Book excerpt: Municipal Boundary Battles explores the motivations, land use effects, and financial implications of municipal boundary adjustments across Canada, focusing mainly on annexations and amalgamations—the most frequent means to adjust boundaries and reform local governments in this country. With a focus on mid-size cities and small towns rather than major Canadian metropolitan areas, the authors uncover hidden motivations, untangle behind-the-scenes political machinations, and document the resulting conflict. Through empirical evidence, case studies, and examples, the collection helps develop generalizations and inform best practices for municipal boundary adjustments and reform. The contributors explain how the esoteric aspects of adjustments work in more practical applications, offering political scientists, geographers, municipal officials, and planning practitioners fresh perspectives that contradict much of the prevailing understanding of boundary adjustments.
