Book excerpt: Planning Canadian Regions was the first book to integrate the history, contemporary practice, and emergent issues of regional planning in Canada. This much-anticipated second edition brings the discussion up to date, applying the same thorough analysis to illuminate the rapid changes now shaping our regional landscapes and their planning. Special attention is paid to the regional planning dimensions of climate change adaptation and environmental sustainability, the development inequities faced in peripheral resource regions, the special role of Aboriginal peoples in regional planning, and the distinctive planning needs of metropolitan regions across the country. This book challenges planners, educators, and policy makers to engage with the latest thinking and strive for best practices in twenty-first century regional planning.
