A new Monte Carlo event generator MCSANCee for simulation of processes at future e^+e^- colliders is presented. Complete one-loop electroweak radiative corrections and polarization of the initial beams are taken into account. The present generator includes the following processes: e^+e^- \to e^+e^- (mu^+mu^-, tau^+tau^-, ZH, Z\gamma, \gamma\gamma). Numerical results for all of these processes are shown together with tuned comparisons with other existing codes. The plan for the further extension of the MCSANCee generators are discussed.
