The building also houses a smaller black box theatre, The Baby Grand, which seats 105 people.

Notable performers to appear at the theatre during its early years included Sarah Bernhardt, Al Jolson, and Nellie Melba.

Were it not for a group of concerned citizens forming the Kingston Arts Council, the Grand Theatre would have been demolished in the early 1960s.

[2] Work accordingly began in 1964 and the newly named The Grand Theatre opened its doors on 20 May 1966 with a performance of Dora Mavor Moore's musical revue Spring Thaw.

In 1978 a series of ongoing renovations began which established new lounges, higher quality backstage facilities, and The Baby Grand was co-founded by Sarah Garton Stanley and Eric Kaskens in 1985 (and was renovated and reopened in November 1990).
