In nineteenth-century Canada, the Square Mile was an elite residential district in Montreal that represented a dramatic new concentration of wealth. Montreal’s Square Mile chronicles the history of the neighbourhood, from its origins to its decline, including the diverse and far-reaching sources of its making and its twentieth-century transformations. Spanning the interconnected worlds of family and home life, business and high politics, architecture and urban redevelopment, this interdisciplinary and richly illustrated volume presents a new account of the Square Mile’s history and an investigation of the neighbourhood’s impact beyond the immediate urban environment.
