is used to obtain some conditions concerning the concept of A-ergodicity studied in [14-17]. The regular case and the case of R(A) closed are considered, and specifically, the TT*-contractions are studied. Some spectral properties are also given for certain particular class of A-isometries.
