Capital District Department of Public Security

The Capital District Department of Public Safety (CDDPS) is an executive department of the Capital District Municipal Council, the government of Ottawa, the federal capital of Canada. It is primarily responsible for overseeing the Metropolitan Police Department, Ottawa's local civilian police, whose chief constable answers to the municipality via the Secretary of Public Security and the Capital District Police and Crime Commissioner (PCC). The CDDPS also oversees the capital's emergency preparedness, and frequently liaises with the RCMP and Security Intelligence Service in matters of national security relevant to Ottawa as the federal capital.

The CDDPS headquarters is located at 1870 Alta Vista Dr, Alta Vista, Ottawa, near the headquarters of the Canadian government's Department of National Defence (DND).
