  We investigate the impact of topology on the phase structure of
four-dimensional Causal Dynamical Triangulations (CDT). Using numerical Monte
Carlo simulations we study CDT with toroidal spatial topology. We confirm
existence of all four distinct phases of quantum geometry earlier observed in
CDT with spherical spatial topology. We plot the toroidal CDT phase diagram and
find that it looks very similar to the case of the spherical spatial topology.
