We report a measurement of the ${\ensuremath{\nu}}_{\ensuremath{\mu}}$ charged current quasielastic cross-sections on carbon in the T2K on-axis neutrino beam. The measured charged current quasielastic cross-sections on carbon at mean neutrino energies of 1.94 GeV and 0.93 GeV are $(11.95\ifmmode\pm\else\textpm\fi{}0.19(\text{stat}{)}_{\ensuremath{-}1.47}^{+1.82}(\text{syst}))\ifmmode\times\else\texttimes\fi{}1{0}^{\ensuremath{-}39}\text{ }\text{ }{\mathrm{cm}}^{2}/\text{neutron}$, and $(10.64\ifmmode\pm\else\textpm\fi{}0.37(\text{stat}{)}_{\ensuremath{-}1.65}^{+2.03}(\text{syst}))\ifmmode\times\else\texttimes\fi{}1{0}^{\ensuremath{-}39}\text{ }\text{ }{\mathrm{cm}}^{2}/\text{neutron}$, respectively. These results agree well with the predictions of neutrino interaction models. In addition, we investigated the effects of the nuclear model and the multi-nucleon interaction.
