On Friday, August 10, 1984, a provincial plaque commemorating the Peel County Court House was unveiled on the grounds of the former court house building, 3 Wellington Street East in Brampton.
In 1993, the Ontario Heritage Trust replaced the original plaque with a revised bilingual marker that reads:
PEEL COUNTY COURT HOUSE
This court house building, together with the adjacent jail and registry office, served as the judicial and administrative centre for the County of Peel for more than a century. Its prominent location on a rise of land and its stately appearance reflect the growing civic pride and affluence of 19th-century Ontario communities. Designed in the Italianate style by Toronto architect William Kauffmann, the court house was built by the contracting firm of Kesteven & Story. The onion-shaped dome atop the cupola is a unique feature in Ontario count house design. Opened in 1867, the building housed the county courts until 1973, when new facilities were built.
In addition, a second provincial plaque was unveiled on Thursday, September 6, 2007 by the Trust and the Peel Heritage Complex to commemorate financier, philanthropist and historian, William Perkins Bull.
The bilingual plaque reads as follows:
WILLIAM PERKINS BULL, K.C., LL.D. 1870-1948
Financier, philanthropist and historian William Perkins Bull was born in Downsview, Ontario, in 1870. Bull attended Osgoode Hall Law School and was called to the bar in 1896. He established a law practice but soon broadened his interests to include oil, lumber and land speculation. His business interests took him to England where, during the First World War, he and his wife Maria Brennan Bull established a convalescent hospital for wounded Canadian officers. Following the war he returned to Canada to continue his legal and business affairs. In 1931 Bull’s interest in history was spurred when he assembled a library of rare books by Canadian authors. He began a study of Peel County’s history that eventually grew into ten published volumes on Peel’s cultural and natural history. Perkins Bull was considered ahead of his time in recognizing the historical value of oral and written accounts, photographs, everyday objects and the built environment. He collected pioneer artefacts and Canadian art and much of this collection, including his research, is preserved at the Peel Heritage Complex in Brampton.
