A site constantly in flux: Boundaries, security and architectural evolution

Osgoode Hall has consistently evolved over nearly two centuries. A sense of institutional continuity emerged over these years, despite constant changes and additions, such as the iron fence.

The iron palisade and the “Cow Gates”

The fence features a series of vertical iron pickets topped with ornate, spear-like finials, anchored by stone plinths that mirror the masonry of Osgoode Hall itself. While the narrow, 20-inch “kissing gates” are frequently cited in popular anecdotes as a defence against wandering cows and pigs, this is largely considered conjecture. Sources indicate that by the 1860s, Toronto was a developed commercial centre where wandering stray livestock was rare. Furthermore, the cow narrative only gained widespread popularity after the 1933 publication of the fictional bestseller The Yellow Briar by Toronto lawyer John Mitchell. A more likely practical purpose for the gates’ restrictive design may have been strategic security and crowd control, since the gates allowed only one person to pass at a time, creating a defensible threshold for the property.

A building in flux

The building’s growth continued through the late 19th and 20th centuries with a series of major additions that transformed Osgoode Hall into a legal landmark. Between 1880 and 1882, William Storm independently designed the Convocation Hall, an examination space inspired by medieval Inns of Court in London, England (the professional associations for barristers). While the hall’s structural volume and balcony date back to Storm’s original 19th-century vision, its modern appearance — including the bookcases and interior finishes — is the result of a significant renovation in 1938. In addition, between 1986 and 1989, artist Christopher Wallis installed prominent stained glass windows depicting symbols of Canadian legal heritage. A later addition to the Great Library, the American Room was built in 1894–1895 by the firm Burke and Horwood. Designed specifically to house an expanding collection of American legal documents, the room features floor-to-ceiling oak bookcases and remains a key part of the building’s structural chronology, though it has since transitioned out of Law Society control. A full timeline of major additions and the building’s evolution can be accessed here.
 

In more recent years, Osgoode Hall has continued to be a building in flux. From a bird’s-eye view, it appears as a series of interconnected “parts” representing nearly 200 years of Canadian architectural evolution. While the iconic south facade of the late 1850s remains largely untouched, the building behind it has undergone continuous development to meet the growing needs of Ontario’s legal system. Designated a National Historic Site in 1979, the Hall remains a living landmark that continues to serve its original dual function as both a working courthouse and the home of the Law Society, preserving its legacy.
