We propose a renormalizable $T'$ flavor model based on the $SU(3)_C\timesSU(3)_L\times U(1)_X\times U(1)_{\mathcal{L}}$ gauge symmetry, consistent withthe observed pattern of lepton masses and mixings. The small masses of thelight active neutrinos are produced from an interplay of type I and type IIseesaw mechanisms, which are induced by three heavy right-handed Majorananeutrinos and three $SU(3)_L$ scalar antisextets, respectively. Our model isonly viable for the scenario of normal neutrino mass hierarchy, where theobtained physical observables of the lepton sector are highly consistent withthe current neutrino oscillation experimental data. In addition, our model alsopredicts an effective Majorana neutrino mass parameter of $m_{\beta} \sim1.41541\times 10^{-2}$ eV, a Jarlskog invariant of the order of $J_{CP}\sim-0.032$ and a leptonic Dirac CP violating phase of $\de = 238^\circ$, which isinside the $1\sigma$ experimentally allowed range.
