The Canadian government, primarily through the Canadian Commercial Corporation (CCC), is one of the United States’ biggest contractors. The CCC is a Crown corporation wholly owned by the Canadian government that, since 1946, has helped thousands of Canadian companies obtain over $30 billion in export sales. The single most important market for the CCC is the United States government, particularly the Department of Defense. Under the 1956 Defence Production Sharing Arrangement (DPSA) between Canada and the United States, the CCC acts as Canada’s contracting instrument supporting the Department of Defense’s military procurement needs. The DPSA requires Canadian defense contractors to conduct business through the CCC.
