In May 2009, the Mohawk people of Akwesasne occupied the area around the Canada Border Services Agency port of entry building to protest the Canadian government's decision to arm its border agents while operating on Mohawk territory. The north span of the Seaway International Bridge and the CBSA inspection facilities were closed. During this occupation, the Canadian flag was replaced with the flag of the Mohawk people. Although U.S. Customs remained opened to southbound traffic, northbound traffic was blocked on the U.S. side by both American and Canadian officials. The Canadian border at this crossing remained closed for six weeks. On July 13, 2009, the CBSA opened a temporary inspection station at the north end of the north span of the bridge in the city of Cornwall, allowing traffic to once again flow in both directions.
