Covering nearly 4,000 miles of land and water from Washington to Maine, the U.S.-Canadian border is the longest undefended border in the world. The U.S. Customs and Border Protection, in collaboration with other fed., state, local, tribal, and Canadian entities have the primary responsibility for security. The Sec. of Homeland Security is required to submit a report to Congress that addresses the vulnerabilities along the northern border, and provides recommendations and required resources to address them. This report examined: (1) the extent to which the DHS report to Congress is responsive to the legislative requirements; and (2) actions that may be necessary to address northern border vulnerabilities in addition to the actions addressed in the report.

Covering nearly 4,000 miles of land and water from Washington to Maine, the U.S.-Canadian border is the longest undefended border in the world. Various Department of Homeland Security (DHS) component agencies share responsibility for northern border security, primarily U.S. Customs and Border Protection (CBP), in collaboration with other federal, state, local, tribal, and Canadian entities. The Implementing Recommendations of the 9/11 Act of 2007 required the Secretary of Homeland Security to submit a report to Congress that addresses the vulnerabilities along the northern border, and provides recommendations and required resources to address them. The act also required GAO to review and comment on this report. In response to this mandate, GAO examined (1) the extent to which the DHS report to Congress is responsive to the legislative requirements and (2) actions that may be necessary to address northern border vulnerabilities in addition to the actions addressed in the report. To conduct this work, GAO reviewed DHS plans, reports, and other documents, and interviewed DHS officials.

"The challenges of securing the U.S.-Canadian border involve the coordination of multiple partners. The results of the Department of Homeland Security's (DHS) efforts to integrate border security among its components and across federal, state, local, tribal, and Canadian partners are unclear. GAO was asked to address the extent to which DHS has (1) improved coordination with state, local, tribal, and Canadian partners; (2) progressed in addressing past federal coordination challenges; and (3) progressed in securing the northern border and used coordination efforts to address existing vulnerabilities. GAO reviewed interagency agreements, strategies, and operational documents that address DHS's reported northern border vulnerabilities such as terrorism. GAO visited four Border Patrol sectors, selected based on threat, and interviewed officials from federal, state, local, tribal, and Canadian agencies operating within these sectors. While these results cannot be generalized, they provided insights on border security coordination. "
