The Trenton Cenotaph was constructed in 1968 and dedicated in memory of the First and Second World Wars and the Korean War. Walter Gregory's design was chosen from a competition in 1967. The cost was covered by the Royal Canadian Legion Branch 110, its Ladies' Auxiliary and Branch 579 Quinte Ex Service Women.
Carl Taylor supervised construction and obtained the materials and contractors. The materials included rocks from an old Trenton post office representing the strong base Canadians rose from. Its triangular shape represents the three main branches of service, Army, Air Force and Navy. A broken column suggests lives that were cut off too early.
In 1988, it was rededicated in memory of the fallen of all conflicts. Two benches were added: one for the rededication and the second dedicated to the six crew lost in the sinking of HMCS Trentonian.
