Description

Osgoode Hall is a stately, Palladian-style building, erected in stages throughout the mid-19th century. It is surrounded by grassed lawns, and separated from the street by a stone and wrought-iron fence with elaborate entrance gates. The building and its property occupy an entire city block in the downtown business district of the city of Toronto. The formal recognition consists of the building on its legal property.

Heritage value

Osgoode Hall was designated a national historic site in 1979 because it represents the judicial institution in Ontario and the role of law in protecting Underground Railroad refugees from extradition, and because it ranks among Canada's architectural and historical treasures.

Since its construction in 1832, Osgoode Hall has served as the headquarters for the Law Society of Upper Canada, the governing body of the legal profession in Ontario. The building was named for William Osgoode, the first Chief Justice of Upper Canada. As law society headquarters, Osgoode Hall has provided a library, dining room and study space for practising lawyers since 1832. During the 19th century it also provided sleeping quarters for students-at-law. From 1889 to 1974 the law society operated a law school at Osgoode Hall, until 1959, the only one in the province. The law society continues to administer the bar admission course for Ontario from Osgoode Hall. Since 1846 Osgoode Hall has also served as a courthouse for senior provincial courts, and many important cases have been heard here. The Province has owned part of the building since 1874, with the Law Society retaining ownership of the East Wing and Great Library. Growth of both the law society and the court system prompted the numerous additions and alterations made to the building over the course of the 19th and 20th centuries.

In 1861, the highly publicized case of John Anderson was heard in the courtroom at Osgoode Hall. The Anderson case established a clear precedent against allowing refugee extradition back to the United States, thereby protecting Underground Railroad refugees from being returned as fugitive slaves.

Architecturally, Osgoode Hall represents a blend of Palladianism and Neoclassicism characteristic of mid-19th-century Canadian architecture. The original building was erected in 1829-32 to designs by John Ewart, assisted by Dr. W.W. Baldwin. The building's unusual plan and elevation are a result of numerous successive additions by a series of different architects. Centre and west wings were added in 1844-6 to designs by Henry Bower Lane, establishing the basic composition of the present building. Renovations by Cumberland and Storm in 1857 replaced the centre wing and added other significant decorative and structural components. In 1865, a law school was added to the rear of the East Wing, to plans by William Storm. Additions and alterations to the building continued throughout the 20th century.

In addition to its esteemed association with the legal profession and the provincial court system, Osgoode Hall is well-known for its commanding presence along Queen Street, and its elaborate interior spaces. These include the Great Library, the Rotunda, and a wood-panelled dining room for law society members. The distinctive wrought-iron fence and gates which surround the property were built by Hamilton and Son of the St. Lawrence Foundry, Toronto.
