Chern insulators must break time-reversal symmetry and topological insulators require time-reversal symmetry for protection. Both of them have nontrivial band structures and edge/surface states, the difference being that TI is nontrivial only with time-reversal symmetry (and the edge states are protected by the symmetry). – Meng Cheng.
