Despite a renovation in the 1990s, the courthouse remained inaccessible to the public on a daily basis. After an extensive renovation, currently active, it will host staff offices, a board room, and the Art Gallery of Peel's public reference library. The Courtroom and Council Chamber will be available for rentals.
