Everywhere we turn in Canadian local politics - from policing to transit, education to public health, planning to utilities - we encounter a peculiar institutional the special purpose body. These "ABCs" of local government - library boards, school boards, transit authorities, and many others - provide vital public services, spend large sums of public money, and raise important questions about local democratic accountability. In Fields of Authority , Jack Lucas provides the first systematic exploration of local special purpose bodies in Ontario. Drawing on extensive research in local and provincial archives, Lucas uses a "policy fields" approach to explain how these local bodies in Ontario have developed from the nineteenth century to the present. A lively and accessible study, Fields of Authority will appeal to readers interested in Canadian political history, urban politics, and urban public policy.
