Border Security and Cooperation: Balancing Openness and Safety
The Canada-US border stretches nearly 9,000 kilometres, making it the longest international boundary in the world. For most of history, this border has been remarkably open, reflecting the friendly relationship between neighbours who share values, language, and extensive family and business connections. Since September 11, 2001, security concerns have transformed border management, creating tensions between the openness that economic integration requires and the security that both countries demand.
