Crossing international borders implies much more than simply going through checkpoints. Engaging major domestic political, technical, and administrative aspects that shape international policy and regulatory cooperation, this book uncovers and analyzes factors that govern economic activity and human interactivity across Canada's "fluid" borders in a changing geopolitical environment. Trade and investment policies must navigate the challenges from the interactions and limits of Canada's multiple commercial agreements with other countries that involve the bordering of energy trade, food safety, and related environmental and public health matters. By drawing on an innovative transdisciplinary reconceptualization of the border as being "fluid"-reflecting different and often cross-cutting objectives-Canada's Fluid Borders offers readers fresh outlooks on the leading geopolitical and socioeconomic issues pressing Canadian policymakers.
