After its closure in 1973 following 107 years of business, the entire block comprising King, Germain, and Prince William Streets would be demolished to pave the way for the development of Brunswick Square,[5] which completed in 1976.

[6] In November, a celebratory event took place, featuring the premier, Richard Hatfield, who cut a replica cake of the complex using a sword.
