Colour-Coded: A Legal History of Racism in Canada, 1900-1950 is a groundbreaking text that illustrates the undeniable assertion of deeply imbedded racism within Canada's legal system. From thousands of cases, legal scholar Constance Backhouse selected six court cases that focus on Aboriginal, Inuit, Chinese-Canadian, and African-Canadian individuals. Her detailed narratives tell the story of Eliza Sero, Tyendinaga Mohawk, who upholds the idea of Iroquois sovereignty in 1921; Dakota spiritual leader Wanduta's efforts to maintain his people's grass dancing tradition in 1903; and the case involving the legal definition of Inuit in 1939. Other cases examine Viola Desmond's challenge to racial segregation in Nova Scotia; Yee Clun's opposition to the White Women's Labour Law in Saskatchewan; and combating the Ku Klux Klan in Oakville, Ontario. In each case study the author outlines the people, context, and the legal question with clarity and precision. Extensive documentation is included in the text, and more details are included on the University of Toronto Press website for scholars who wish to examine all the endnotes. Reading these cases leaves no doubt that Canada's legal system played a major role in creating and upholding racial discrimination. Constance Backhouse is professor of Law at the University of Western Ontario. This text is recommended for senior high school, college and university.
