Occupying one block of the four-block Civic Esplanade that links City Hall to Riverside Drive, Charles J. Clark Square is named in honour of former lawyer Charles J. Clark, Q.C.
The square features an irregularly shaped skating rink, which transforms into a seasonal plaza with terraced seating. The built-in seating lines the east and west sides of the square. A trellis on the east side carries decorative and safety lighting. Two buildings at the north end of the square act as a gateway entrance. One provides a seasonal café and washrooms, while the other houses maintenance equipment. The rink opened December 2001.
