We argue that the A{sub 4} symmetry as required by three flavors of fermions may well-embed in the SU(3){sub C} x SU(3){sub L} x U(1){sub X} gauge model. The new neutral fermion singlets as introduced in a canonical seesaw mechanism can be combined with the standard model lepton doublets to perform SU(3){sub L} triplets. Various leptoscalar multiplets such as singlets, doublets, and triplets as played in the models of A{sub 4} are unified in single SU(3){sub L} antisextets. As a result, naturally light neutrinos with various kinds of mass hierarchies are obtained as a combination of type I and type II seesaw contributions. The observed neutrino mixing pattern in terms of the Harrison-Perkins-Scott proposal is obtained by enforcing the A{sub 4} group. The quark masses and Cabibbo-Kobayashi-Maskawa mixing matrix are also discussed. By virtue of very heavy antisextets, the nature of the vacuum alignments of scalar fields can be given.
